DRONETECH Introduction to Imagery and Geospatial Analysis Webinar
Steve Sorenson: Okay well it's 10 o'clock with that. Steve Sorenson: Now about 13 people on so. Steve Sorenson: Wait a couple more minutes and then we'll get started here. Steve Sorenson: we'd ask that you keep your microphones muted unless you're going to talk, but the prefer, yes, the questions on chat.
Steve Sorenson: Down below or moderator will feel those questions and either refer them up to be are answering themselves. Steve Sorenson: So I think about it for the administrative announcements and. Steve Sorenson: still get yourself a cup of coffee and we go in here and i've interrupted. Steve Sorenson: Okay, well, welcome to introduction to imagery and geospatial analysis.
Steve Sorenson: i'm Steve sorenson i'll be. Steve Sorenson: Presenting for most of the session here the last hour will be Kirk stevie from St cloud State University and he will be talking to you about every cultural applications. Steve Sorenson: When we. Steve Sorenson: get started into this brief introduction i'm the geospatial intelligence Now this is Dr that Northern community and technical college and thief river falls medicine. Steve Sorenson: So that's a mouthful but. Steve Sorenson: we're here to talk about imagery analysis so.
Steve Sorenson: we'll get started, we do plan on breaking or I do plan on breaking every hour for about 10 minutes just let everybody's brains reset. Steve Sorenson: give you time for a bathroom break or to grab more coffee so. Steve Sorenson: Not gonna torture you for two hours straight.
So. Steve Sorenson: Dirty in. This isn't looking right. Steve Sorenson: Sorry for my technically challenged skills. Steve Sorenson: Instead of what what makes a geo referenced image will get into that later we'll talk about what is imagery and then what makes GEO referenced image. Steve Sorenson: Creating mosaics and then there'll be practical exercise.
Steve Sorenson: Hopefully you've all received the email with the link to download. Steve Sorenson: Google earth pro and there are also some. Steve Sorenson: excel documents and images that can be downloaded or should be downloaded will be using those in the practical exercises So if you haven't done that, yet you might want to do that, while i'm talking. Steve Sorenson: Or we can take time at the end and do that so. Steve Sorenson: Okay, so what is imagery.
Steve Sorenson: imagery can be defined, and this is a Webster definition here pictures produced by an imaging system, the product of image makers figurative language and mental images. Steve Sorenson: And we're going to use that mental image, right now, so. Steve Sorenson: The saying is a picture can. Steve Sorenson: can tell 1000 words to speak the thousand words, so I want you to visualize your hands, right now, a cow in a field.
Steve Sorenson: So now you got that mental image of a column field. Steve Sorenson: So outside of a. Steve Sorenson: cow and field.
Steve Sorenson: Will kind of other information you think we can pull from that image. Steve Sorenson: It look at the mental image and go. Steve Sorenson: What kind of cow is it. Steve Sorenson: What type of field.
Steve Sorenson: What time of day, is it. What time of year. Steve Sorenson: All these things can be pulled out of that image that information is there in an image. Steve Sorenson: Analysts can tell you sentences so as you're saying they see that image and they're identifying all those little parts within that image and pulling it out. Steve Sorenson: So you can go from an image, you can go to broad overviews to down to the minute my new details within an image. Steve Sorenson: So what is imagery analysis.
Steve Sorenson: Now let's divide is the extraction of meaningful information from the images, mainly from digital images, by means of a digital image processing techniques so. Steve Sorenson: You can either. Steve Sorenson: visually use your eyes or there are software's out there, that will help pull up. Steve Sorenson: Those details. Steve Sorenson: In the image and also help you. Steve Sorenson: Real Estate altar but change the components within so there's many different types of imagery.
Steve Sorenson: You can have like infrared near infrared photographic or 14 rematch photo grand entry. Steve Sorenson: For photo dramatic. Steve Sorenson: imagery is the basic photo injury and lidar there are also other types of imagery like bathmat tree, which is basically lidar for underwater. Steve Sorenson: All these different types of imagery utilize different elements or spectrums in capturing that image and by manipulating the. Steve Sorenson: Elements or components in there, you can bring out differences.
Steve Sorenson: In the spectrums are in what you're looking at to help you identify what it is. Steve Sorenson: And then, also in analyzing images or imagery you look at activity what's going on in the image. Steve Sorenson: For focus, what is the focus of the image. Steve Sorenson: So you can have a picture. Steve Sorenson: of activities say it's a football game. Steve Sorenson: The focus of that picture is generally going to be the Center of the image, so at this screen was the image.
Steve Sorenson: This whole screen was the image, the focus would be here in the Center. Steve Sorenson: that's what the photographer or the image taker wants you to focus on what's in the Center. Steve Sorenson: But as an analyst or analyzing imagery that's where you start, but you also look at the outer edges, because the outer edges will tell you more of what's going on. Steve Sorenson: And then to add to that the culture or environment of that subject image So where is it what is the surrounding environment, like the surrounding physical and social culture How does that affect.
Steve Sorenson: And we'll get into that a little later this afternoon to. Steve Sorenson: Other things we use to identify things in images or shadows shapes and positional relationships so shadows as. Steve Sorenson: My fellow instructor always says shadows are your friends shadows help you identify what's in an image, so you can see, see the shadows see an object you don't know quite what it is look for its shadow, and the shadow often defines what the actual image is. Steve Sorenson: shapes Obviously there are certain shapes in nature that just don't occur naturally and those will give give away what's down on the on the ground, or whatever you're looking at and positional relationships so where it is in relation to.
Steve Sorenson: Whatever else you're looking at. Steve Sorenson: can help you identify. Steve Sorenson: or indicate what you might be looking for. Steve Sorenson: So here we have an image.
Steve Sorenson: And it's a residential area. Steve Sorenson: So here's here's where you get to participate in turn off your mics and answer when I asked questions here. Steve Sorenson: it'll make it more interesting. Steve Sorenson: So it's a residential area, but what else do we see. You.
Terra McKee: know. Steve Sorenson: there's a car. Steve Sorenson: What do you notice about the car. Terra McKee: it's traveling strike looks like it's just going down the room.
Steve Sorenson: does have a shadow. Terra McKee: A bit. Terra McKee: A little bit yeah. Steve Sorenson: it's it's got a slight shout out. Steve Sorenson: What else do we know about the area, the image.
Byron Latil: It would appear that the roadway surfaces compromised. yeah. Steve Sorenson: So if you're if you're doing a survey of road conditions, the Sierra image could provide you with some good information on that.
Steve Sorenson: That you might not be able to see from standing on the ground, looking down the road. Steve Sorenson: What else do we see. Lee Rafalko: i'm guessing it's springtime. Lee Rafalko: it's before the trees have started blue. Steve Sorenson: it's a good analysis yeah i'm. Steve Sorenson: As, why do you think it's spring olives and the trees are starting to bloom what other indicators might be out there to tell you that it's spring.
Steve Sorenson: Look at the art, are they full leaves. Steve Sorenson: they're not if it was fall, you probably have a lot more leaf debris on. Steve Sorenson: Yes, the budding of the trees does. Steve Sorenson: strongly indicate that it is.
Steve Sorenson: springtime that in the absence of. Steve Sorenson: Actual leaves. Steve Sorenson: So what else can we notice about the picture. Paul Agamata: looks like it's a midday saw. Steve Sorenson: Okay, why do we think it's a midday show. Paul Agamata: shadows, on top of each other.
Steve Sorenson: Yes, shallow shadows yeah there's not much of the shadows that's like when she. Steve Sorenson: When she mentioned that the car has a slight shadow yeah that's the general that indicates his son is Dr Morris directly overhead. Steve Sorenson: So, by looking at this we've been able to determine the time of day time of year. Steve Sorenson: that's about it. Roy Mason: it's probably not in southern California. Steve Sorenson: yeah that's.
Roy Mason: That would be a good I was. Steve Sorenson: gonna say we could try and nail down, where it is but there's a lot of area where that could be but southern California would not be one of them or Arizona or new Mexico. Steve Sorenson: But no so that's how we try and identify things what is. Steve Sorenson: This right here. Steve Sorenson: This is the object that's the shadow.
Tim Tumelty: stops on. yeah. Steve Sorenson: And you notice, you see the STOP sign here there's another one on this side over here little longer shadow. Steve Sorenson: What about this right here.
Terra McKee: You have some light pole. Steve Sorenson: yeah it's a street light same with over here. Steve Sorenson: So you can tell you, if you looked right at the pole you wouldn't necessarily know it. Steve Sorenson: But you see the shadow. Steve Sorenson: Can you like, I know what that is.
Kathy Kanemoto: So maybe you could calculate how tall is polls are. Steve Sorenson: Good. Steve Sorenson: Depending on the the shadow length time of day. Steve Sorenson: There are ways of doing it's not exactly a good shot because it's directly above, but the measurement of this. Steve Sorenson: The pole here, compared to a measurement of.
Steve Sorenson: A known object on the ground, there are ways to do that to figure out what the. Steve Sorenson: The length of that pole would be. Steve Sorenson: But yeah you can do that. Steve Sorenson: hey we've got another picture here, this is a tough one, what does this. Grant Onokah: looks like an airport yeah. Steve Sorenson: And now, for the obvious question why do we know it's an airport.
Scotty B Laptop: planes. Steve Sorenson: The point is a dead giveaway. Steve Sorenson: So on this one we've been airport. Steve Sorenson: Again, we can see like condition of the runways and taxiways here. Steve Sorenson: um. Steve Sorenson: What about.
Steve Sorenson: time of day. Paul Agamata: Still looks like midday, based on the weather vane shadow yeah. Steve Sorenson: yeah. Steve Sorenson: Oh, and that, by the way, is that what you're referring to is the weather being. Paul Agamata: yeah I think so.
Steve Sorenson: Now that's actually a jet. Paul Agamata: Oh, is that right okay. Steve Sorenson: This month small fighter jet.
Scotty B Laptop: They. Scotty B Laptop: can tell us. Scotty B Laptop: Thank you tell us where it possibly is, because how many airports have a fighter jet and a front of them like that. yeah. Steve Sorenson: So, and the other thing this was taken from Google earth and if you're looking at it on Google earth and we'll get into this a little next hour. Steve Sorenson: But it gives you the latitude and longitude right here of wherever the cursor was when the picture was copied so if we have this up on Google earth and I move my cursor over.
Steve Sorenson: The aircraft there, it would give me the exact latitude longitude. So. Steve Sorenson: So location would be fun to find easy fun um.
Steve Sorenson: What time of year, is it. Scotty B Laptop: Well, if this is agricultural probably it was like a field decided there and so there's nothing coming out of the ground so it's either been churned up or it's a setting idle for the winter. Steve Sorenson: Okay, it is agricultural land. Steve Sorenson: If it were winter.
Steve Sorenson: What would we expect to see in the field. Steve Sorenson: It may have been turned up for for winter. Steve Sorenson: But if it was what would we also see in the field. Steve Sorenson: there'll be a lot of stumbling debris. Steve Sorenson: The other indicators, what is this here.
Steve Sorenson: anyone have any ideas. About. Steve Sorenson: yeah that's a drainage. Steve Sorenson: Going on yo yo I say dicks because it's not really a digital appeal, but it's a low spot for the field to drain fields drainage of these areas here, these darker areas that's where the ground is still saturated of water.
Steve Sorenson: So this is actually in the springtime. Steve Sorenson: So less feel debris more dampness in the ground. Steve Sorenson: Anyone know why all these cars are parked here and zach can answer this question. Grant Onokah: Probably the COP. Steve Sorenson: yeah.
Steve Sorenson: This is, this is the aerospace campus for northland. Steve Sorenson: So this is a school building here, these are the. Steve Sorenson: Actually, these are the old hangers here there's new buildings in here and that's our maintenance hangar so it's. So. Steve Sorenson: easy for me, I know this place.
Steve Sorenson: Okay now something a little different. Steve Sorenson: Anyone know what this one is. Steve Sorenson: it's kind of an obvious answer yes it's a farm. But.
Steve Sorenson: This area here is a research firm. Steve Sorenson: And all these are individual crop plots. Steve Sorenson: So, as you can see some of them aren't planted right here, others are planted. Steve Sorenson: And in varying degrees of health and condition. Steve Sorenson: If I remember right, these are soybeans up here. Steve Sorenson: And this is wheat.
Steve Sorenson: What do you notice about the week here. Scotty B Laptop: I mean appears to be a little more or less dense So you can see a little Gray stretching through so maybe the spaced out a little bit. Steve Sorenson: A fair assessment if we could zoom in better you get closer you get a better idea of what that actually is is. Steve Sorenson: logic which is where the wind is blowing the weed over. Steve Sorenson: So heavy winds come through and blowing the wheat over and that's caused some logic in there and that's what the lighter color is in the wheat.
Steve Sorenson: We also have another phenomena out here. Steve Sorenson: You notice this field that all looks the same except for these blotchy patches through here. Steve Sorenson: Especially the later ones. Steve Sorenson: And that is the green part is a. Steve Sorenson: it's right field.
Steve Sorenson: Right grass, but the the blotchy parts in here. Steve Sorenson: is actually winter wheat. Steve Sorenson: Which is a certainly a weed and less it's in your rifle it's a we've. All. Steve Sorenson: The fun things we do. Steve Sorenson: But that's what what you can do with imagery on this is your identify where those problems are.
Steve Sorenson: And then you can. Steve Sorenson: draw polygons around them mark those that import that into the agricultural software and create. Steve Sorenson: spraying prescriptions for herbicides and nutrients fertilizers, in the field, so instead of having to broadcast spray the whole field you just precision spray the areas that you need. Steve Sorenson: So that's a use for that. Steve Sorenson: Okay, another scenario. Steve Sorenson: Obviously, this is not Minnesota.
Steve Sorenson: What do we have down here. Grant Onokah: looks like a crater. Steve Sorenson: yeah it's a depression, how do we know that. Grant Onokah: The shadows on the side.
Grant Onokah: of perception of depth as well. yeah. Steve Sorenson: The shadows. Steve Sorenson: And what do we have here. Steve Sorenson: Besides, a big. Grant Onokah: on innovation.
Steve Sorenson: that's a hill. Steve Sorenson: And this will be a rich. Steve Sorenson: which makes these. Steve Sorenson: ravines.
Steve Sorenson: And fingers in between the readings. Steve Sorenson: So, by looking at that and identifying those features, we can see, or better perceive the elevation. Steve Sorenson: In the image.
Steve Sorenson: What about the terrain. Steve Sorenson: lush vegetation or sparse sagebrush. Scotty B Laptop: Yes. Steve Sorenson: Now let's it's more sparse. Steve Sorenson: that a lot of different things in here to looks like residential over here industrial appear. Steve Sorenson: This one i'm kind of out on the can tell that's residential or this.
Steve Sorenson: could be a mix of both. Steve Sorenson: But what do we have right here. Paul Agamata: river bed try. Steve Sorenson: yeah so dry riverbed.
Grant Onokah: So where do we think we've. Steve Sorenson: taken. Steve Sorenson: On the breach yeah. Steve Sorenson: So where do we think regionally, this might be.
Roy Mason: Southwestern united. Steve Sorenson: States yep. Steve Sorenson: Does anybody know exactly.
Adam M: what's on Arizona yep. Steve Sorenson: that's it a mom tucson Arizona. Steve Sorenson: Anything else you see in this image that stands out. Byron Latil: A large a on the hillside yeah. Steve Sorenson: there's no secret to this i'm just asking because. Steve Sorenson: i've covered it a couple times, and as you become more familiar with your images sometimes you forget about that you miss things.
Steve Sorenson: that's all I have for that part we can certainly pull up. Steve Sorenson: Google earth here. Steve Sorenson: Take a look at some other imagery. Steve Sorenson: Financial.
Steve Sorenson: buried. Steve Sorenson: Okay. Steve Sorenson: So this is Google earth pro he will come back to this guy.
Steve Sorenson: Somebody pick a place any place. Roy Mason: It looks like the California southern California coastline, to me, but. Steve Sorenson: yeah that's where it was. trying to get a. Steve Sorenson: New it's concerning me they're. trying to get my.
Steve Sorenson: utah right. Roy Mason: it's hard to tell but it almost looks to me like like that might be the salton sea down in the left hand corner there. Roy Mason: yeah yes.
yeah. Roy Mason: it's about a second. Steve Sorenson: song senior the great salt lake.
Steve Sorenson: With me they. Steve Sorenson: Create self so. Roy Mason: yeah that's that's too far north for the salton sea. yeah. Roy Mason: So you're probably right the great salt lake which puts us all up into utah.
Scotty B Laptop: me right there at area 51 you could zoom in there. Steve Sorenson: Oddly enough you mentioned. say, I think.
Steve Sorenson: elbow kill for them so area 51 should be. Steve Sorenson: guess somewhere in here. Steve Sorenson: You know what happens if you'd be zoom into that area in Google Earth.
Steve Sorenson: it's no big earth shattering thing it's not like you know sirens and buzzers go off or something like that. Steve Sorenson: For some reason my Google Earth is just in a cooperate. Steve Sorenson: What happens is the screen becomes very blurry.
Is what happens so. Steve Sorenson: They just blow it out that's that's how they deal with it. Scotty B Laptop: yeah they don't want to see those aliens are those high tech 50 year old 50 year and advanced spaceships and everything all. The screens.
Steve Sorenson: Try and share your stuff. So. Steve Sorenson: What you can notice you do see like some terrain features, if you tilt the world. Steve Sorenson: As they say press down on the Center of scroll button on your mouth and then move it forward and back it it'll. Steve Sorenson: tilt your world which really becomes a.
Steve Sorenson: Rather outstanding when you get into 3D. Steve Sorenson: So you can give you that different perspective of. Steve Sorenson: Of the land in the tree. Steve Sorenson: So. Steve Sorenson: We give this one more try. Steve Sorenson: you're not wanting to go for it.
Steve Sorenson: try and make do with this one. Steve Sorenson: Any other areas, you might want to take a look at. Steve Sorenson: favorite vacation spot historical area. Steve Sorenson: can take it to the bottom of the ocean Oh, we should good. Roy Mason: How about there were the Colorado river empties into em empties into the Gulf there yeah interesting to see what's going on in that base and.
Steve Sorenson: see where the River dopes. Steve Sorenson: We talked about this area right in here. Steve Sorenson: or. Steve Sorenson: Looking to me like it's done here.
And it looks to me the car. Okay. Steve Sorenson: Sometimes it takes a while to catch up so. Roy Mason: Well, now that dark spot you're seeing there, that is, the salton sea managed to keep going farther the Colorado river is the border between Arizona and California and then it dumps there.
Roy Mason: into the golf. Roy Mason: yeah. Steve Sorenson: So that's the salton sea then it's going to dump into the Gulf here. Roy Mason: Yes, that's correct. Roy Mason: that's Mexico to each side.
Steve Sorenson: So you'll notice the. Steve Sorenson: The plumage here. Steve Sorenson: So thing comes down. Roy Mason: And that that's interesting because it gives us an idea of the depth of the water and the mixture of the salt water and the fresh water so lots of information there. Steve Sorenson: Oh yeah. Steve Sorenson: Now, when there's.
Steve Sorenson: Depending on the imagery you using. Steve Sorenson: The data, you can get even deeper into that as to just how much. Roy Mason: And you know from from an agricultural side again i'm from southern California, and this is an area my interest, but you can see the desert there. Roy Mason: And, but then, as you go farther North that's all irrigated farmland everything south of the salton sea and it's all irrigated because of the Colorado river going through there without the Colorado river. Roy Mason: You know a lot of the vegetables were getting in Minnesota during the wintertime wouldn't be there. Steve Sorenson: yeah no I agree.
Roy Mason: that's. Steve Sorenson: So huge source and then there's the salt and now that's pretty much landlocked to my understanding there's no. Roy Mason: Oh yeah yeah the salton sea is actually an artificial see it was created, back in the early 1900s because they irrigation dams etc broke and allowed it to be flooded and then over the years, because there is no natural input it's just dried up. Steve Sorenson: Right.
Steve Sorenson: which makes me wonder what if they. Steve Sorenson: How could they push that water out and if they did, where to go because. Steve Sorenson: What are they ecological impacts of throwing that into the ocean or. Steve Sorenson: draining itself into the Gulf here. Roy Mason: Well, you know my my students tell me i'm old as dirt but.
Roy Mason: I remember, I can remember going to the salton sea when it was a beautiful big huge see with fresh water and you could. Roy Mason: You could water skiing it, it was a great area and of course now over the last 50 years it's just shrunk down and there's such a high salt content nothing, nothing lives in it, but. Roy Mason: yeah it was artificial To begin with, and at this point in time, the water is just being reclaimed by the earth. Steve Sorenson: Might might be able to mind salt off it later. Roy Mason: yeah there you go. Steve Sorenson: that's about all I have for this session here.
Steve Sorenson: Before we go on break, are there any other questions. Steve Sorenson: Comments input. Steve Sorenson: it's a bueller but I don't do it, as well as Ben Stein.
Steve Sorenson: Well, if there is not why don't we take like a 10 to 15 minute break let you guys get up stretch a little more coffee and we'll come back at it. Steve Sorenson: Okay we're back. Steve Sorenson: And yes, I finally got my Google Earth. Steve Sorenson: siam National Park. In utah.
And as you can see, and. Steve Sorenson: zoom down. Steve Sorenson: tilt the world, you can get a better idea relief. Steve Sorenson: that's if you have the train clicked here don't have the train click it makes pretty sure. Steve Sorenson: If you turn on the train feature, then you get a lot better. So.
Steve Sorenson: With that later. Steve Sorenson: So any questions, to begin with, before we dive into geographic information systems, a brief overview, this will be by no means a thorough. Steve Sorenson: Investigation geographic information system. Steve Sorenson: Especially for job in our GIs because you need a four year degree or a master's to capture everything.
They can be pretty intensive. minute or two here. Steve Sorenson: say let Tom know in the chat if you want me to keep the webinar open over lunch is kind of an open open talk forum. Steve Sorenson: If you do just them and say, I would like me to keep it open over lunch and.
Steve Sorenson: we'll do that. here. Steve Sorenson: So geographic information systems or GIs for short.
Steve Sorenson: So when you when you hear that term GIs that's. Steve Sorenson: that's where it is it's geographic information system, there are lots of different ones out there. Steve Sorenson: Google Earth is kind of rudimentary one our GIs. Steve Sorenson: is probably the most widely used one here in us. Steve Sorenson: In Europe bird ass is very popular in. Steve Sorenson: Those ones like Q GIs and some other.
Steve Sorenson: Entities like john deere has their own system take machinery has their own and service caterpillar so there's several different companies have their own different geographic information systems that they use some more tailored to their own specific purposes. Steve Sorenson: So. Steve Sorenson: Understanding geographic information systems, what is gx you have it's. Steve Sorenson: Very shortly and quaintly is a digital man. Steve Sorenson: But it's more than that. Steve Sorenson: So traditionally up until about the 60s, we had traditional paper maps, so your typical fold out roadmap your usgs map topographic map.
Steve Sorenson: there's many different kinds, but they are all limited as in just the paper that it's on is what you're working with so that's the only area, you have. Steve Sorenson: large or small it's it's that pairing with the GIs geographic information is the digital map you're able to cover anywhere in the world that's been that long as somebody mapped it recorded, you can get. Steve Sorenson: using satellite imagery and the traditional surveying information. Steve Sorenson: That is all tied to. Steve Sorenson: The GEO locations which we generally refer to in latitude and longitude below there are several different ways they're recording that there's different systems, whether it be the lat long hours minutes degrees or its digital. Steve Sorenson: formation.
Steve Sorenson: or depending on which you use. Steve Sorenson: They can all be converted to a system that will work for what whatever system you're working. Steve Sorenson: So visual represented the creation of the earth and the advantage that GIs gives you is spatial relations. Steve Sorenson: So you can better see. Steve Sorenson: The environment terrain and other features and information that are around. Steve Sorenson: The specific subject you're looking at how that can influence that or how the significant influence that environment.
Steve Sorenson: So it's like we're talking about the salt and see how the River influences that area as far as agriculture, how the sea and desert climate environment of that area can influence the salton sea and agriculture. Steve Sorenson: So traditional mapping that several times you typically see like your street maps type of graphic maps. Steve Sorenson: different scale maps but they're all flat paper maps is what you use the word people would make relief minutes, what is actually. Steve Sorenson: scale representation of diverse terrain. Steve Sorenson: That. Steve Sorenson: Those are possible and have been done, but now you've got that all in digital format, so you can expand or shrink in that area.
Steve Sorenson: rapidly, and that will, without having to print w then. Steve Sorenson: Then you have relief maps of this so like you train maps here. Steve Sorenson: So graphic maps with relief. Steve Sorenson: And all these these these samples are taken off our GIs he's a different types of base maps, you can put. Steve Sorenson: On what your your subject matters, you can pick a base map that better fits which.
Steve Sorenson: There are some Apps again flat one dimensional limited expansion digital maps physically flat on your screen as well, but multi dimensional image expandable which are. Steve Sorenson: choosing a basement. Steve Sorenson: So you got a lot of selections but which 1am I going to choose and that's going to directly relate to what is the subject you are working. Steve Sorenson: Are you mapping logistics routes for a company or are you mapping demographics for business or for.
Steve Sorenson: Center for Disease Control are you mapping, economic or political demographics, these could all impact which base map you want. Steve Sorenson: So you have wide variety, the Nice part is you can. Steve Sorenson: You can pick and choose switching swap as you're going through you might start out with. Steve Sorenson: So you're doing an economic, demographic of an area of appalachia so. Steve Sorenson: you're looking at that just on the flat, where are the cities where the roads, the businesses you've got your different layers in there, showing the information. Steve Sorenson: or two like How does that fit with the terrain, the mountainous terrain does that have an effect so you switch from your flat street map to a terrain model and that can give you a different perspective on how.
Steve Sorenson: The train impacts, the economics, or the economic movement but ability in an area. Steve Sorenson: Based map should be reflective of the type of map information you're wanting to convey. Steve Sorenson: So now we come to building layers.
Steve Sorenson: So how many of you as a kid. Steve Sorenson: I hope this isn't dating and aging a bunch of people here. Steve Sorenson: Had a flip book. Steve Sorenson: Some little book and each page had an image that the image was ever so slightly different from the previous one. Steve Sorenson: and go ahead Lee.
Lee Rafalko: Now, does that area i'm old enough to remember that. Steve Sorenson: yeah so as as you flip the book flip through the pages, the image would move like a motion picture, which is basically what motion pictures are it's just a string of still images and the old ones, you can pull out the tape and you can see the individual. Steve Sorenson: stills of the the image on digital's now it's more of a fluid thing but. Steve Sorenson: The fundamentals still apply any at any point in that fluid stream, you can stop. Steve Sorenson: and select that still.
Steve Sorenson: So it truly is more like a football it just has a lot more pages. Steve Sorenson: So we're talking layers. Steve Sorenson: So i'm sure you're going where's he going with us so when we're talking layers that's what layers do is it's like your flip book on top of your map.
Steve Sorenson: Each layer contains different information. Steve Sorenson: And that information as its laid over each other layered over each other begins to paint a different picture, so you begin to understand better how things are relating and being impacted and affected. Steve Sorenson: So three basic types of layers are point layers which would be pin on a map or point on a map Polygon layers, which is a circle square multi sided.
Steve Sorenson: Order boundary and image layers which would be a photographic photo per metric image could be a lighter image could be a hand drawn in. Steve Sorenson: But you can put on an image. Steve Sorenson: So. Steve Sorenson: Importing images so when you want to you have an image and you want to import it into will say Google Earth.
Steve Sorenson: And if I didn't mention before I use Google earth, because a it's free anybody can get it and, be it covers the fundamentals and more we're trying to do with GIs so you can do all the fundamentals with Google Earth. Steve Sorenson: When you graduate to our GIs, then you can do all kinds of crazy stuff. Steve Sorenson: Okay, so when importing images, you need to ask yourself a couple of questions folks first one is what is the file format.
Steve Sorenson: that's kind of the. Steve Sorenson: Translated translator so we say you need you need to find what the lingua franca is and for you all people, you know, like me, you know what that means for the younger ones that's the universal language. Steve Sorenson: What is the universally understood language so with file format you just have to understand what the GIs will accept what format is it looking for and if it's not in that format for your images not you'll have to change that format. Steve Sorenson: so that it does The other thing you need to ask is does it include another there. Steve Sorenson: And the metadata is the location data tied to the image so without that it's not going to know where to put the inch.
Steve Sorenson: And then is his conversion request, so are you going to have to convert the file form. Steve Sorenson: So any questions on that stuff. Steve Sorenson: So images usually saved in one of several formats Google earth uses came out. Steve Sorenson: jpg is another common image format oC also PNG and tiff files. Steve Sorenson: And I think it's a jpeg or tiff might be tough is kind of the universal it's the one that's accepted by most systems very easily converted and imported in. Steve Sorenson: So common uses are common issues this one's a fun unfortunate I didn't have an example of an.
Steve Sorenson: Import your image, you know it has Meta data it's the right file form file format imported in it's supposed to go to fargo North Dakota and it ends up in Honduras, why isn't in hundred. Steve Sorenson: that's a coordinate system conflict, so the coordinate system of your GIs that you GIs is using is different from the coordinate system on the image, so you need to go in check the coordinate systems, make sure they match. Steve Sorenson: The other one is the images in the right location, but it's hovering over the earth. Steve Sorenson: like this one here if I was to turn this sideways rotate the earth you'd see that that's like 1000 feet above the ground. Steve Sorenson: Like probably more like 100 but.
Steve Sorenson: That is an elevation settings so you just have to go into the settings change the elevation level snap into the ground and i'll pop it right on the ground for you. Steve Sorenson: But those are some issues you'll see and. Steve Sorenson: relatively easy to correct. Steve Sorenson: Saving and exporting layers once you've created a layer Steve Sorenson: As you can see, this is on Google Earth. Steve Sorenson: you've got your layers so you will you right click on the layer and we'll go through this later on i'll bring up Google if.
Steve Sorenson: You right click on it it'll bring up where you're going to save it to but it give it a name and i'll say the camp Z or came out and you select which one you want it to save it adds. Steve Sorenson: Now candela's keyhole markup language it's a file format for saving it can see is just a zip form of Canada. Steve Sorenson: So. Steve Sorenson: And, depending on what system you're importing into some of them like ml some prefer kinsey's.
Steve Sorenson: it's just a matter of figuring that out when you important. Steve Sorenson: So, but then you make sure it's in the file format you want here and then you'd save it to whichever location wants it. Steve Sorenson: And then, when you import it into a GIs you can either some systems legend click and drag others, you have to basically do a file drill down through the system to go get it it'll have you search for it and pull it in that way.
Steve Sorenson: So saving layers. Steve Sorenson: Questions to consider when you say why are you saying, for what purposes of being saved because that may determine what format you save it in where you save it to those things you'll need to consider when you try to save the layer Steve Sorenson: and obviously the system you're saving the layer into core for you, so if you're producing something for somebody else. Steve Sorenson: And you want, you can send it, you can just email Nick html or the camp Z but are they going to be able to import that or are they going to have to change the format. Steve Sorenson: Before they put it into the system into their system, so you, depending on what your working relationship is with them, you may want to change it to the format, they need before you send it to them. Steve Sorenson: Which leads us to system interoperability, so there are several systems out there, I just got a couple of them up there. Steve Sorenson: And in order to try and get them all to talk to each other, you have to understand what formats, they need and use because they all use different words.
Steve Sorenson: or prefer different once. Steve Sorenson: You think from our roadmap to our product our online it be easy it's all the same system right, not so much. Steve Sorenson: They have tools that you can save the formats, to move it to another ones, but you can't just save and instantly important.
Steve Sorenson: So here's some of the different. Steve Sorenson: Requirements Google Google earth pro works with cam Allen jpg you pretty much just click and drag them in. Steve Sorenson: Our earth imports kales easily, in fact, you can take a Google Earth. Steve Sorenson: cam House I just directly click and drag them right into darker. Steve Sorenson: Our map, because the tool conversion from can help to shape up. Steve Sorenson: In our pro requires a tool conversion from camel to shape.
Steve Sorenson: The and our gun line that would require the file format to be a shape file csv file a GPS or a geo json. So. Steve Sorenson: So that's what they need in order for you to bring them in. Steve Sorenson: Unfortunately, we won't be working with all those so spatial relations, which is, how does the subject relate to its environment. Steve Sorenson: What is the impact of the subject on the environment was the impact of the environment on subject out of the influence each other if at all, and what are the effects over time.
Steve Sorenson: Is it a one and done thing like it just has this initial impact and that's done or is this an ongoing eternal thing. Steve Sorenson: Is it going to keep keep having residuals forever and ever. Steve Sorenson: And he question. Steve Sorenson: There being none practical exercise time.
Steve Sorenson: So. Steve Sorenson: Using Google earth pro. Steve Sorenson: create an imagery product using utilizing point Polygon and images.
Steve Sorenson: And imagery layers. Steve Sorenson: So. Steve Sorenson: you've got those those sure i'll be in the download. Steve Sorenson: For understanding GS.
Steve Sorenson: and your product is produced product that defines the boundaries of North and South Dakota I think too easy states. Steve Sorenson: and identifies their capitals and displays tribal boundaries, as represented in the 1851 Treaty now. Steve Sorenson: So you say holy cow. let's. Steve Sorenson: bring this down. Steve Sorenson: and bring up hulu Earth.
Steve Sorenson: Okay. Steve Sorenson: So. Steve Sorenson: Oh, and if you press the power button on your keyboard it rectify is the world so turns it to north. Steve Sorenson: And you're back there, so you get alternate around just remember just hit are.
Steve Sorenson: No rectified so. Steve Sorenson: What you did the trace the boundaries, you can do that one of a couple ways. Steve Sorenson: And then identify the state capitals of the to Bismarck and Pierre case you didn't know i'm sure you do so. Steve Sorenson: But before we get to that. bring up.
Steve Sorenson: Firms here. Steve Sorenson: A couple different things. Steve Sorenson: Okay, so there's a 3D map.
Steve Sorenson: The travel boundaries and shows present day wyoming. Steve Sorenson: Probably use them. Steve Sorenson: So what we're going to do on that. Steve Sorenson: First of all, identify the capitals, because that's easy the Meta data in a layer Steve Sorenson: is usually contained in what is called an attribute table and the attribute table and most things as a csv comma separated value excel document. Steve Sorenson: And that will. Steve Sorenson: That will give you.
Steve Sorenson: The. Steve Sorenson: Data you need to place. Steve Sorenson: Please, the. Steve Sorenson: capital, and this is what it looks like the basic model. So.
Steve Sorenson: yeah to be table. Steve Sorenson: He doing one of a couple of things, so it pretty much always has an object ID. Steve Sorenson: which usually number 1234 shape this will be a point shape.
Steve Sorenson: Name so Bismarck and Pierre. Steve Sorenson: And then you have the latitudes and longitudes this would be the. Steve Sorenson: That is the. Steve Sorenson: latitude and why is the longitude Z is for elevation So if you had something you're really bringing in that had a specific elevation you could put the Z factor in there and it would.
Steve Sorenson: Add that to that this putting this information in. Steve Sorenson: You can save your excel document. Steve Sorenson: As soon as. Steve Sorenson: This is the excel. Steve Sorenson: You save your excel as a csv so you just do a file save as. Steve Sorenson: And click on the drop down here and choose, yes, this one is this is.
Steve Sorenson: that's What do you do you just go down find csv tears when they click on that save your excel as a csv. Steve Sorenson: Then. Steve Sorenson: All you need to do is you can click and drag that excel into a csv into here, and it will populate. let's see. Steve Sorenson: A little bring this up now, you say yeah it's the limited comma. You know.
Steve Sorenson: To checking point there's more latitude longitude. Steve Sorenson: latitude longitude. letter to field. Steve Sorenson: If I got those mixed up and and put them in the wrong order, what would happen. Grant Onokah: Anyone could hold the one location yeah.
Steve Sorenson: They would throw me out and eastern Uzbekistan, or something so yeah he'd be. Steve Sorenson: Be not where you're supposed to be. stream.
Steve Sorenson: Okay that's right, so if it's a number it's an integer if it's a bunch of numbers or words it's a straight. Line it's in sounds. It works yeah.
Steve Sorenson: right there right there. So put it on there. Steve Sorenson: As you can see here.
Steve Sorenson: and stop them down but it didn't give him a name, so now, you can go in and name those individually. Steve Sorenson: Or you could put a column in your attribute table. Steve Sorenson: That would give it a name, so when you populate this and come up, and it would say Bismarck and say Pierre there. Steve Sorenson: So we have those that's how you make those those dots they're building that the table. Steve Sorenson: But you can put another one on, though, if you want to put grand forks on there, which is up here or as a rapid city down over here, you could add those to. Steve Sorenson: Just find their latitude longitude or.
Steve Sorenson: The other thing you can do. Steve Sorenson: Is. Steve Sorenson: You can do it instead of latitude longitude you can do it by address.
Steve Sorenson: So all you need to do is put the street address on there. Steve Sorenson: And it'll do the same thing. Steve Sorenson: It will put it in the proper place when you drag it in so you can do it either way, so if you are like. Steve Sorenson: Trying to map out where all your relatives. Steve Sorenson: You could just put their.
Steve Sorenson: Their address you wanted to put the names, but the nature, you just put their street address or just their city or just their zip code. Steve Sorenson: And it would put a pin on that map we told it to put the point. So. Steve Sorenson: Now any questions on. Steve Sorenson: had to be tables at point layers. Archie Williams: Have a quick question.
Archie Williams: i'm a new new person to this, so if I was say making. Archie Williams: a map of different farmers and co op. Archie Williams: Okay, where where would I say with with this map be available to Google maps or where would it be a say an external matt did they can pull up between themselves, they will be stored on a server somewhere, how would you do that, or is that possible. Steve Sorenson: Yes, as ever, gets. Steve Sorenson: It all depends on how you say that you would create it and it's that's a good point because it when we get into talking about park online and stuff there's different storage. Steve Sorenson: issues and terms, so, but with Google earth if you created it your home you created this map of the farm or the whole all the farms of the call.
Steve Sorenson: You can save that you could and that's where it comes into data management, how you want to save that. Steve Sorenson: i'll kind of give you a crazy idea here see if I have. To do.
Steve Sorenson: Is we're doing a project for local solid water district we're flying all the county ditches. Steve Sorenson: So these are the ditches so interpolate this, as these are ditches for me, but maybe that's farms in your car. Steve Sorenson: Okay Okay, so that could identify all those now for your data management, when you pull up your file. Steve Sorenson: Get basically you want to you want to establish your data management structure. Steve Sorenson: How you want to utilize it, or whatever you doing this for say you're doing this for the co op how the Co op wants ordinance do they want to maintain that database and if they do, then you can under the co op. Steve Sorenson: server because you probably need a server for all the data.
Steve Sorenson: And imagery. Steve Sorenson: So under that you could have a folder like we have points here, you could have a folder for each farm and under that farm you'd have each of the products you've produced for that farm. Steve Sorenson: Oh, that could be depending on how you set up your privileges and access to the data that could be available to everyone, or that could be available to that farm only. Steve Sorenson: The people in the co op that that manage that, and the individual farmer, because I know farmers, at least up here they're really picky about letting their information out right yeah they don't want to let the other farmers know what to do. Steve Sorenson: But but that's how you can you manage that and then how you want to manage the products underneath that for that farmer or your file structure everything that's all up to you what works best for your. Steve Sorenson: Your system your company that's what you would you would probably want to do in in a thing I did you could map out, you can do a point like these.
Steve Sorenson: Either do a point to where the the farm is. Steve Sorenson: So you could have a map with a bunch of dots on here to show all the farms that are your core, but then on each of those files for that inside that file, you could have field boundary maps for. Archie Williams: Okay. Steve Sorenson: auto steer programs or application maps that you've done, for we projects or fertilizing projects on that specific farm and you can even separated by crop. Steve Sorenson: So what What did we do last time we grew our last time we grow soybeans.
Steve Sorenson: We apply stuff so that's how you can manage that, and a lot of this. Steve Sorenson: kind of the drudgery side that nobody wants to deal with a talk about, but the data management is a big thing if you if you don't set up your data. Steve Sorenson: With naming conventions and proper format it's a nightmare trying to find all your information, so that you have to does this stuff follows. Steve Sorenson: It will bring that up here. Steve Sorenson: So.
Steve Sorenson: give you an idea. was my hard drive. Steve Sorenson: See if it'll go there.
Steve Sorenson: go there. Steve Sorenson: I have to fight the bandwidth of the whole College first. Steve Sorenson: So bear with me. Steve Sorenson: But you'll see this directly applies to Okay, so we keep our information and viral. Steve Sorenson: Using air quotes here I borrowed this from our GIs this format and in base map data set shape files it, for me it works very well. Steve Sorenson: data sets, is where we keep all the information to base maps is your base map for your project file.
Steve Sorenson: But data sets. Steve Sorenson: So, as you can see, here we have flight dates. Steve Sorenson: But for each of the ditches we have five. Steve Sorenson: And then within that file we find one oh, we got a lot of stuff in. Steve Sorenson: Looking at this one.
Steve Sorenson: So. Steve Sorenson: Within that file we've got organized by flight dates So these are days we've flown those fields are that ditches and then. Steve Sorenson: Say for here. Nothing. Steve Sorenson: But you can see, on the navy naming Convention it's in the grants folder under the project.
Steve Sorenson: Is in the data sets folder under the ditch the date flown very short but descriptive names for those folders. Steve Sorenson: So I know exactly where the drive down. Steve Sorenson: Then we ran into that problem with fields, because we were naming the fields by the. What is it. Steve Sorenson: Section track. Steve Sorenson: range.
Steve Sorenson: And the name started getting exponentially huge for these files, so it got to a point where the fear of saying nope that names too long i'm not going to go there, so we had to shorten it up, and so you have to keep an eye on that too, but what this should be showing you is what we flew. Steve Sorenson: That so we provide our that the sunlight or folder. Steve Sorenson: Then within that folder or the products so let's the light our products, we did a digital elevation model raster of it, and we did contours for them. Steve Sorenson: Okay, so, then you know what you're looking at as you're drilling down into it, you can see what you're doing so that's you need to come up with a file structure that works for you for that project and then bring that in. Archie Williams: Thank you. Steve Sorenson: No problem, so what we're looking at here, then.
Steve Sorenson: i'm doing that outline for, for it is effect here hey this would be a place marker or point marker so in Google you just hit that and it brings up a properties window, but it also gives you your marker to move that all over the place, so I could like put that there and go. Steve Sorenson: Even. Steve Sorenson: Grand forks. Steve Sorenson: And click on that change color. Steve Sorenson: All that fun stuff the also noticing the properties it tells you the latitude longitude. So.
Steve Sorenson: Okay okay i've got a point on the map so that's the manual way but. Steve Sorenson: If you want to do a line. Steve Sorenson: Like say I wanted to drive from. Steve Sorenson: fargo to grand forks. Steve Sorenson: And click on fargo. Steve Sorenson: And I can keep doing points along the way.
Steve Sorenson: You know if I want to change a point to go back and click on it and change it. Steve Sorenson: You should come back here, otherwise they'll tell you out, so I can do that route continue that route on and it'll draw a line for me. Steve Sorenson: In a Polygon is the same thing only it's just a Polygon so I wanted to say, draw a circle around fargo here. Steve Sorenson: To my Polygon. Steve Sorenson: And I can click to get the points.
Steve Sorenson: Or if I wanted to quickly. Steve Sorenson: click and hold it down and then you can just draw. Steve Sorenson: But as you're moving your cursor it's putting down a bunch of different points So you see you got the point gaps here, and then you have a bunch of points here when you zoom in. Steve Sorenson: You can change any one of those points drag it out push it in, however, you want to adjust it.
Steve Sorenson: To make it, but then that gives you the Polygon. Steve Sorenson: which you can also do with that is. Steve Sorenson: You can change your opacity.
Steve Sorenson: So say I don't want it, that colored in, I only wanted it like 30% so now, I can see through that layer Steve Sorenson: So you can kind of highlight your area and still be able to see the map underneath. Steve Sorenson: So that's what you can do there. Steve Sorenson: So when you trace the exercise when you're tracing the state boundary. Steve Sorenson: it's about literally all you have to do is click on the Polygon.
Steve Sorenson: Make your points and then, if you wanted to do the tracing just going to do the trace. Steve Sorenson: The just come back to set it down there is North Dakota and you can adjust your capacity to how you want it. Steve Sorenson: But that's basically the easy way to trace around that now, if you wanted to get in there saying, I want to be.
Steve Sorenson: Exactly on this river the River path here because that's the eastern boundary is the river, then you can go in and adjust each of those little points over to match exactly river. Steve Sorenson: So all depends on how detailed you want to get. Steve Sorenson: But that's how you can do that on the on the points, since I gave you.
Steve Sorenson: The cities that you want to add, you know, a city or two in north or South Dakota to list and just import them in that way, see how that works for you go ahead and give that a try. Steve Sorenson: And then for. Steve Sorenson: back to the other documents there's the. Steve Sorenson: Treaty boundary. Steve Sorenson: Which i'll take the blame for.
Steve Sorenson: me just catching up with me. Steve Sorenson: So we have we. Steve Sorenson: Do. Steve Sorenson: For learning so as you can see. Steve Sorenson: You can see the I haven't saved here is the map that's just the image, so what we want to do is it's not do a reference. Steve Sorenson: So how do you get a non GMO reference into a geo reference.
Steve Sorenson: it's made. Steve Sorenson: You go over here to this this. Steve Sorenson: image overlay. Steve Sorenson: Now the trick to this is your overlay has to be. Steve Sorenson: somewhat the size of. Steve Sorenson: What your input so.
Steve Sorenson: Where important this. Steve Sorenson: So it should your map underneath here should be roughly zoomed into the size of this. Steve Sorenson: Otherwise you're going to be tweaking a lot so. Steve Sorenson: I want this to be a little bigger. Okay, no. Steve Sorenson: image.
Steve Sorenson: click and drag that image here. Steve Sorenson: that's it. Steve Sorenson: So now what you'll notice is again we have the capacity, but now it's a slope.
Steve Sorenson: that's really next. Steve Sorenson: So what we're looking at is there's wyoming. Steve Sorenson: And there's well. Steve Sorenson: So the green outline this controls, how you can shape the image, so you clicked on the Center you can move the whole thing around so if i'm looking at wyoming there.
Steve Sorenson: There so i've got that corner and while we pretty much set. Steve Sorenson: Now if you're going down to the corners here. Steve Sorenson: Just like a lot of other things I can squeeze it in I can squeeze the whole thing down a little.
Steve Sorenson: I can take click this here and rotate. Steve Sorenson: So we're going to try squeezing right now. Steve Sorenson: And i'm going to set about latitude longitude as i'm moving my cursor you see how the latitude longitude change, as well as the elevation. Steve Sorenson: So if you're looking for that data when you're dealing with. Your slides.
That can help you. Steve Sorenson: move down a little. Steve Sorenson: shapes it up. Steve Sorenson: Okay, so that roughly.
Steve Sorenson: fits on there, so now. Steve Sorenson: demon. Do. Steve Sorenson: Okay, and when I save it it's going to save it as a layer over on the side.
Steve Sorenson: So i've saved that. Steve Sorenson: shows up over here on your left hand side. Steve Sorenson: As a layer of I want to save that. Steve Sorenson: Save place as. Steve Sorenson: it'll ask, we can see.
Steve Sorenson: My want to do it as cameo. Steve Sorenson: Where do I want to put it. Steve Sorenson: So this is currently in downloads but now I want to put it here.
Older. Steve Sorenson: Okay, so i've saved that but what does that do for me okay great I have it on here Well now, as you can see, when I zoom out zoom in it stays stuck to where it's supposed to be. Steve Sorenson: So if i'm looking at this map.
Steve Sorenson: and Steve Sorenson: I want to know what's the Center of the Su boundary here going to go to where the Center is now, I know, with a Jew geographic Center because I can see the lat long I can record that oh it's right there. Steve Sorenson: or where's the Center of the black hills. Steve Sorenson: What would you can also do.
Steve Sorenson: You knows. Steve Sorenson: Since I have that there I saved it now, I can export that someplace else, so if I wanted to send that to somebody I could send it out. Steve Sorenson: And they would have that map and could pull it into their GIs and bang they've got so we both done essentially GEO referenced a non GEO referenced image and that's what you that's how you do that. Steve Sorenson: Another way of doing that would be finding key. Steve Sorenson: control points in it.
Steve Sorenson: Like river junctions you could mark the geographic location of each of these river junctions here. Steve Sorenson: and use those as control points to adjust your image. Steve Sorenson: A little more difficult. Steve Sorenson: yeah. Thomas Biller: Paul has a question about what what kind of computing power do you need to efficiently work with average size multi layer model.
Steve Sorenson: I would say. Steve Sorenson: You bigger things are processor size and zach might be an answer this one, a little better than me but processor size Ram your storage. Steve Sorenson: and Steve Sorenson: Your graphics card so generally easy response to that is a medium medium to high grade gaming computer. Steve Sorenson: Because sounds kind of funny the gaming computer what they'll because they have the high speed graphs. Steve Sorenson: So that's why it's easier to if you go with a gaming computer than the graphics are already there are pretty much up to speed, you can do this and that's what's going to happen when you're dealing with imagery a lot is your graphic card really needs to be set up for them on our website. Steve Sorenson: For college didn't pull it up.
Zackary Nicklin: This DVD from this link i'll just chime in a little bit here. Zackary Nicklin: So typically what you want to do is you want to match it to the software that you use now when you do a lot of great photo grammar three things like that you know you're looking at JAI Ram. Zackary Nicklin: Multi multi core and multiple threads cpus but each individual software package, whether it's PICs for Dr archie is things like that. Zackary Nicklin: If you go into their about information they should have a recommended setup and that recommendation is typically minimum so anything above that gets you know gets you more bang, for your buck there you gotta draw the line for yourself where your your financial ability meets your needs.
Steve Sorenson: So here shameless plug for our programs. Steve Sorenson: But on our website. Steve Sorenson: If you scroll down towards the bottom.
Steve Sorenson: There is a pistol right here program specific requirements specific computer requirements. Steve Sorenson: click on that that'll bring you to our sheet, this is what we use as a baseline for our students, you need at least this. Steve Sorenson: to function online, because the systems we use the software to use utilize this much so, if you're going to be doing programming you're going to want to be looking at this in particularly the recommended way down here 64 gig of Ram. Steve Sorenson: You want high speed Internet connection, especially if you're pulling stuff down from the. Steve Sorenson: cpu you want an eye seven, at least, and then video and depending on how how intensive graphics you're using that gpu will change, so you want instead delicate dance that we all. Steve Sorenson: How much graphic can I get for how little money.
Steve Sorenson: Because we all want to save money, but it's if you're gonna if you're going to save money into stuff the gpo would be one of the things to sink into. Steve Sorenson: Any other questions. Steve Sorenson: Okay, so now that we've GEO referenced this we've got that. Steve Sorenson: got that available so The other thing too is off of this say you wanted an independent layer Steve Sorenson: To show just the same just the blackfoot reservation, so you could go in and draw that trace that around like we did for North Dakota there trace around on it, and then you would have that boundary. Steve Sorenson: ruffling or you could do it the long way, which I did. Steve Sorenson: and go to the Treaty and actually read the description which is kind of a metes and bounds thing if you've ever done real estate descriptions.
Steve Sorenson: It tells you from this point to this other point from there to another point so you're basically finding points on the way, and then you connect the dots along the description that they give you. Steve Sorenson: So that's the other way of doing it. Steve Sorenson: And what you get when you do, that is. Steve Sorenson: Lisa bring it up you actually hear. Steve Sorenson: you end up with this.
Steve Sorenson: Which. Steve Sorenson: turn off the. Steve Sorenson: Take that and you to move them down here over here so as you're trying to. Steve Sorenson: assemble your stuff see put that into that folder so here's already talking about the farms and how you're going to manage that.
Steve Sorenson: So yeah you could have the Co op folder each of the farms is listed in separate folder here that within each of those folders is the individual information from hands, so that way you can access that you can turn on one farm at a time. Steve Sorenson: So here we have that boundary So if I turn off this map. Steve Sorenson: that's the boundaries based on. Steve Sorenson: The description in the Treaty. Steve Sorenson: And then here's the math they have welcome from treating.
up here. Steve Sorenson: Okay, so there's the map, so you can see underneath the map, you can see the traces and it's pretty close to what they got there. Steve Sorenson: So that's how you can figure those out. Steve Sorenson: And do traces on that. Steve Sorenson: or create your own.
Steve Sorenson: But the other, the purpose of doing stuff like
