[MUSIC] Hello again and welcome back. In this lecture, I'm going to show you some different tools you can use to manage the symbology of your data in [INAUDIBLE]. I'll show you how to import symbology, save out your symbology, so you can reuse it, and then how to copy it between layers. As an example, I would like these layers down here, to mimic the colors and styling, in the layers on this map here. They're the same geographic layers, but maybe I've added the data to a new map document, I lost the original symbology from my map document, and I want to bring it in from an external source that I have. So, I'll show you how to do that, and then I can also copy the symbology from these layers to the layers that are up here. On a practical note, I've provided in the map package not just the map document and the layers, but the map package will extract the layer files in, but it's going to extract the files I'm going to use to a location in your user folder. So in my case, that's c colon backslash users, slash this name here. In your case, often times Windows puts your user folder in quick access. It'll be your name or something like that. And arc j s stores files in your documents folder. And then in Arc GIS, and then it extracts the map packages to the packages folder. So you go there and see all the map packages you've used. And then in the folder for this one, which is an AV 1021 L9.5 copy and savings you can open that up, and under common data, under user data, buried all the way in here, are all the layer files we're going to use. So when you're working with it on your own machine, that's where the data you can use to replicate what I'm doing on the screen is. Okay, let's bring this back up full screen here. And to start with, I'm going to load in the symbology that I'm going to use for this layer. I can set it the way we always have, using the symbology pane. But I can also go to our properties, and under symbology I can go to import up here instead of setting it directly. And I can leave it as import symbology definition from another layer in the map or from a layer file, and I can go to browse And I'm going to paste in that path. But navigate to the folder that has all that symbology in it or all those layer files I just showed you, so in your documents arc GIS packages folder. So I'm going to hit enter, and in this case this is Extant. So I saved out a mean range map's Extant layer file. And it's not a layer package, it's a layer file, and layer files really just have the symbology definition. So if I click add here, and then layers likely present. I click okay, it sets the symbol to this orange. I can click apply. You click okay. And there's not a whole lot of it down there, but let's zoom in. And it looks like it's getting covered up, maybe. So if I turn that off? Yup, it's covering up. So let's import that one next. So we go to properties, Import. I'll go back to the browse here, and I'm in that folder still, so I'll go to historical, which is the one I want for this one just let it do as quickly historical, and I'll click add and then okay and then okay and I'll get that cross hatching that was in the map, and I'm going to do the same for the rest of these two. So I won't narrate as much, but the observed layer, import, and observed. Set those polygons to a kind of red-ish orange now. And then I have these two translocated layers. So their properties, import this one is translocated observed. So I'll choose that one. Click okay again. It's a lot of handwork, but it's much faster than trying to replicate this style directly from something else. I don't have to worry about getting the colors exactly right by going through the color palette or something like that. And so then this last one is the translocated expert. So click Add, and then OK, and then OK. And now I have something close to that map or rather that particular map that I exported. I have similar symbology to that one. One right here in this map now. Okay. Well, what if I want to copy that symbology over to these other layers, and maybe I had then in the same map document, but I didn't actually have a layer file anymore? Well, I can do the same thing within one map document. So I go to properties Instead of going all the way out to the layer file, I can go to import, and I can just from this layer drop-down, I can select where I want to import from. So, I want to import from the historical expert layer here, to this other historical expert layer I'm looking at. I'll click OK. And that changes the symbology of one of the layers here, let's expand this out so you can see. So, we can import symbology from layer files, and then we can import it from other layers in the map document, as well. So, I'll do that again, import from the other layer in the map document. I want to import from the observed thing here, so I'm importing observed. Click apply, OK, and then I'll do it one more time for the [INAUDIBLE] here. Okay, so I just copied the symbology from one set of layers to another without going up to the layer files. Well the last thing I can do is I can go modify one of these layer's styles. I can modify the symbology. And then I'll save out a new layer file, so I can reuse it in another map document. So I'm going to go to edit symbol. Maybe I want to change the separation between these lines. And we've mostly just dealt with outlines and fills, but there is a whole huge symbol property editor in IJJS. I can add another layer here. Maybe I could change the layer, the separation between these cross hatch lines, or maybe I'll change the angle on them to 35 degrees, and I'll change it to 9 degrees, or 9 points of separation. And we can also add another another one. Let's do negative 35 degrees, and I'll leave it as not super thick lines and 5 separation. I click okay, and we get a different sort of cross hatching on that, and it's a little hard to see so maybe we'll go clean it up a little more. And change the separation on these to something much larger. Let's try that. It's a little better. It's still difficult, but we could say it's good enough for the demo. And what I'll do at that point is I'll save as layer files. So there's create layer package and save as layer file. And I'll save it out as a layer file to that same folder that we were in before. And I modified the historical one, so just for my own record keeping. I don't have to name anything particular, but I'll do I'll call it a cross hatch, so it's a cross hatch modification of the original historical lines here. And that way I can save it out, and I have a version for myself that I can then go import into another map document if I want. And if I take a look in this folder that has the layer files, they're much smaller than I'd expect from a layer package. That's one other is I wouldn't expect that I can get all this geographic data into 10 kilobytes, instead it's really just a bunch of information, and if I was really going to have the data it'd probably be a couple megabytes, because it has all the feature information, all the vertices, all the edges, all the attributes. So that's one reminder to you that layer files are not layer packages. They're very different beasts that performed different functions. The other thing to look at is, the one that we just exported, is significantly larger than the others. And I'd imagine that due to the complexity of the symbology, just that It's not just, here's a color, and then here's an outline with an outline color. It's line spacing, it's angling, it's colors, it's all of those things that make up a complex crosshatch symbol like this. Just like I can share layer packages, I can share layer files with people too. So I can send off layer files, and people can use them as their symbology. Doesn't have to be applied to this particular data. I can create a new feature class, a new polygon layer and import this symbology directly on to that too. The only limitation is that it needs to be the same data type. So if I export point symbology as layer file I can import to points. If I export line symbology to a layer file, I can import it to any other line feature class. And the same thing with polygon layer file. If I export polygon symbology, I can import it to any other polygon layer too. One thing to note is that if I was symbolizing on an attribute here, so we go to properties, maybe let's change our symbology to something like quantities here. And I'll symbolized by size here, and I'll use that default that we've been using for the income ladders, so to speak that we've been using for these others as the attribute to symbolize on. Well if I want to copy it over to another feature class here, if I go to import, and then I import it from the historical expert one that I just modified, this one here. It's going to prompt me for which one is the same value field. Even if it has the same name, it's going to confirm with me, that the field I want to use is the same name. Or if it has a different name, it's going to ask me to choose which field in the feature class has the values that the symbols are based on the feature class we're importing from. So i'll select acres, click OK, click apply, and that one updates, too. If I turn this off, I can see. Okay that's it for this lecture. In this lecture, I showed you how we can manage our symbology data by exporting our symbology to layer files, importing from layer files, copying between layers in the same map document. And choosing the attribute that we're symbolizing on when we're importing from another layer or layer file. This also wraps up our segment on symbology. We could do so much more on cartography and symbology, and deciding what to show you was pretty difficult here. We originally wanted to do a full class on this, and maybe we will some day in the future, but for now this is about as map styling that we're going to show you. I encourage you to dig around and find more. There's all sorts of stuff you can do here. Especially if you take a look in symbol editor I was showing you. If we go to the features and click here and go to edit symbol, there's a whole lot you can do if you select different symbol types and start adding layers and, and more. The most advanced cartographers are very good at using that symbol palette. Okay, see you next time.
