In this video, we're going to use the RGIS geography visualizer to investigate the location and size of Nigeria. And the first thing I'm going to do here is I'm going to change the base map. So I'm gonna come to the bottom tool bar, and I'm going to click on base maps. And I'm gonna change this to a chartered territory map. And the reason I'm going to do that is it essentially takes away a lot of the physical geography information, and gives us a political map, showing really clearly the countries and their borders. We now need to find Nigeria. So I'll close the base maps down. Now I could search using the search button in the top left hand corner, and type in Nigeria. But as you may be aware, Nigeria is in West Africa. So we can see Africa kind of in the centre of the screen. And we can see Nigeria just here, kind of right in the centre, and I can zoom into that if I like. Now the useful thing about the chartered territory map is it's got some geographical reference points. So what I mean by that is things that we can use to help us describe the location of Nigeria using directional or geographical language. So we can see the equator, for example, running along around the world here. And we can see the position of Nigeria is just north of the equator. We could maybe use this information that we can see, we can see that Nigeria's in West Africa. And it's essentially between the equator and the northern hemisphere, between the equator and the Tropic of Cancer. Now, you may think that a good way of looking at the size of Nigeria, or thinking about the size of Nigeria, is just to visually look at it. So, you can see the size of Nigeria here, and maybe we could compare it to another country like France. Looks about the same size as France there, doesn't it? And we could compare it to the United Kingdom, and look at it. The United Kingdom looks a bit longer north to south, and it's significantly longer north to south but a bit thinner. However, there is a real problem with that on these maps, and this is because map projections tend to distort the size of countries north to south, or east to west, depending on the type of map projection it is. And the reason for that is it's very difficult to take a sphere, like the world, and project it onto a 2D flat surface. And now this is based on locator projection and it does distort the size of countries quite significantly. So we've got some useful tools in the geography visualizer to help us navigate this issue. Now, one of the most useful tools to do this is what we call the measuring tool at the bottom. So if I zoom in a little bit and click on the measure tool, and then I'm going to click on measure. And you can see a little popup comes up and can see measure line, measure area. I'm gonna choose measure area. And if I zoom into Nigeria, what I can do is I can click around the border of Nigeria and start to put the area together. Now, I'm gonna do this quite quickly. I could zoom in and really take a lot of time going on every slight change in the border of Nigeria, but I'm going to do it relatively quickly here, just to give you idea of how we do it, and give an approximation of the area of Nigeria. And I'm going to double click there. Now you can see that that's in miles. If I change it from imperial to metric, I get a figure in kilometres. And you can see there, that's just over 898,000 kilometres squared. So that gives you an approximate area. I appreciate I haven't done a perfect line around the border, but it gives you an idea. Now, what we could do then is we could maybe compare that with another country. So as you can see, France looks quite a bit bigger than Nigeria here. But let's check to see if that's actually the case. So if I go onto France, and again, I'm gonna give an approximation, the area of France, I'm not going to do it exactly. Zoom into that a little bit more to make it a little bit easier for myself. And just go down this border, and we go around France. There we go. And what you'll see there, you can see on the screen, this figure is 536, just over 536,000 kilometres. Now that is significantly smaller than Nigeria. Now the area will have gone off Nigeria now, and if I take this off, you can see the issue with these maps. Nigeria looks smaller on the map, but it's actually significantly bigger. And this is an issue around countries close to the equator if we use the locator projection. They are actually a lot bigger than they look on this projection.
