Location and size of India v2

Geography
In this recording, we're going to use the ArcGIS Geography visualizer, which is a GIS application, to visualise the location and size of India. And, now on the visualizer, we can see at the bottom, this toolbar, we've got something called Basemaps, and that can change the basemap that you can see. And at the moment, this is a world imagery map, which is just physical geography, and the problem with this is we can't see the country borders on it. So I'm going to change this. I've clicked on Basemaps in the bottom toolbar. I'm going to change it to a Charted Territory Map. There's different ones we can use, but I think this is going to be useful for us because we've got lots of geographical reference points, like lines of latitude here. I'm then going to cross this because we don't need that for now. And if I wanted to, and if I couldn't find India, I could use the magnifying glass in the top left-hand corner and I could type in India. However, I think we can see India, can't we? it's in the middle of the screen. And using this map, it allows us to describe the location of India. And a good thing about this map is it's got lots of reference points we can use. So here we can see the equator, so I can say that India is north of the equator, is in the northern hemisphere. I can see that the Tropic of Cancer runs through India. So I can give geographical reference points using lines of latitude. I can also, because the countries are on here, I can also talk about which countries border it. So we can see that Pakistan borders India to the northwest. If I zoom in, I can see that this is Nepal, bordering it to the northeast. We've got Bangladesh to the east here. And actually, if we look at India, we can see that it's actually got this territory right the way to the other side of Bangladesh, so we can see that India also borders with Myanmar, it has borders with China, it has borders with Bhutan. Now, you may think we can actually also think about the size or visualise the size of India by just looking at this chartered territory map and comparing it visually with other countries. Maybe looking at it relative to the United Kingdom, or let's look at it compared to Greenland. Well, maybe India looks like it fits into Greenland, you know, four times or something. However, there's an issue with this, and the issue comes with changing a spherical object like a globe and trying to project it onto a 2D surface, a flat map. And we can do that in lots of different ways, but every way we do it, it slightly distorts the map. Often it makes things bigger or smaller or changes the shape. And it depends on which projection we use as to how the map will look. Now, on this map, this is based on the Mercator projection, and we can see that Greenland looks absolutely huge on here. India, it looks relatively small. But a good way of checking that is to use this measuring tool, and its measuring tool is in the bottom toolbar. So I'm going to click on this, and I'm going to click on Measure. And in this measuring pop-up, I'm going to click on where it says Measure Line. And I now need to go over to Greenland, so what I'm going to do is I need to pan over to Greenland, so I'm going to hold the left button of the mouse, I'm gonna hold that down, I'm gonna drag the screen across, and we can see Greenlands there. And it looks absolutely huge, doesn't it, in comparison to India. So, because I've clicked this measuring line, I can click on the north of Greenland, and what I'm going to do is I'm gonna change the unit to metric, to keep it in kilometres, and I'm gonna take it to the south of Greenland. And you can see there, it's about 2,616 kilometres. If I want to double-click, it keeps that there, so I can then move the mouse and it'll stay there. So, okay, I'll make a note of that. It's just over 2,600 kilometres. I'm now going to pan over and we're gonna compare that with India. India looks so much smaller, doesn't it? So much, so I'm going to zoom in and I'm going to do the same here. So I'm going to do a new measurement, which will take that old measuring line away. I'm going to click on Measure Line. Now, a complication in India is, you can see these red dotted lines in the north, and this is disputed territory around Kashmir. Different countries claim this land. So we're just going to go just to the south of this dotted line here. I'm going to click on it to start the measurement. Again, we're back in imperial, so I'm going to change that to metric. I'm going to come to the south of India, I'm going to double-click on it, and what you can see, 2,765 kilometres. Believe it or not, India is actually longer north to south than Greenland. And if I zoom out, the measurement will have gone away because I've done a new measurement, but you can see just the difference in how they look. But the measuring tool allows us to actually focus on the reality by giving us a really clear distance in kilometres from north to south. So that measuring tool is really useful for being able to compare the sizes of countries around the world.
