0:00 ranking almost every map projection episode one. So we are going to start the series with probably the most popular map projection in the world and
0:08 that is the merkar projection. Now the merkar projection is a conformal cylindrical map projection. Conformal means that the angles between two lines
0:19 or curves stay the same even though it is on a flat map. And a cylindrical map projection essentially means that a globe was mapped to a cylinder. So the
0:28 Mercer projection is really good at marine navigation. This was actually the main reason it was created in 1541 by Gerardis Merkar. This is because a rum,
0:40 which is a curved line that maintains a consistent angle, appears straight on the Merkar projection. And this is helpful in marine navigation because you
0:48 can draw a straight line between two points and that will be the angle that you have to set your compass to to follow. The Mercer projection is also
0:56 the primary projection that is used on websites such as Google Maps, Open Street Maps, and other websites. And the reason it is commonly used on these
1:04 websites is because it is very easy to tile and in smaller scales, it maintains a constant scale to areas around it. However, as you probably know, the
1:14 Mercada projection greatly distorts land area. And this is because the latitudes get stretched out the farther away you get from the equator because of how
1:24 mapping on a cylinder works. And so places like Greenland, which appear as the size of Africa on the Mercer projection, in reality are a lot
1:33 smaller. And so with all of these things considered, I'm going to put it at B tier because the scaling is really bad, but it is also useful for navigation and
1:43 it is and it is basically used in all mapping services.
