Today I'm here to help my friend Sarah learn about map projections. Oh look, there she is!
Hi Pat! So what are map projections? How many are there?
Map projections are the representations of the globe on a flat surface. There are many types of map projections but I'll teach you about the four most important ones.
The most common map projection is the cylindrical projection. Here, the areas close to the equator have a little distortion and the closer you move to the poles, the more distorted and less accurate the map becomes. An example of this is Greenland. On the map Greenland appears to be bigger than it really is on the globe because of the cylindrical projection.
Then we have the plane projection. This projection is created by placing an imaginary screen directly above/below of the globe. This map projection is not very common though. Another map projection is the conic projection. This is created by placing a cone shaped screen on a globe. This is more accurate than a cylindrical but the further down in the map, the more distorted and less accurate it becomes.
Wow! That is so awesome!
And the last map projection I'll tell you about is the interrupted projection. There are many different types and these maps try to depict the continents as accurate as possible and leaves blank spaces in the areas that are less important.
I'm glad I got the chance to help you Sarah!
Thank you so much Pat for helping me learn about map projections, you're the best!
