Question

What is a map projection? What problem is caused by map projections?

Answer 1

A map projection is the way a given cartographer has taken the Earth, which is a three-dimensional globe, and projected it, that is, shown it on a flat surface. Because maps are shown in two dimensions (height and width but no depth), distortion occurs. When we take the Earth and try to flatten it onto a map, we aren't going to be able to display it completely accurately. Projections will always distort areas, shapes, or distances.

Answer 2

1)In cartography, a map projection is a way to flatten a globe's surface into a plane in order to make a map. This requires a systematic transformation of the latitudes and longitudes of locations from the surface of the globe into locations on a plane.2)Maps cannot be created without map projections. Allmap projections necessarily distort the surface in some fashion.
