Basics of Map Projection
Following up from my recent educational video on geodesy, we need to understand a map is a 2D representation of a 3D surface. Map projections converts the world into a small sphere and later flattened on plane surface. In that process, distortions happens (Wondering why Greenland is bigger than Africa?- Because of the map projection!). Important fact: There is no such thing as WRONG PROJECTION. It is either good or poor choice of map projection for the map use. Learn more in the video.
