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.
Happy Learning!

  1. Good to see Danesh. I often see people tying themselves in knots with projections and it's often overlooked by GIS users. Great introduction though.

  2. Map Projections is a difficult topic.for me. The basics is easy. However, moving one coordinate system to another is difficult to grasp. That is why people get into knots because of this.
