Map Projections – The Good, The Bad and The Distorted

I recently found 2 interesting videos on the basics of Map Projections.

Hopefully this sheds some light on why we use “Map Projections” with Trimble GPS Pathfinder Office and Trimble Positions Desktop Add-in for ArcGIS.

Why all the world maps are wrong

Map Projections of the Earth

These two videos just cover the basics of “Map Projections”.  You will see more videos on this topic at the end of both videos.

I will post future videos about Coordinate Systems, Datums and Geoids.
