Introducing Coordinate Systems and Map Projections

Why should you care about coordinate systems and map projections? The coordinate system is a fundamental part of GIS data. Without the coordinate system, you cannot overlay or analyze two datasets properly. A map projection is an integral part of a projected coordinate system which strongly affects your analyses and the look of your data. Learn about different coordinate systems; figure out an unknown coordinate system, and check out various map projections. -------------------------------------------------------------------------------------------------------------------------- Follow us on Social Media!
