EPSG 4326 vs EPSG 3857 (projections, datums, coordinate systems, and more!) Mercator vs. well…not Mercator (Platte Carre)
Application: Apply these concepts to visually compare the same data under multiple projections and critically analyze the effects of different projections. This exercise will teach you about different geographic coordinate systems and projections hands-on by using "on-the fly" projection to visually comp...

This module begins with concepts that define the geographical referencing standards of the Earth. Topics include latitude and longitude, projections, coordinate systems, and datums. 9.1 Geographic Coordinate System Latitude and Longitude Any feature can be referenced by itslatitudeandlongitude, which arean...
To map the world more accurately, GIS uses a variety of geographic coordinate systems and projections. The basic idea behind geographic coordinates is to convert a 3D sphere or spheroid into a flat map. While we know the earth is not flat, it's also not round. It's actually an ellipsoid...
