Projections in GIS are commonly referred to by their "EPSG" codes, identifiers
managed by the European Petroleum Survey Group. One common identifier is
"EPSG:4326", which describes maps where latitude and longitude are treated as
-X/Y values. Spherical Mercator has an official designation of EPSG:3785.

However, before this was established, a large amount of software used the
