Class: AbstractCrs

AbstractCrs

Creates an coordinate reference system for a globe and data. A coordinate reference system is a coordinate system that is related to an object by a geodetic datum. A coordinate system is a set of mathematical rules for specifying how coordinates are to be assigned to points
