FIELD DEFINITION AND SCOPE
Information about the coordinate system developed on a planar surface. The information
is provided to allow the user of a geospatial data set to identify the quantities of
distances, or distances and angles. These define the position of a point on a reference
plane onto which the surface of the Earth has been projected.
