Supported coordinate system units

The database uses a specific coordinate systems syntax and supported coordinate system values to provide a standard textual representation for coordinate system information.

The default units for the supported coordinate for Geospatial Analytics, GCS_WGS_1984, is as follows:

Supported linear unit
