Description
ExportESRISpatialReferenceToPRJFile converts an ArcGIS style spatial reference into the well-known text string. Here is an example (reformatted):
GEOGCS["GCS_North_American_1983",
DATUM["D_North_American_1983",
SPHEROID["GRS_1980",6378137,298.257222101]],
PRIMEM["Greenwich",0],
UNIT["Degree",0.0174532925199433]]
Remarks
To convert a spatialreference into an ArcInfo workstation format (for TINs, GRIDs, or coverages), use IPRJSpatialReferenceGEN_ExportSpatialReferenceToPRJ.
