Exports a spatial reference to a PRJ file.
[Visual Basic .NET] Public Sub ExportESRISpatialReferenceToPRJFile ( _ ByVal prjFile As String, _ ByVal SpatialReference As ISpatialReference _ )
[C#] public void ExportESRISpatialReferenceToPRJFile ( string prjFile, ISpatialReference SpatialReference );
[C++]
HRESULT ExportESRISpatialReferenceToPRJFile(
BSTR prjFile,
ISpatialReference* SpatialReference
);
[C++] Parameters prjFile
prjFile is a parameter of type BSTR SpatialReference
SpatialReference is a parameter of type ISpatialReference*
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]]
To convert a spatialreference into an ArcGIS for Desktop Advanced workstation format (for TINs, GRIDs, or coverages), use IPRJSpatialReferenceGEN_ExportSpatialReferenceToPRJ.
