We currently have an ArcMap addin that will convert selected or all point features to a SEGP1 file. We also allow projections to a different Coordinate System and this is where it gets tedious. We want to list out all valid coordinate system from arcgis. Currently, we have an xml file where we store the Coordinate System list.
Is there any way where we can retrieve the list of coordinate systems using ArcObjects?
We are using ArcObjects 10.1 .NET btw.
