I try to reproject a coverage class using arcpy.Project_arc. The synthax states
arcpy.Project_arc(in_cover, out_cover, projection_file)
but I cannot really get the last argument - that is, the projection file - to work. The esri webpage describing the function (Project—Help | ArcGIS for Desktop ) inputs some kind of transformation file using a prj file extension but its not the usual proj-file that is used with shapefiles. When trying to create a custom transformation using the appropriate toolbox I instead get a file with the gtf extension.
Can anyone please point me in the right direction on whats going on...???
