I have a problem with applying a custom geographic transformation on shape files.
I have shape files from Vietnam that are in a VN200 projection. I was using the "create custum geographical transformation" to build a transformation file. This is working fine, however, I need first to definde the projection of the files as the ArcGIS internal VN-2000 projection.
My problem now is that I can apply this transformation only on raster data, but not on shape files. This is a main problem for me, as I need to convert lots of shape files.
