Hi, all this is my first post to this list. I am fiddling with some gps data that I want to plot onto a .BSB chart.
I think I have understood howto project the gps data to geo-coordinates with the spatialreference and transformpoints. And then it seems possible to translate from screen to geo-coordinates with GCPToGeoTransform. But how to do the inverse geo-coordinate to screen with GCP. It seems that the GDALCreateGCPTransformer and GDALGCPTransform can do both. But I cannot find the support in C# or is it hidden in some class? Regards Patrik Svensson
