Is OGRCreateCoordinateTransformation() part of the usual GDAL/OGR library? I know that OGR is a "loosely coupled subcomponent" of GDAL, so perhaps it omitted? I am linking against gdal_i.lib and it is coming up undefined. It looks like it is the only way to convert coordinates, a very important ability, so i would hope that it is built in to GDAL somehow. -Ben
