HEG tool seems to be reading in my HDF ASTER file as lat long geographyic projection and writes them that way, theoption to change the projection to UTM are permanently greyed out. Why is that. I though ASTER was UTM projected.

Good tool igf you are only occasionally working with HDF files and just want to export the data to another environment that does not provide hdf support.
