I seem to be missing some key point in understanding the use of OGR Projections.
The OGR Projections Tutorial (www.gdal.org/osr_tutorial.html<http://www.gdal.org/osr_tutorial.html>) very clearly describes how to set up a new OGRSpatialReference, but does not tell how to determine and query the OGRSpatialReference from an existing image data set (e.g. and GeoTiff image). Could someone please point me to examples/instructions on how to do this? Thanks. Jim Tilton ________________________________ Dr. James C.
