gdalinfo does not give the right corner coordinates.
what changes do I have to make for gdal to ingest?
(I can use gdal_translate, but try to avoid that route)
Shawn,
The PCI .aux file is only intended to be used with "north up"
images. I see your corner coordinates are not regular. For instance
the longitude of the upper left and lower left corner are not the same.
You could wrap the same dataset in a "raw" VRT and associate GCPs
with it to identify the corner coordinates instead of trying to set
a geotransform. Scan down to the raw file part of:
