[gdal-dev] gdal_translate JPEG to GeoTiff (help! no one answered...)

[Chaitanya kumar CH]

Marco,

You mentioned that you cropped the original image. I guess you left
the meta-data containing the projection info intact. See if you get
the correct locations on the map with the original uncropped image.
Better yet, check the original image using the '-projwin' option in
gdal_translate.
