Re: [gdal-dev] What's the best way to fix an incorrect projection in a geotiff

[David Strip]

thanks. Somehow I missed the "override" implications of -a when I looked at gdal_translate. And yes, I believe the coordinates are OK in my file, just a bad SRS.

State-Plane, but the coordinate system is listed as GCS WGS84. What's the best way to fix this, esp if I have multiple files with this problem? I can use listgeo to get a file of the all the tags, edit the coordinate system to the correct value, then use tiffcp on each file to strip out the tags and then use geotifcp to put back the correct ones, but I suspect there's a better way, perhaps using gdalwarp with the -to option set to override the input SRS, creating a trivial warp? Or maybe something simpler that I'm not seeing. thanks David _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev -- ---------------------------------------+-------------------------------------- I set the clouds in motion - turn up   | Frank Warmerdam, warmer...@pobox.com light and sound - activate the windows | http://pobox.com/~warmerdam and watch the world go round - Rush    | Geospatial Software Developer
