Partial solution could be to use gdalbuildvrt http://www.gdal.org/gdalbuildvrt.html Running gdalbuildvrt alltiles.vrt *.tif will create a vrt file with one common colortable and all tif files as separate SimpleSources. Changing them into ComplexSources and adding LUT blocks should be doable with a clever test editor. However, after running gdalbuildvrt you will have one dataset instead of bunch of tiles and if you want tiles back you will need to split the "alltiles.vrt" file somehow. If you do not need tiles you can avoid this and convert the whole vrt file into one single geotiff. -Jukka Rahkonen- _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
