I am using SDE as my raster data source with the ultimate goal to tile this dataset: I am running the following gdal_translate command to generate the initial VRT:
gdal_translate -projwin 390605 5588320 410128 5568805 -a_srs EPSG:25832 -a_nodata none -of vrt SDE:server,5153,db,user,pw,table,image clippedvrt.vrt
Tiling the resultant VRT produces tiff with weird colors. The colors are either intensified or totally different from the original as you can see from the test results
Here is the result of gdalinfo on the resultant VRT:
Band 1 Block=128x128 Type=Byte, ColorInterp=Palette

could someone shade some light as to what might be happening.
Thank you
