Selon Chris Emberson <chrisember...@hotmail.com>: The behaviour you see is expected. -expand rgb only works for bands that have color maps. You can transform your grey scale FILEA.asc into a RGB file by doing this :
gdal_translate -of GTiff -co "TILES=YES" -b 1 -b 1 -b 1 FILEA.asc FILEB.tif This will use the source band 1 for the R, G, B components of the output file. You may need to use the scaling/translate options of gdal_translate to reduce the dynamics to 8 bits. > > I am having trouble converting a single band raster (.asc) when using the > GDAL utility gdal_translate (version 1.6) > > This is the command... > gdal_translate -of GTiff -co "TILES=YES" -expand rgb FILEA.asc FILEB.tif > > I get this message.... > > > > > Error : band 1 has no color table > > I want to be able to tile this raster using Mapnik - therefore it needs to be > a 3 band tiff - Can anyone help with this problem? > > Thanks in advance > > Chris > > > > > > > > _________________________________________________________________ > Save time by using Hotmail to access your other email accounts. > http://clk.atdmt.com/UKM/go/167688463/direct/01/ _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
