Hello Marius, Actually am not sure as my colleague did the actual test. But we tried visualization also in QGIS and had the same result as ArcMap. I will check this again and let you know. In the mean time, we decided to follow Andre´ s approach to strip the VRT off the wrong palette and then apply the right palette.
Thanks and regards, Moses From: gdal-dev-boun...@lists.osgeo.org [mailto:gdal-dev-boun...@lists.osgeo.org] On Behalf Of Marius Jigmond Sent: 09 November 2013 03:43 To: Andre Joost; gdal-dev@lists.osgeo.org Subject: Re: [gdal-dev] gdal_translate produces tif with different colors as original I noticed you're using ArcMap for visualizing the results. Did you check what histogram/gamma stretch gets applied by default when you load the layer? I run into this issue often as results from GDAL operations appear much worse when loaded into ArcMap compared to originals. When I turn off stretching, both histogram/gamma, results are nearly identical to original. -marius > To: gdal-dev@lists.osgeo.org<mailto:gdal-dev@lists.osgeo.org> > From: andre+jo...@nurfuerspam.de<mailto:andre+jo...@nurfuerspam.de> > Date: Thu, 7 Nov 2013 16:54:32 +0100 > Subject: Re: [gdal-dev] gdal_translate produces tif with different colors as > original > > Am 06.11.2013 21:32, schrieb Jukka Rahkonen: > > > You're advised to preprocess your rasters with other > > tools, such as pct2rgb.py or gdal_translate -expand RGB to operate > > gdalbuildvrt on RGB rasters instead." > > > > I proposed that, but have a look at the color palette of the VRT: > > <http://gis.stackexchange.com/questions/76662/gdal-translate-produces-tif-with-different-colors-as-original> > > Is it a fault of the source or the driver? > > Greetings, > André Joost > > _______________________________________________ > gdal-dev mailing list > gdal-dev@lists.osgeo.org<mailto:gdal-dev@lists.osgeo.org> > http://lists.osgeo.org/mailman/listinfo/gdal-dev
