<span class="gmail_quote"></span>Hi,<br>I am trying to compose a geotiff satellite image by stitching several satellite geotiff images.<br>All of them are one band images with same pseudo color table. <br>When merging the images with -pct to preserve the color table, I get a black image. When I don't use this option, I get a fainted final picture since the color is now Grey Scale.
<br><br>I noticed that the pseudo color table for each of the input images look different if I use gdalinfo and ImageMagick command identify. <br>I attached the gdalinfo and IM info files for one of the input images:AS_GMSNO_gdalinfo.dat and AS_GMSNO_IMinfo.dat and the gdalinfo of the output image obtained using gdal_merge.py with and without "-pct" option(out-pct_gdalinfo.dat and out_gdalinfo.dat).
<br><br>Command used to obtain output image: gdal_merge.py [-pct] -o out.tif -v in1.tif in2.tif in3.tif in4.tif in5.tif<br>You can see one of the input images in:

I am running out of time to solve this issue.
