A few days ago I posted a message regarding composing satellite images Geotiff in one final image. All inputs were 1 band images created with same options. I posted the info obtained using gdalinfo and Image Magick for one of the input images.
<br>When running gdal-merge.py without -pct option, I obtain a grey scale output image. Not the desired result.<br>When running gdal-merge with the "-pct" then, I obtain a full black image.<br>Frank requested me to send one of the input images, but this Email never made it to the list due to the size of the file.
<br>A gzip, tar version of one of the input images can be downloaded from: <a href="http://www.mediamax.com/izzybitsie/Hosted/AS_GMSNO_00_20061122205548.tif.gz">http://www.mediamax.com/izzybitsie/Hosted/AS_GMSNO_00_20061122205548.tif.gz
</a>.<br><br>Could anyone give me a hint on what is wrong with these images that gdal-merge.py cannot compose?<br><br>Thanks<br><br><br>
