Hi !
i had to merge several images to one large an have even problems with
the color. (the data of my two test-image you found at the end of this
posting)
if i merge this two images via qgis-gdal > merge i get two different,
but unuseable, images
look at the following images:
with pseudocolortable for the first image -
http://www.tappenbeck.net/forum/gdal/gdal_qgis_with_colortable.jpg
without pseudocolortable for the first image -
http://www.tappenbeck.net/forum/gdal/gdal_qgis_without_colortable.jpg
other problem can anyone tell me the right way ?
when i try to start the command via msys like:
gdal_merge.bat -pct -of GTiff -o
E:/jan_testauswertungen/xxxx_test/Luftbild/dialog_mit.tif
E:/jan_testauswertungen/xxxx_test/Luftbild/675730.tif
E:/jan_testauswertungen/xxxx_test/Luftbild/675735.tif
i get the message in qgis 1.7.4 - windows7:
/c/QuantumGISWroclaw/bin/gdal_merge.bat: line 1: @python: command not found
did i use the alternative command gdalwarp like
gdalwarp E:/jan_testauswertungen/xxxx_test/Luftbild/675730.tif
E:/jan_testauswertungen/xxxx_test/Luftbild/675735.tif
E:/jan_testauswertungen/xxxx_test/Luftbild/gdalwarp.tif
i get the same result like
