hi !

i had 11 strip-images of aerophotos with total 200MB.

i want to merge this with gdal_merge.py by using FWTools in Windows.

gdal_merge -v -o file.tif -of GTIFF --co --optfile filelist.txt

the result is a file with 8.85 GB. when i open the file in OpenEV one of
the image-strip will not show ! it is black.

look at http://www.tappenbeck.net/forum/gdal/gdal_merge_missing_strip.jpg - there is a picture of this result in OpenEV.

then i try to make a workaround and translate every ecw to tif - open eveny one to controll -> ok.

in the next step i merge these 11 strips to one tif-file with gdal_merge

but the result - one strip is missing !

can anybody help me ??

regards Jan .-)
