The only idea I have is pretty obvious and I guess you'd already have it, you probably require more memory than available. The --config GDAL_CACHEMAX 500 -wm 500 options require at least 1 GB. Otherwise it's a more subtle bug. Unfortunately it's not very practical to try to reproduce it as your input datasets are pretty big to download.
I've downloaded the first two files and observed that they are at the same resolution and projection so you could probably use gdal_merge.py instead _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
