That is a surprise.
In all my tests I had no memory problems with gdal_retile. Sometimes I had
some memory problems with gdal_merge. The biggest input file for gdal_retile
was a 80 GB Erdas image (not compressed) and it works fine.
I have never testet with an ECW File and my tests run on a Li
gdal_retile.py definitely creates georeferenced tiles, I developed this
utility.
I did some experiments reprojecting the single tiles while retiling, but it
simply does not work. As a consequence I canceled the reprojecting support.
The solution for your problem is:
1) Use gdal_merge to cr
