[gdal-dev] gdal_merge.py on large Tiff's. gdalwarp not working properly.

[Chaitanya kumar CH]

Aaron,

This could be solved by using the nodata attribute. You can set the nodata
value in the source in the vrt file[1]. The vrt driver will ignore the
nodata areas.
If you have problem with that, rerun the gdalwarp operation and make sure
you get the nodata values.
Use the -srcnodata and -dstnodata options in gdalwarp.
