I have a couple of large sets of imagery I need to mosaic using GDAL. The sets are currently in tiff format with 18 tiles totaling about 20gb in size. I have attempted to mosaic using both the gdal_merge.py and gdalwarp utilities. The results are either a completely black raster or only white pixels where the image should be. Does anyone know how to prevent this from happening? Looking over the documentation I did not see any parameters that I thought would make a difference, but am I missing one?
I also attempted the same process with the same images in PNG format, and got the same results.
