I'm trying to merge about 345 tifs NED 10M data for the continental U.S. I processed the data from ArcInfo Grid to tif (see bottom for the output of one of the tifs from gdalinfo) using gdal_translate. The error below is generated from the attempted merge, how I do build GDAL with BigTiff support? Also I noticed my windows version of the tool supports the --optfile parameter, but not the linux python script version. Can this command handle all 345 files on one command? Are there other best practices methods that I should be aware of, I prefer to process on the linux system since they, but am open to processing on windows. Whatever works.<br>
