[gdal-dev] gdal2tiles.py and ProjNatOriginLongGeoKey

[Zachary Fisk]

 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.


*Sample command parameters I'm passing to gdal_merge.py*
gdal_merge.py -o big2.tif -of GTIFF -co BIGTIFF=YES -co TILE=YES -co
COMPRESS=DEFLATE -co PREDICTOR=2 -co BLOCKXSIZE=128 -co BLOCKYSIZE=128
demgrid_101_1.tif demgrid_101_2.tif demgrid_101_3.tif demgrid_102_1.tif
demgrid_102_2.tif demgrid_102_3.tif demgrid_103_1.tif demgrid_103_2.tif
demgrid_103_3.tif demgrid_104_1.tif
Warning 6: BIGTIFF requested, but GDAL built without BigTIFF
enabled libtiff, request ignored.
Segmentation fault
