Hi folks,
I'm working with someone trying to merge and reproject 1108 4 band tiff
images into 1 BIGTIFF image. The command line options are as follows:
gdalwarp -s_srs EPSG:26918 -t_srs EPSG:32119 -wo 'SOURCE_EXTRA=3' -wo
'SKIP_NOSOURCE=YES' -wm 4000 --config 'GDAL_CACHEMAX=2000' -tps -rcs
-srcnodata '0' -of GTIFF -co 'BIGTIFF=YES' -co 'TFW=YES' -tr 1 1
/work/lisa/utm18/*.tif
/work/lisa/reprojected_and_merged/naip_utm18_32119.tif
The process stops with the following error:
ERROR 1: Integer overflow : nDstXSize=29400, nDstYSize=19377
The command worked fine with 33 tiff images. The individual is using gdal
1.7.2 on 64 bit linux.
Googling a bit and grepping the source code makes me think the problem is
in reading the a tiff file, perhaps a badly formatted input tiff image?
I suggested that the user try smaller chunks based on latitude rather than
the whole utem zone for the state.
Thoughts?
