Hi, I need to make a mosaic with gdalwarp using a lot of large files (ASTER GDEM, Europe coverage). For this, I need the bigtiff support, but I'm not sure it is working properly. Here is my work flow:
# RES=0:00:01 RES=0.000278 BIGTIFF="-co BIGTIFF=YES" # GDAL cache in megabytes CACHE="--config GDAL_CACHEMAX 8000 -wm 8000" LIST="" for i in `cat /home/leomarg/Desktop/aster/elenco_aster_europa_riga`;do LIST="$LIST $i"; done gdalwarp $CACHE $BIGTIFF -srcnodata -9999 -dstnodata -9999 -r bilinear -tr $RES $RES $LIST mosaik_$RES.tif I get the following error: [...] ERROR 1: Integer overflow : nDstXSize=49460, nDstYSize=70144 Processing input file ASTGTM_N55E011_dem_lzw.tif. ERROR 1: Integer overflow : nDstXSize=49460, nDstYSize=70144 Processing input file ASTGTM_N55E012_dem_lzw.tif. ERROR 1: Integer overflow : nDstXSize=49460, nDstYSize=70144 More than 1000 errors or warnings have been reported. No more will be reported from now. [...] So, it looks like the bigtiff support is not working properly. I'm on Red Hat 64 bit and compiled gdal 1.9.1 from source, with the following configure: ./configure --with-libtiff=internal -with-geotiff=internal What am I missing? And, how can I check if the bigtiff support is active in my gdal installation? TIA, -- Dr. Margherita Di Leo
