<br><font size=2 face="sans-serif">Hi folks,</font>
<br>
<br><font size=2 face="sans-serif">I'm working with someone trying to merge
and reproject </font><tt><font size=2>1108 4 band tiff images into 1 BIGTIFF
image. The command line options are as follows:</font></tt>
<br>
<br><tt><font size=2> gdalwarp -s_srs EPSG:26918 -t_srs EPSG:32119
-wo 'SOURCE_EXTRA=3' -wo<br>
'SKIP_NOSOURCE=YES' -wm 4000 --config 'GDAL_CACHEMAX=2000' -tps -rcs<br>
-srcnodata '0' -of GTIFF -co 'BIGTIFF=YES' -co 'TFW=YES' -tr 1 1<br>
/work/lisa/utm18/*.tif<br>
/work/lisa/reprojected_and_merged/naip_utm18_32119.tif</font></tt>
<br>
<br>
<br><font size=2 face="sans-serif">The process stops with the following
error:</font>
<br>
<br><tt><font size=2>ERROR 1: Integer overflow : nDstXSize=29400, nDstYSize=19377</font></tt>
<br>
<br>
<br><font size=2 face="sans-serif">The command worked fine with 33 tiff
images. The individual is using gdal 1.7.2 on 64 bit linux.</font>
<br>
<br><font size=2 face="sans-serif">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?</font>
<br>
<br><font size=2 face="sans-serif">I suggested that the user try smaller
chunks based on latitude rather than the whole utem zone for the state.
</font>
<br>
<br><font size=2 face="sans-serif">Thoughts?</font>
