gdal_contour fails with 4gig+ file

[treaves]

I am attempting to import contour information into a PostGIS-enabled database. I am trying to follow the information on this site: ​http://wiki.openstreetmap.org/wiki/Contours#Importing_the_SRTM3_data_.28deprecated.29 and am using the script. The page states that srtm_generate_hdr.sh is no longer needed, but, I can find no instructions that do not use this script.

I am importing data from ds.cr.usgs.gov/srtm/version2_1/SRTM1/Region_01 . The first couple of files in that directory import. When the file N38W114.hgt.zip is processed, however, one of the intermediate files created by shp2pgsql starts growing in size, and when it reaches just over four gig, the max file size, it fails. This particular data file isn't the largest that is imported.

So I'm not sure how to troubleshoot were exactly the issue is; I suppose the issue could be with the data file, but, as several other files imported fine, I think the issue may be with shp2pgsql.

It's the shp file that grows & fails. Also, the app does not notice this failure, and continues to try & process the input.

RROR 1: Failed to write shape object. File size cannot reach 4294967228 + 808. ERROR 1: Failed to write shape object. File size cannot reach 4294967228 + 808.

These are the actual error messages.

Sorry, this is gdal_contour, not shp2pgsql.

gdal_contour and that error are directly from GDAL, not PostGIS. You should ask the GDAL mailing list.
