gdalbuildvrt and gdal_translate unable to handle large INT32 nodata values

Reported by: pauldzy Owned by: warmerdam
Priority: normal Milestone: 1.11.4
Component: GDAL_Raster Version: 1.11.2
Severity: normal Keywords: gdalbuildvrt gdal_translate mosaic nodata


I have INT32 single band rasters created by US EPA where the nodata values are set to -2147483647.

When these rasters are run through gdalbuildvrt the VRTRasterBand is set as "-2.14748364700000E+009" and the individual rasters are set as "-2.14748e+009". When gdal_translate operates upon the vrt to mosaic the two rasters, the nodata values are not respected. Manually changing the vrt values to be the full "-2147483647" makes no difference.

Does this suggests that nodata values cannot be larger than a float32 with gdal? I see previous bug reports which suggest this type of thing but nothing definitive. Perhaps this is a documentation issue?

Thanks, Paul
