Hi, And thanks for the swift response! My GDAL version is: GDAL 1.11.0, released 2014/04/16.
I recompiled GDAL recently (but not PostGIS). Can that be the source of error? However, ASCII and Tiffs with assigned NoData work… Cheers Stefan From: Rémi Cura [mailto:[email protected]] Sent: 16. mai 2014 11:24 To: Blumentrath, Stefan Cc: GRASS developers list ([email protected]); [email protected] Subject: Re: [GRASS-dev] GRASS created geotiff do not properly load into PostGIS (raster2pgsql) Hey, what is your version of gdal (type `gdalinfo --version`) Cheers, Rémi-C 2014-05-16 11:14 GMT+02:00 Blumentrath, Stefan <[email protected]<mailto:[email protected]>>: Hi, And sorry for posting on two lists. Just don`t know where the issue belongs to… I tried to load a set of raster maps in Geotiff format, which I created in GRASS using r.external.out, into PostGIS 2.1.2dev. In PostGIS the raster datasets only contain NoData values, while gdalinfo –stats produces reasonable statistics for the respective GeoTiffs. I did some trouble shooting and found that the problem was that GRASS did not assign a numerical NoData value to the GeoTiff, but “nan”. When I gdal_translate same GeoTiff with –a_nodata -9999, raster2pgsql loads the resulting file just fine. Is raster2pgsql supposed to read rasters with nan as NoData values (using –N -9999 in raster2pgsql had no effect btw.) or should GRASS (r.external.out) assign a NoData value to the produced raster datasets?
