<p class="MsoNormal"><span lang="EN-US">Hi,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">And sorry for posting on two lists. Just don`t know where the issue belongs to…<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><br>
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.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">In PostGIS the raster datasets only contain NoData values, while gdalinfo –stats produces reasonable statistics for the respective GeoTiffs.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">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”.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">When I gdal_translate same GeoTiff with –a_nodata -9999, raster2pgsql loads the resulting file just fine.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">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?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Many thanks in advance,<o:p></o:p></span></p>
