Yes. PostGIS raster uses GDAL for the loader (for the numerous source raster formats), warping API, one of the two possible polygonization methods (ST_DumpAsPolygons) and the rasterization function.
The main reason for GDAL 1.9 is correct output of pixel values from ST_DumpAsPolygons which consumes GDAL's polygonization methods. -bborie On 09/04/2012 11:23 AM, Brian Fitzgerald wrote: > Are you saying that Postgis should be using GDAL 1.9? > > Thx! > > - Brian > > > > > On Tue, Sep 4, 2012 at 2:08 PM, Bborie Park <bkp...@ucdavis.edu> wrote: > >> Issues with QGIS accessing PostGIS raster typically arises from the GDAL >> version used by QGIS.
