I'm not aware of a standard for that. > Do you happen to know where PostGIS Raster is documented?

This is documented there : http://trac.osgeo.org/postgis/wiki/WKTRaster/Documentation01 > > Thank you in advance for your help, > > Daniel > -- Spatialys - Geospatial professional services http://www.spatialys.com _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
