Hello, I was doing some point rasterization of vector data from postgis database by using gdal_rasterize from a bash script, the command looks like this:
gdal_rasterize -a value -b $COUNT -tr $RESOLUTION -te $BBOX -a_nodata $NODATA -a_srs $EPSG PG:'host=localhost dbname=databio user=postgres password=postgres' -sql "SELECT ST_Centroid(g.geom), AVG($COLUMN) as value FROM $GRID g, $OBSERVACION o WHERE utc_date='$DATE' AND vessel_cfr='$VESSEL' AND ST_Intersects(o.geom,g.geom) IS TRUE GROUP BY g.gid" ./bands/$DATE2"_"$COLUMN".tif" The problem is that I want to generate a geotif file with multiple bands, so if I remove the -b $COUNT parameter and value it works and I get a .tif file with the -a value printed on it for band1, but the idea is to reuse that command in a for loop to add further bands and I am gettin this error: -b option cannot be used when creating a GDAL dataset. I tried to run the comand once to create the tif file without the -b option and then run it additional times with the -b option when the tif is already created but it makes no difference. I am stucked with this and I am starting to think that -b option can only be used with -burn parmeter and as far as I know -burn is only for constant values... thank you in advance for any help. cheers, Mario This e-mail and the documents attached are confidential and intended solely for the addressee; it may also be privileged.
