Hi again, when developing other functions I encountered a new problem with the 2 raster band version of ST_MapAlgebraExpr(). First of all, this is the function (it calculates the ordered weighted average out of two rasters):
Then, I try to execute it like this: but I get this error: Invalid pixel type? I'm using the same maps than before and the structure of the function is quite similar... but I didn't get this error with the normalize function nor others. -- View this message in context: http://postgis.17.n6.nabble.com/Problem-using-ST-MapAlgebraExpr-II-tp4514561p4531261.html Sent from the PostGIS - User mailing list archive at Nabble.com. _______________________________________________ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users
