Hello, I'm willing to create a PL/pgSQL function in orden to obtain normalized (0-1) rasters. This is what I have so far:
The thing is that I don't know how to handle the variables inside the ST_MapAlgebraExpr expression. As it is now, I get an error when running the function because it takes the minVal and maxVal variables as if they where columns of some table. Is there a way to use inside the expression those variables I defined previously? Thanks a lot! -- View this message in context: http://postgis.17.n6.nabble.com/Problem-using-ST-MapAlgebraExpr-tp4514561p4514561.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
