I need to do an ordered weighted averaging with the input rasters: assuming they all have the same extension and characteristics (like pixel size), for position (1,1) I take the value of every raster, the I sort those values to assign the weights and finally I compute the average to store it in the (1,1) position of the output raster. And so on with the rest of the positions.
As you can see, I need to extract every pixel of every raster. -- View this message in context: http://postgis.17.n6.nabble.com/Extracting-cell-values-into-a-matrix-tp4998636p4998700.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
