"now that you got ST_Slope working you have to pass it your own raster...."
Sorry Pierre, how do you mean my own raster? Does SELECT ST_AsBinary((gv).geom), (gv).val FROM (SELECT ST_DumpAsPolygons(ST_Slope(rast) gv FROM height_newcastle) foo calculate the slope surface from height_newcastle and then display it in OpenJump? Do I not need to use '([rast.x] - 1) * 10 + [rast.y]') to assign the unique values anymore? Apologies to drag this thread on...
