[postgis-users] giving rank values to raster is possible

[Ahmet Temiz]

Hi,

Rather than categorizing raster in *% form, giving rank

values is possible ?, like [value1-value2] 200 0 0

"SELECT ST_ColorMap(the_raster,'100% 255 0 0",

            "    75% 200 0 0",  >>>> ?? * 0-10 200 0 0
            "    50% 100 0 0",
            "    25% 50 0 0",
            "    10% 10 0 0",
            "nv 0 0 0', 'NEAREST') the_raster",

regards
