[postgis-users] ST_Slope

[JamesH]

"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...

Regards,
James
