The order of union and clip seems illogical. First union, then clip (once).
This may not be a big difference for a small parcel (2048 seems to be smaller
than a 100 x 100 tile), but should be for others (multi-tile parcel coverages).

Hi list,
i have a polygon table named "common.parcel" (3432 records).
and a 11038x13438 pixels raster table "resource.zones" (100x100 tiled)
with the following values:
0: wetland;
1: strong slope;
2: workable surface.
As a "zonal histogram", i'd like to get this kind of result:
parcel_gid | 0

Thanks!
We are currently considering using PostGIS Topology only to maintain a
topology aware copy of the data (to be used for analyses where topology
matters) and use the original geometry (containing circular strings)
when we have to (re)generate output geometry.

Hi all,
I have on my mac (Mavericks OS) Mapserver 6.2.1 and PostGIS 2.1.2 installed
via homebrew and my version of GDAL is 1.10.1_1. Apparently everything
works fine ...
When I try to display a raster layer from PostGIS, got the following message
:
msDrawMap(): Image handling error. Failed to dr
