Hello, I'm trying to calculate how much a polygon points in a given
direction.
This is to calculate how much light would come from a given light source.
This means that for each segment of its outer ring I want to calculate the
scalar (dot) product of
outward normal vector (whose magnitude is
Hi,
I want to create a polygon from the given points and clip the area's within
the polygon.
I just tried with the below one to create a polygon,
\d test_polygon;
Table public.test_polygon

Your table is setup to accept only MULTIPOLYGONs. Either adjust your table
constraint to allow regular polygons or convert your polygon to a
MULTIPOLYGON.

Why drop the feature ?
If we want a true repository revision we should provide
that in an header file (which we'd touch) and use that when
we see fit. I wouldn't drop the file-specific one though,

So after some googling I see similar problems, but no solutions posted.
I am trying to union a buffer, but the query is returning no results. Here is
ultimately what I would like to achieve:
select st_union(st_buffer(the_geom,0.1)) as the_geom from
base.current_assessment_parcel
Here are
Forgot to mention, I have tried this on a couple other polygon and polyline
tables with similar results.

Not sure what you are asking, but I'll take a stab in the dark.
When you retrieve geometry as SVG what you get back is the contents of a
path attribute node.
So if an SVG path element is written path d=X/ the result of the query
is X, or the value of the 'd' (data) attribute, not an XML element,

Rick - thanks for answering.
I am in the process of learning a little XML.
I understood that a query such as 'Select AsSvg(the_geom) from p_id.image' went
to Postgis and the return (the geometry) comes back.
I think you are saying that this is also in the xml path and xml interprets
this
