Hi list,
I have a table with all sort of geometry errors - self-intersections, holes
outside polygon, etc. I have some recipes to tackle these problems, but I
have a doubt - is there an order or precedence by which I should tackle
them? I ask these because I have more than one kind of error in a s
Hello,
You might want to try this projection:

This the most accurate projections, despite the description on the spatial
reference site. I am doing related work and found this calculator at the
following url

Hello,
I am attempting to store some gps coordinates that i collected for a geospatial
db in precision ag. I created a table with a geometry column called
"Coordinates" using the command "Coordinates" geometry(Point,4326). I then
populated the column using the command
ST_SetSRID(ST_MakePoin
Evan, the internal geometry storage format cannot be changed.
You can query your database to get the "human" values with ST_AsText and
other functions for printing. This depends a lot on what you need to do.

Google the function st_astext . Should do what you want. Alternatively you
can use st_x and st_y.

There are many geometry output functions [1], such as
ST_AsLatLonText() [2], e.g.:
44°7'15.636"N 89°32'8.880"W

I tried tesselating a cube
NOTE:
SELECT ST_Dimension(ST_GeomFromText('POLYHEDRALSURFACE Z( ((0 0 0, 0 0 1, 0
