Sure is, check out the ST_Buffer function
http://postgis.refractions.net/docs/ST_Buffer.html
ST_Buffer(geometry g1, float radius_of_buffer);
If you give it a point as g1, and the radius of the circle it will
calculate a pseduo-circular polygon for you. If you have two points
g1 and g2 you coul
I found this really neat Google Maps example where you can draw polygons
using 2 points: the center and one vertex.
See http://www.barnabu.co.uk/geapi/polyplot/
Is there a POST GIS function to create the corresponding polygon?

Removing the EPSG lookup from the equation changes nothing:
echo "59 21" | proj +proj=tmerc +lat_0=0 +lon_0=15.808278 +k=1
+x_0=150 +y_0=0 +ellps=bessel +units=m +no_defs | invproj
+proj=tmerc +lat_0=0 +lon_0=15.808278 +k=1 +x_0=150 +y_0=0
+ellps=bessel +units=m +no_defs

Seems to be an underlying problem with proj4:
echo "59 21" | proj "+init=epsg:3021" | invproj "+init=epsg:3021"
58d49'47.733"E 21d2'54.745"N
And that's without doing the datum shift part.

Hello Postgis Users!
This is my first post on this list so I will start by asking
a simple (and probably stupid) question. :)
While using ST_AsKml() to produce an overlay for Google Earth I
noticed that all my geometries where shifted slightly south-east.
I figured this had something to do with
Did you verify that the data in the shapefile is correct when you run the
command with just the table name?
Hang on a second... WHERE 'ID' < '20' is never true. That's why you're
getting an empty table. 'ID' is a string, as is '20'. I think you mean to
say where your ID column value is less th
Thanks for the replies, the most promising command so far is:
pgsql2shp -f [path] -h [myhost] -p [port] -u [user] -P [password] [database]
"SELECT * FROM table1 WHERE 'ID' < '20'"
Which has the output:
Preparing table for user query... Done.

Hi,

It is very interesting.

I will think the correct value was "3".
Certainly the value of coordinate used are of a 2D dimension.
But I don't understand w
