Dustin,

Just a tip.  You might want to try OpenJump as well.  We use the editing
tools for sketching out things on top of our map and it can output to WKT,
GML and also save to PostGIS / ESRI shape etc. though I usually use the WKT
window and the adhoc querying capability it has.

We are going to be demoing it in our PGCon2009 presentation.  Check it out.

Thanks,
Leo

Chris,

That's very helpful thanks!  I read the first chapter of Regina's book and
purchased the e-book version for the rest.  Been playing with Google Maps to
draw out my "zones" using their draw tools.  Now going to use the RSS feed
of those maps to get those geometries in a postgis database.   Moving in the
right direction, finding this GIS stuff very interesting.

Thanks Again,
Dustin
