[geos-devel] troubles understanding GEOS

[Del Cacho, Carlos (Carlos)]

PostGIS may be sufficient for what you want to do.

Just remember you cannot create spatial columns through CREATE statements,
use AddGeometryColumn instead:
http://postgis.refractions.net/docs/ch04.html#id2523380

And... you need to create a spatial index on the geometry column for
enhancing query speed:

Cheers,
Carlos del Cacho

I see!

But there has to be a gain to link my programm with some kind of database
when i
have to handle hundreds or thousands of objects! :) So how do I accomplish
this
connection? With the WKT-reader and -writer?
