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: http://postgis.refractions.net/docs/ch04.html#id2524285 Cheers, Carlos del Cacho -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Tobias Nothdurft Sent: martes, 28 de noviembre de 2006 14:59 To: GEOS Development List Subject: Re: [geos-devel] troubles understanding GEOS Hi. > If you want to use the quadtree-functionality of GEOS for some goemetry > processing, you don't need PostgreSQL and PostGIS at all. > > GEOS is just a geometry processing library, geos by itsself doesn't do > anything with databases. > > You can use PostGIS/PostgreSQL for storage of your geometries, or > GDAL/OGR, but you don't have to. 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?
