[geos-devel] Planar point location query?

That's a pretty easy question Charlie, and almost any spatial  
framework at all will answer it.  Whether GEOS is the tool for the  
job depends on what your larger architectural context is.  Is the  
question always going to be that easy, or will it get harder, larger,  
more frequent?  Would the flexibility of a database help?  If time-to- 
deployment is an issue, either using PostGIS and SQL as the  
interface, or Mapserver and the Mapserver CGI as an interface can  
give you a system that answers that kind of a question in half an  
hour or less of setup.
