I need to be able to store geographically keyed data and then select data from a specific geographical region, say a polygon (on the earth), to represent the user's field of view. Is there a (free) database technology that would allow me to do this kind of selection easily?

For a client-server database solution theres PostGIS, for a lightweight local solution theres SpatiaLITE. Both free and open source.
