Hi, > It should be good to find a generic interface that file drivers must implements
What about something similar to MVRTreeMap? We could define an interface. Then, I guess we might be able to create an "adapter" that internally uses both DBF/SHP files and the MVRTreeMap, overlaid, like UnionFS: http://en.wikipedia.org/wiki/UnionFS Regards, Thomas On Tue, Jul 30, 2013 at 10:07 AM, Nicolas Fortin (OrbisGIS) < [email protected]> wrote: > > Yes.
