Hmm... this sounds like a WPS (Web Processing Service) application, though how this needs to get implemented depends a lot on the data structure. You may get away with a simple proximity query if you use the "querylayer" extension, though it won't tell you if a building is right or left and might intercept unrelated buildings at crossroads. http://docs.geoserver.org/latest/en/user/extensions/querylayer/index.html Cheers Andrea > Reagrds, > > Marwa Elsaid > > ------------------------------------------------------------------------------ > EMC VNX: the world's simplest storage, starting under $10K > The only unified storage solution that offers unified management > Up to 160% more powerful than alternatives and 25% more efficient. > Guaranteed. http://p.sf.net/sfu/emc-vnx-dev2dev > _______________________________________________ > Geoserver-users mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/geoserver-users > > -- ------------------------------------------------------- Ing.
