Possibly easier, for most US cities, is taking advantage of the fact that the roads are on a predictable grid. You just need the GPS coordinates of three intersections (four if you want to be paranoid for the projection) and you can infer the location of anything within the grid from the address. The nice thing about this is (a) someone might already have the coordinates for some addresses online (many stores do, on their websites, for example) and (b) someone you know might live _somewhere_ in the grid and own a GPS or even (c) around the perimeter of the grid, buildings are much smaller. _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
