I've merged my work with revision 1323 of sroebert. This is an upgrade because sroebert created an omnimap layer for USARSim. I've committed my work fused with sroeberts version as revision 1879. I've done some tweaking and trying to come up with new filter methods because the techniques I used so far aren't working. I've made a filter saying that something is considered free space if N pixels after it are also free space. This didn't give a cleaner view of the map. I'm going to come up with some new techniques tomorrow.
