title: Wikimapia for Commercial Use
body: <p>Does anyone know of a mapping system similar to Wikimapia that can be used commercially.  Most importantly I need to be able to create areas/territories that cannot be modified by others and identify if an address is within a defined territory.</p>
  
  <p>I have seen Augur Maps which appears to do the same but when speaking to them they are currently not offering an API.</p>
  
  <p>Is one of the mega-APIs (Google, Yahoo, Bing, etc.) capable of doing this?  I came across something called geofencing in Google.  Is this something that could be used to define complex boundaries and verify addresses within the map?  Do the other providers have similar functionality?  Any examples/tutorials would be appreciated.</p>
  
  <p>TIA,
  Brian Enderle</p>
