Geocaching is an entertaining adventure game for GPS users where somebody hides a cache and others try to find it. Virtual geocaching is very similar but it runs virtually. All that you will need for it is MapSphere and a bit of luck. After you have registered and logged-in to MapSphere Online you can start seeking for virtual caches immediately. Among other improvements of MapSphere Online: you can follow another user by repeating its track, you
can send other users links and place marks in a chat window. For the list of new features, click here. |
