paragraph_text: Land navigation
  
  Navigation for cars and other land-based travel typically uses maps, landmarks, and in recent times computer navigation (" satnav ", short for satellite navigation), as well as any means available on water.
  
  Computerized navigation commonly relies on GPS for current location information, a navigational map database of roads and navigable routes, and uses algorithms related to the shortest path problem to identify optimal routes.
  
  Pedestrian navigation is involved in orienteering, land navigation (military), and wayfinding.
