Indoor location and navigation are fields of investigation that require a geographical information system to store information. Not only the layout of a building and navigation graphs, also the location of indoor beacons are important for such solutions. Inside a building, the problem to solve is very similar to air and sea transport, having the same objective: to position and guide a user through the venue.
Using indoormark tag it is possible to label several types of indoor beacons. The Ubica2 project developed by Zed with the collaboration of URJC is creating an indoor navigation system based on several indoor positioning technologies.
