Modeling visibility through visual landmarks in 3D navigation using geo-DBMS

Today’s map navigation systems (from 2D to 3D) provide direction instructions in the form of maps, pictograms, and spoken language. However, they are so far not able to support or has very limited access to landmark-based navigation, which the most natural navigation concept is for humans and which...
