What are the advantages of using 3D over 2D to map a network?

Maps represent an abstraction of reality and are the most powerful tools to quickly provide information about places and spatial relationships to people searching for geographical information. The traditional 2D maps were designed for the non-digital age and the production of printed paper-maps. In the digital world there is however no reason for why to only operate in the two- dimensional world and not also include the third dimension. The user lives in a 3D world, and human beings have a more natural understanding of a 3D replication of the surroundings. A 3D map should therefore more naturally adapt to the surrounding environment of the respondents.
