"Visibility Analysis in a 3D Cadastre";
Talk: 4th International Workshop on 3D Cadastres, Dubai; 2014-11-09 - 2014-11-11; in: "Proceedings 4th International Workshop on 3D Cadastres", P. van Oosterom, E. Fendel (ed.); International Federation of Surveyors (FIG), (2014), ISBN: 978-87-92853-28-8; 183 - 196.

The implementation of a 3D Cadastre is work-intensive and expensive and legitimation of such expenses is necessary. A legitimate path of argumentation is that 2D systems fail to communicate complex legal situations correctly. Also, additional arguments can help to strengthen the position of 3D cadastres and provide support from other professions and social groups.
The paper is based on a newly developed model for 3D visibility. We discuss the model and how it can be used for two different application areas. The first is the assessment of property value, where the visibility or invisibility of specific objects can have a big impact. The other example is spatial planning. Spatial planning shall guarantee that cities are working economically and socially, that space is not wasted, and that the planned environment meets cognitive requirements. For example, evidences in spatial cognition show that visibility of landmarks is an important topic for tourism and navigation and should thus be addressed.
