New Challenges for 3D City Models - focus should be on Interoperability and not Verisimilarity

tele-TASK-Aufzeichnung des Vortrags  

3D city models have become a very popular commodity for cities in general. The politicians and/or the administrative management have in the last few years been very active when it comes to investments in dimensionality, and the models come in many different forms and for many specific or non-specific purposes. The trend until now has shown that municipalities and developers in most cases have given high priority to the visual impact of these models. It has been more important for the cities to obtain a model that gave a high degree of verisimilarity in contrast to a model that had a high degree of interoperability. Verisimilarity would in this case mean a 3D model with close resemblance to reality and based on modelling principles from CAD and scenes from this build with focus on photorealism. Interoperability would mean a 3D model that included semantics in form of an object model and an ontology that would make it useful for other purposes than visualisation. Time has come to try to change this trend and to convince the municipalities that interoperability and semantics are important issues for the future. It is important for them to see that 3D modelling, mapping and geographic information are subjects on the same agenda towards an integrated solution for an object-oriented mapping of multidimensional geographic objects in the urban environment.
