Faculty OTB Research Institute for the Built Environment Department OTB Research Date 2013-02-28 Abstract Level of detail (LoD) is a concept available in various disciplines from computer graphics and cartography to electrical circuit design. For GIS practitioners, the discipline where level of detail is most relevant and well known is 3D city modelling. While present LoD paradigms, such as the one found in CityGML, fulfil the requirements of many applications, there are significant shortcomings: the levels are discrete and their number is limited, potentially there is inconsistency between different LoDs, the paradigms do not take into account the application and user’s needs, and redundancy is present in virtually all parts of the modelling-storage-query-visualisation workflow. This PhD research aims to improve the concept of level of detail in 3D city modelling through (1) its formalisation in a definition, (2) modelling it as a spatial dimension, i. e. in a space-scale hypercube, (3) definition of contexts with use-cases which take into account the environment in which level of detail are needed, and (4) generation of pseudo-continuous levels of detail which are customised for an application or for general use. This research will be conducted over a period of 48 months with a dissertation as its principal deliverable.
