Evaluating the geometric aspects of integrating BIM data into city models

• Airborne Laser Scanning (ALS) is used to acquire three-dimensional(3D) city model data over large areas. However, because of the longALS update cycle, building information models (BIM) could be utilizedto maintain city models. In this study, we designed, implemented, andevaluated a methodology to formalize the integration of BIM data intocity models. CityGML models were created from BIM data and ALS/footprint data based on common modelling guidelines. Both CityGMLbuilding models are modelled in a similar way and the relative differencesbetween the models are on the order of decimetres.
