ABSTRACT

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