Box 6, 7500 AA, Enschede, The Netherlands a r t i c l e i n f o a b s t r a c t Article history: This paper presents a method to assess the geometric quality of 3D building models. The quality depends Available online 2 February 2011 on properties of the input data and the processing steps. Insight in the quality of 3D models is important for users to judge whether the models can be used in their specific applications. Without a proper quality Keywords: description it is likely that the building models are either treated as correct or considered as useless Accuracy because the quality is unknown. In our research we analyse how the quality parameters of the input Analysis Three-dimensional data affect the quality of the 3D models. The 3D models have been reconstructed from dense airborne 2 Building laser scanner data of about 20 pts/m . A target based graph matching approach has been used to relate Lidar
