The concept of a “Digital City” is playing an important role in urban planning and 3D city models are the basic components for such ideas. Manual 3D model reconstruction is time consuming and expensive, but Lidar provides a more efficient way to capture 3D data with millimeter resolution allowing for better accuracy and an more automated reconstruction; traditionally, city models are manually build based on city blueprints and aerial images, with lidar however, city models can be generated from lidar data automatically.
