Abstract: Laser scanning has become the standard technique for the acquisition of digital elevation models. With the increasing point densities point clouds acquired by laser scanning have the potential to also become valuable data for the production of three-dimensional topographical databases. This paper discusses the possibilities to use airborne laser scanning for two tasks: change detection and semi-automated 3D mapping of urban environments. While laser scanning is demonstrated to be useful for detecting changes as well as mapping errors, the imple...
