Project description Building on the capacities of airborne laser scanning (ALS), a technology for quickly producing a high-resolution, 3D scan of the ground surface, numerous production methods for the collection of geodata have been established. The expansion of existing geodata is the new challenge of small and medium-sized enterprises and administrators working in this field. The laser data promise a great potential for directly detecting 3D changes. The goal of this project is to develop methods of expanding the scope of existing geodata based on ALS. Continuation requires a decision as to which data sets or parts of data sets (for example in DSM) are to be kept, removed or changed. Solutions for point-based and for object-based change detection and continuation of a geodata set collection in equal measure are to be found and tested for their applicability in use with large data sets. Color pictures or multi-spectral pictures that can be simultaneously recorded with new laser scanners are also to be taken into consideration when building models and with automated decision making.
