Advances in 3D Geoinformation Systems /by Peter van Oosterom (Author, Editor), Sisi Zlatanova (Editor), Friso Penninga (Editor), Elfriede Fendel (Editor) .This unique book focuses on comparing several types of 3D models. Due to the rapid developments in sensor techniques a vast amount of 3D data is available. Effective algorithms for (semi) automatic object reconstruction are required. Integration of existing 2D objects with height data is a non-trivial process and needs further research. The resulting 3D models can be maintained in several types of 3D models: TEN (Tetrahedral Network), Constructive Solid Geometry (CSG) models, Regular Polytopes, TIN Boundary representation and 3D volume quad edge structure, layered/topology models, voxel based models, 3D models used in urban planning/polyhedrons, and n-dimensional models including time. 3D analysis and 3D simulation techniques explore and extend the possibilities in spatial applications.
