This research includes three parts of sob-topics. They are: 1) Describing methodology of geo-spatial information modeling; 2) Integrating geo-spatial information and digital maps using 3D GIS; 3) Using ground-based LiDAR to survey and map 3D buildings in order for the dynamic environmental modeling. Three main objectives have been fulfilled. They are: 1) Modeling geo-spatial information and implementation: 2) Combining air photos and DTM to construct 3D virtual environment; 3) Utilizing technology of computer graphic visualization to promote surveying rapidity of 3D models and enhance visual simulation of geo-spatial reality.
