| Abstract: | Based on reviewing three-dimensional geographic information system (3D GIS) technology, an information management and prediction system for urban land subsidence is designed on the basis of GIS technology. The detail of design thought, function and structure of the system is introduced. The authors proposed a series of blue print for key problems when constructing the system, such as the principle for choosing land subsidence modeling based on porous water migration, the process of 3D land subsidence modeling and its volume visualization supported by the mixed data model and three layers structure for the information broadcast function of the system through Web, etc. |
