Study On Visualization Technology Of Surficial Subsidence Information Based On MAPGIS

The dissertation mainly studies the visual management technology of the surface subsidence information caused by mining, direct against the poor situation of the visual management of the coal mining enterprise modern information, especially the visual management of three-dimension(3-D) mining information, in our country. A 3-D visual study model is put forward by studying visual information technology, which based on the information caused by mining. With the organic combination of MIS and GIS, using the secondary development components and function classes provided by MAPGIS, a visual information management system is developed, which combines multiple technologies, such as GIS, multimedia, database, visual reality, and so on.In the system, the information caused by mining, including spatial and non-spatial data, can be input/output, processing and updating timely, the display and analysis of 3-D block derived from surface subsidence data, the production of section map and the demonstration of 3-D simulation topography. The system is reliable to work and easy to use. It realizes the visual and intelligent management and application of the surface subsidence information, provides the ocular demonstration of the data for the user and provides the technology means for the safe production and correct decision of the coal mining enterprises.
