Study And Research On The Geological Project Management System Based On 2D/3D GIS Technology

Geological prospecting is the foundation and stratagem work for the national aeconomy construction. Its quality directly impacts the persistence and healthy of the national development. Since the establishment of the PRC, all levels governments have pay out vastness manpower, material resources and financial resources in this aspect, especially along with high speed of the market economy and increasingly innovation and opening. Using 2D/3DGIS, WebGIS technique to process the geological projects management problem spatial information can be titled as the focus problem in this field. Some commonly encountered issues in the processing were studied as a special topic in this essay.Firstly, from the actual logic need and the data security of the geological projects management work, the technique framework design of the task system, combined with the morden WebGIS and 3DGIS technology, was abstracted in chapter 2.Then, because of the information of the geological projects involves the project management, geological prospecting data and government policies etc. and all this kind of data are not essential for the task to research on. For the convenience of study, after discuss on the relationship in various geological projects and relationships to the management, a more commen data model was finally put forward. This made a basement for further study.Based on the abstracted data model, associated with the technique framework mentioned above, geological project data organizing and sptial database design was discuss as a special topic. It mentioned the basement spatial data orgnizition, geological project spatial data processing and also the projection coordinate system problem etc.The national government and every local province govment have special requirement on the geological project data submission. In the task system framework, the'Project Data Submintion'subsystem, using the deskpro and C/S combining structure, felicitously solved this problem and described through an example. It was one of main aspect of this essay.Currently,ArcGIS Server9.3 is the most classic and advanced platform in GIS field and the REST Service framework is the most convenience one to imply on. Microsoft Silverlight was used in this Service framework and is the crucial and difficult problem in the WebGIS subsystem. And also it is one of this essay's emphases.Finally this paper emphasize studied the 3DGIS technique. 3DGIS is a currently advanced and hot technology in GIS field. The author standed out the two platforms: ArcGIS and SkyLine to make explor. After that, the technique difference and stand or fall between these two platforms was pointed out, and this also was as the basic reason to do the technique selection. Afer all the implement which combined with SDE was described in the essay.Using 2D/3DGIS,WebGIS to realize the geological projects management, geological project data organizing and the task system implyment is the technique innovations of this essay.
