Geography Spatial Data Processing Technique Of Boundary Information System

Boundary information system is a comprehensive aplication geography information system. The complexity of boundary also decides the complexity of the boundary geography spatial data, The processing of a great deal of boundary geography spatial data can even develop system for the usage boundary information system in physically the application of function. The article discussed the boundary geography spatial data processing technique method and the application systematically:At first,it introduces the boundary geography spatial data processing to develop foundation boundary information system. And it explaines the function of data processing technique in that system, makes a preparation work for next work.Secondly it introduces the boundary geography spatial data processing to develop foundation boundary information system. And it explaines the function of data processing technique in that system, makes a preparation work for next work.Thirdly the obtain and data model in the boundary spatial data,it introduces spatial data model of the boundary information system and analyzes the spatial data model.Finally application and processing in the boundary spatial data. Carried on the analysis and design to the importation and exportation mold piece of the data. Introduced many sources and processing technique of spatial data,including reprocessing,compress and cut of image.The paper in the end concludes the research results and the further research problems, and carries on the prospects.
