| The development of geography spatial data processing technology promoted the continue expanding of GIS applications, and has led the peoples’needing of sharing spatial data. WebGIS changes its designing model of system constantly as the development of network technology. GIS technology has formed different genres because of different application fields, and different departments formed its respective develop mode. The diversification of spatial data format and different storage methods has become the bottleneck in the development of data sharing in the environment of network.This article focusing on the research of processing methods of spatial data based on the analysis of traditional WebGIS develop pattern, put forward the method of using the metadata thought to solve the access of multi-source data, discussed the independent storage method and interpolation analysis method for vector data.This paper describes the design of spatial database in detail, studies the program of integrating the spatial data engine and spatial analysis module into the GIS application server. Finally put forward the designing structure of the overall system of WebGIS, and discusses the feasibility of applying the system into the army’s construction of information. At last, a simple experiment was carried out for the simulation of the system, where the design of the system is verified to meet the needs of users and has certain value of promotion. |
