Abstract :
Geo-information network service has become more and more popular; however the practical application of vector data service is rare used. The main reasons are as follows: firstly, with the variety of vector data formats, the general format conversion cannot be applied data shared services; Secondly, Existing vector data service interface standard (such as WFS) is too simple, which doesn´t meet the complex practical application; thirdly, with a lot of CPU-treatment needed, vector data service result in performance bottlenecks, which cannot meet the needs of practical applications; in addition, as vector data contains a large number of coordinates, and the previous technique cannot guarantee good service security, the vector data service is difficult to promote. This paper will solve these problems based on WCF framework.
