| Geographic information services greatly contributed to the geographic information sharing, more and more enterprises or organizations have their own geospatial data and geographic information software features open for more people to enjoy the service.As the product of geographic information systems combined with the Internet, WebGIS has becomed one important development trend of geographic information services. With the number of geographic information services on the network continues to increase, fill the various needs of users increasingly, while a variety of services from different service providers, too scattered, different users need different data formats, and thus need to be integrate them together, Mashup technology can solve this problem effectively.This paper study Mashup ideas, system structure and personalized data integration technology, the major work is as follows:In different backgrounds, analyzed the research status of Mashup technology and development trends in a number of areas from two aspects,theoretical research and applied research,then discusses the basic theory Mashup,such as Mashup definition, characteristics, classification, pattern, composition, principle and developers used which technologies to build Mashup application frequently, pointed out in the development and application of Mashup is not a simple process to support data integration. Also introduces the case of Baidu Maps API and it’s libraries,spatial database storage and query technology, followed by a simple designe of geographic information service platform from the platform requirements and design, environmental build and feasibility of the plat form, finally use the public bicycle service in Wuhan City as a sub-platform service experiment. This experiment initially built an website that interface is more friendly, service is more convenient, the results of experiment show that the Mashup technology to build geographic information service platform is a direction worth trying. |
