Research on shared platform of water environment information services based on GeoGlobe

GIS is widely used in many fields and various industries, which makes sharing and interoperability of geographic information become urgent requirements of all departments in network environment. In the application field of water environment, some analysis systems of water environment have appeared. However, these systems often work in single computer, and their characters of common sharing are poor, besides, the maintenance and update for them is more difficult; Also, occurred some analysis services of water environment based on web services, but usually these services are dispersed and have less function, so it has much more difficulties to find and use them. This causes the contradiction of information asymmetry between the providers and the users of the services. Because single service barely satisfies the complex requirements of the users, it is a problem to be solved that how to integrate these single service into service chains which will meet the needs of broad users; At the same time, after constructing the service chains, it is also a problem needed to be solved that how to make users find the chains simply and show the results of the calls of these service chains. Aiming at these problems, this paper presents the shared platform model of water environment information service based on GeoGlobe (hereinafter service platform of water environment). This platform is put up on the basis of GeoGlobe, as a sub module of GeoGlobe. This platform provides a better solution for the above problems. The service platform of water environment is just like a store whose commodities are various information services of water environment. If we say that the appearance of stores satisfy the needs of everyday life, well then, we can say that the occurrence of the service platform of water environment satisfies people's work needs in the area of water environment. This paper can be mainly divided into two parts: One is the building of the service platform of water environment, which contains the constructing of service chains, the registry of the chains, visual displays of information and so on; The other is to show the validity and feasibility of this paper's work, combined with the practical work item (namely “water evaluation service”), which is built using the service platform of water environment.
