Design and Implementation of Basin Water Environmental Information Sharing Platform Based on Geoportal

A set of techniques were studied for building a Basin Water Environmental Information Sharing Platform based on Geoportal against water environment information featured by multisource, isomerism, distribution and timeliness. Meanwhile, considering the current situation of information storing, management and use by the water environmental departments, a case of distributed sharing platform was built with the deign idea of service-oriented architecture (SOA). The platform could realize effective data integration of spatial data, attribute data and other formatted data, have the functions of registration, publishing, downloading and harvesting etc., of water environmental information, and provide a timely, accurate, credible data service for basin water environmental risk assessment and warning.
