Web Services Based GIS Model Sharing Service

Nowadays, sharing is one of the most frequently hot topics. Compared with adequate data source and data share, it is more important to use the abundant data. Generally, a geographic information system (GIS) consists of two parts which are data and function. Sharing function is a good way to make the data usable. For this purpose, we set up the architecture for GIS model sharing. Furthermore, an archetype system is built to prove the feasibility, and an environment evaluation model is used for a test on Beijing and surrounding areas. The archetype system shares the environmental evaluation model via Web services. It enables end users to combine local data and remote function together to execute environment evaluation and analysis. The archetype system is a proof of the feasibility of the GIS model sharing architecture. The environment evaluation result generated by the archetype system is consistent with the ground truth. It is more convenient to use the archetype system and it also reveals the utility of Web services based GIS model sharing service. However, the archetype system needs to be improved in many aspects.
