Managing and integrating geography models in distributed environment

For the current "Model islands" problems which occur in the process of the geography modeling and model sharing, we propose an idea of geography model sharing and reusing method which based on the metadata standard in distributed environment. This article mainly solves how to describe and manage the geography model to achieve the model sharing and reuse. We work on the design of the metadata standard, the integrating standard and the managing environment of the geography model. It is expected to provide a convenient platform for the geographers, so that they can easily reuse any model, which means the heterogeneous models can be well shared.
