摘要:

资源与环境信息系统中数据的元数据标准业已产生,但对于数据使用十分重要的模型与方法元数据尚未有完整的描述,本文提出并分析了模型与方法元数据的概念与内容,同时针对近年提出的地理信息服务,提出了模型与方法元数据的服务模型,以实现对模型与方法的有效管理与分发服务,并得出在资源环境信息系统中基于模型与方法元数据的地理信息服务是切实可行的结论。

Abstract:

The metadata standard of data in resources and environment information system (REIS) has been created. As for the model and method metadata, which is very important to the usage of data, it has not been described in detail. So we put forward the idea and the concept of the model and method metadata, also advance a service model for the model and method metadata in order to realize efficient management and distribution for service of the model and method. Finally we draw a conclusion that it is feasible to realize the GIS service based on the model and method metadata.
