Abstract:

This paper introduces the fundamental concept, conceptual schema, and the method of resources and environment information classification and coding, and describes the data layer organization, conceptual database, and the logical database of national resources and environment scientific database initiative. It then explores the application schema of resources and environment scientific database by optimization and integration of several thematic resources and environment and geographic information classification and coding scenario. The paper also illustrates the GIS-oriented geographic information classification and coding offers an important solution to the geospatial data coverage arrangement and structure construction of attribute data file in conceptual level, also an important approach for data sharing and semantic interoperability between different applications. Finally, the paper concludes by presenting some aspects of resources and environment information classification and coding, and also suggests the further work on this domain.

Key words: resources and environment information, classification and code, conceptual schema, application schema
