摘要:National geologic map databases are presently being constructed in the U.S. and Canada, as well as in several other countries. Here, we describe an object-based model for geologic map information, specifically designed to represent digital geologic maps and related geoscientific information. Although oriented to geoscience, several fundamental issues in representing geospatial information are explored in this design, including the philosophic and cognitive basis of mapping in general, and the overall framework in which map-related information can be represented. Thus, we take an ontologic approach to geo spatial representation, supplemented by an epistemic view of the scientific process, which culminates in a very general model—a meta-model—for map informatio n. Practical as well as theoretical considerations mo tivate this approach. Primarily, ho wever, we describe the theoretical foundations o f our meta-model, specifically semiotics, category theory, and ontology in geospatial information. Finally, we report briefly on a specific prototype data model derived from the meta-model and implemented in a commercial object-oriented GIS
