An Object Model for Geologic Map Information
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 e...
متن کاملSpatial and Temporal Reasoning in Geologic Map Interpretation
A rcccnt trend in cxpcrt systems rcscarch has been toward systems which reason from descriptions of causnl processes in the domain, rather than from the surface cffccts. ‘I’his is the “causal model” versus “cinpirical association” distinction prcscntcd in [2]. Typically, this involves creating a dctailcd model of the physical proccsscs which undcrly the domain. ‘I’his model must support infcrcn...
متن کاملSemantic Mediation in the National Geologic Map Database (US)
Controlled language is the primary challenge in merging heterogeneous databases of geologic information. Each agency or organization produces databases with different schema, and different terminology for describing the objects within. In order to make some progress toward merging these databases using current technology, we have developed software and a workflow that allows for the “manual sem...
