Geospatial Semantics and Ontology
The goal of the project "Building Ontology for The National Map" is to specify geospatial feature semantics for the Resource Description Framework (RDF) data model with the objective to translate traditional topographic information into a flexible spatiotemporal knowledge base toserve many different application areas.
The goal of the project "Ontology for The National Map" is to specify feature semantics for richer data models. New data models and associated knowledge organization systems for The National Map can translate traditional topographic information into a flexible spatiotemporal knowledge base that can serve many different application areas. Transformation of The National Map database into a comprehensive geographic knowledge base can bring new dimensions to topographic information delivery and revitalize the role of the USGS as the provider of trusted and consistent geographic information and a valuable geospatial integration framework. The USGS Center of Excellence for Geospatial Information Science (CEGIS) conducts research on topographic information, and will play a critical formative role in the development of ontologies, or knowledge bases, for topographic information.
A collection of publications and reports are available for specific information about geospatial semantics and ontology.
