Thomas J. Jerris Dalia E. Varanka 2015 <p>Semantic ontologies are examined as effective data models for the representation of complex topographic feature types. Complex feature types are viewed as integrated relations between basic features for a basic purpose. In the context of topographic science, such component assemblages are supported by resource systems and found on the local landscape. Ontologies are organized within six thematic modules of a domain ontology called Topography that includes within its sphere basic feature types, resource systems, and landscape types. Context is constructed not only as a spatial and temporal setting, but a setting also based on environmental processes. Types of spatial relations that exist between components include location, generative processes, and description. An example is offered in a complex feature type &lsquo;mine.&rsquo; The identification and extraction of complex feature types are an area for future research.</p> application/pdf en Complex Topographic Feature Ontology Patterns text
