Geographic Feature Type Ontology

Some Core Notions

• Focus on Human-Geo-Space
• Granularity is key
• extent versus dimensionality
• The ontology should be a mid-level ontology
• particular types of geometry make only sense if they match particular relations on the semantic level, e.g., containers/containment
• affordance-based classification versus property-based, e.g., navigable versus manmade
• examples, e.g., nations versus countries in ADL compared to TGN
• ADL, freebase, dbpedia, geonames, TGN,....
• map between existing geo-ontologies (e.g., matching, aligning, similarity, sameAs,...)
