OnGIS: Ontology Driven Geospatial Search and Integration
Popis výsledku v původním jazyce
Helping non-expert users to query over complex spatial data requires abstracting from GIS services and operations. This paper introduces an abstraction layer based on OWL ontologies. It provides an intuitive searching GUI for exploring data semanticallyintegrated from different sources. The language OWL 2 QL has been chosen as it performs open-world semantic web reasoning suitable for data integration, while having good computational properties. To support spatial constraints, a custom OWL 2 QL reasoner has been designed as part of this work. It allows relating different objects by means of spatial joins. A prototype system backed by the custom reasoner has been tested on the urban planning domain.
