Designing and implementing a geologic information system using a spatiotemporal ontology model for a geologic map of Korea

►ighlightsrn symbols mapped one-to-one with the spatiotempby a GIS representation. ► We standardized the spatiotemporal concepts of geologic map units. ► We developed a spatiotemporal ontology model of geologic map units. ► The proposed model is designed by W3C Time and OGC GeoSPARQL. ► We implemented a spatiotemporal retrieval system by applying our geo-ontology model.
