Adapted Rules for UML Modelling of Geospatial Information for Model-Driven Implementation as OWL Ontologies
Jetlund, Knut; Huang, Lizhen; Onstein, Erling (Journal article; Peer reviewed, 2019)This study aims to improve the implementation of models of geospatial information in Web Ontology Language (OWL). Large amounts of geospatial information are maintained in Geographic Information Systems (GIS) based on ... -
Harmonizing and linking conceptual models of geospatial information: Technologies for information modelling in GIS, ITS and BIM
Jetlund, Knut (Doctoral theses at NTNU;2021:135, Doctoral thesis, 2021)Structured representations of phenomena from the real world in a digital geospatial environment are essential for developing, maintaining, and using the built and natural environment. In the real world, the phenomena relate ... -

Jetlund, Knut; Onstein, Erling; Huang, Lizhen (Peer reviewed; Journal article, 2020)This study aims to improve the interoperability between the application domains of Building Information Modelling (BIM) and Geographic Information Systems (GIS) by linking and harmonizing core information concepts. Many ... -
Improvements in automated derivation of owl ontologies from geospatial uml models
Jetlund, Knut (Journal article; Peer reviewed, 2018)Standards from ISO/TC 211 are the foundation for modelling a universe of discourse in a geospatial context. UML models based on the standards, and in particular based on the UML profile defined in ISO 19103, have been ... -
Information exchange between GIS and geospatial ITS databases based on a generic model
Jetlund, Knut; Onstein, Erling; Huang, Lizhen (Journal article; Peer reviewed, 2019)This study aims to improve interoperability between Geographic Information Systems (GIS) and geospatial databases for Intelligent Transport Systems (ITS). Road authorities maintain authoritative information for legal and ... -
