Ontology of geodetic, cartometric and morphometric methods in the geoinformation environment

Summary The period of traditional measurements on analogue maps is coming to an end. This is being replaced by rigorous computer methods that will determine the metric properties of a feature with user-defined accuracy. The article proposes the research of conceptual and ontological models of geodetic, cartometric and morphometric methods in the geoinformation environment to provide a clear understanding of all instances and properties of these methods and to specify the requirements for the software product and its components. The ontological approach has provided a strict structuring of terms and concepts of the geodetic, cartometric and morphometric methods. It has ensured the creation of ontologies that define entities as the root classes of research and explore the relationships between them. The developed conceptual UML model and ontological model of geodetic, cartometric and morphometric methods in the geoinformation environment defines the entities and properties of these methods using CASE-visual design tool and Web Ontology Language.
