Introduction to Geoinformatics: Classes 2016


This course is focused in the ontologies of the geographic world, that are important to allow the sharing of geographic data among different communities of users. A geo-ontology provides a description of geographical entities, which can be conceptualised in two different views of the world. The field view considers spatial data to be a set of continuous distributions. The object view conceives the world as occupied by discrete, identifiable entities. Objects and fields are not merely located in space, they are tied intrinsically to space. However, to properly represent changes, it is also necessary to describe concepts that convey the dynamics of spatial phenomena. The notions of events and processes are useful to explicitly include the temporal dimension. The lectures present a general overview of the main trends in Geospatial Ontology, discussing the concepts of objects, fields and events for representation of geographical phenomena. The course also highlights the specific area of land use and land cover ontology, an area of considerable importance for geospatial ontology research.
