-Ontologies of the geographic world 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. ​These entities ​are not merely located in space, they are tied intrinsically to space. ​To properly ​capture ​changes, it is also necessary to describe events and processes. 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.+Ontologies of the geographic world 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.
