e-sensing work presented at FOIS 2016 and GIScience 2016

New calculus for spatio-temporal event handling

The e-sensing project leader, Gilberto Camara, was invited to present a keynote lecture at the Formal Ontology for Information Systems (FOIS) conference, held in Annecy, in July. His keynote focused on dynamic geospatial ontologies for classifiction of events in land use change. This has also been presented at the GIScience conference 2016, held in Montreal.

Paper abstract

This paper presents the spatiotemporal interval logic formalism and shows how to use it for reasoning about land use change using big Earth observation data. This formalism improves our ability to extract information from large land remote sensing data sets.
