Abstract: Geospatial ontology development and semantic knowledge discovery
addresses the need for modeling, analyzing and visualizing multimodal information, and is unique in
offering integrated analytics that encompasses spatial, temporal and thematic dimensions of information
and knowledge. The comprehensive ability to providing integrated analysis from multiple forms of information
and use of explicit knowledge make this approach unique. This also involves specification of spatiotemporal
thematic ontologies and populating such ontologies with high quality knowledge. Such ontologies form the
basis for defining the meaning of important rela-tions and terms, such as near or surrounded-by, and enable
computation of spatiotemporal the-matic proximity measures we define. The ability to automatically and
semi-automatically extract metadata from heterogeneous, and multimodal data from diverse sources with
unstructured, semi-structured and structured data, while exploiting relevant ontologies and associated
knowl-edge bases, form the basis for analytics.
