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 provide 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 relations and terms, such as near or surrounded-by, and enable computation of spatiotemporal thematic prox-imity measures we define. SWETO (Semantic Web Technology Evaluation Ontology) and its geospatial extension SWETO-GS are examples of these ontologies. Two enabler for what we term geospatial analytics (GSA) are (a) the ability to automatically and semi-automatically ex-tract metadata from syntactically (including unstructured, semi-structured and structured data) and semantically heterogeneous and multimodal data from diverse sources, and (b) analytical processing that exploits these ontologies and associated knowledge bases, with integral support for what we term spatiotemporal thematic proximity (STTP) reasoning and interactive visualiza-tion capabilities. This chapter covers results of our geospatial ontology development efforts as well as some new semantic analytics methods on this ontology such as STTP.
