This paper delivers an ontology to formally capture the relations between observations and geographic events. The ontology constitutes common building blocks for constructing application ontologies that account for inferences of the former from the latter. The formal vocabularies are exploited with a rule-based mechanism to support inferences of events from in-situ observations. The paper also demonstrates how these vocabularies are used to formulate symbolic spatio-temporal queries in the Sensor Web. A use case for reasoning about blizzards and their temporal parts from time series supplied by the Environment Canada illustrates the ontological approach.
