      abstract     = {The Sensor Web provides wider access to sensors and their
                      observations via the Web. A key challenge is to infer
                      information about geographic events from these observations.
                      A systematic approach to the representation of domain
                      knowledge is vital when reasoning about events due to
                      heterogeneous observational sources. This article delivers a
                      formal model capturing the relations between observations
                      and events. The model is exploited with a rule-based
                      mechanism to infer information about events from in-situ
                      observations. The article also describes how the model’s
                      vocabularies are used to formulate spatiotemporal queries. A
                      use case for reasoning about blizzard events based on real
                      time series illustrates the formal model.},
