A theory for event processing of geosensor data

Abstract

Event processing allows to analyze huge amounts of data streams in real-time. Some environmental applications dealing with sen- sor data need to perform geoprocessing and respond to time-sensitive issues. The application of event processing methods to geosensor data without having into account the implicit spatiotemporal setting of the observation process may lead to inaccurate results. Spatial attributes are important to infer relationships among environmental occurrences. This paper presents a simple theory to deal with sensor observations as geospatial events.
