Zusammenfassung
The future of the earth’s environmental systems will to a major extent be decided in cities as
already more than 50% of the population is concentrated there. Pervasively available sensors and
the data they generate can help to address pressing environmental challenges in urban areas by
making crucial information available to researchers and decision-makers. However, environmental
data is at present typically stored in disparate systems and formats, which inhibits reuse and
recombination. Furthermore, the large amounts of environmental data that stream in continuously
require novel processing approaches. So far, however, research at the intersection of
environmental sciences and urban data to overcome these barriers has been scarce. To address
these issues, we develop a novel framework using semantic web technologies. We apply
ontological concepts and semantic stream processing technologies in order to facilitate
combination, comparison, and visualization of heterogeneous data from various sources. The
platform for environmental data stream analysis introduced in this paper can inform and support
decision-making by non-expert users. We propose and discuss a three-step framework and outline
initial results.
