Many kinds of environmental data are nowadays publicly available, but spread over the web. This article discusses using the Sensor Observation Service ( SOS ) standard of the O pen G eospatial C onsortium ( OGC ) as a common interface for providing data from heterogeneous sources which can be integrated to a user tailored environmental information system. In order to allow for providing user‐tailored and problem‐specific information the adjusted SOS is augmented by a semantic layer which maps the environmental information to ontology concepts. The necessary information fusion from different domains and data types lead to several specific requirements for the SOS . Addressing these requirements we have implemented a SOS which still conforms to the OGC SOS 1.0.0 standard specification. The developed SOS has been integrated in a publicly available demonstrator of our personalized environmental information system. Additionally this article discusses future consequences for the SOS , caused by the recently published SOS 2.0 specification.
