SENSOR WEBS : A ROADMAP

Networks of sensors – interacting autonomously within its predefined conditions – are still a far vision of the new efforts called Sensor Web. The heterogeneity of sensor types, data formats, and communication protocols had lead to various distinct systems with very little interoperability in between. New efforts driven by the Spatial Data Infrastructure (SDI) community address those problems and provide interesting solution approaches. The Sensor Web Enablement initiative by the Open Geospatial Consortium aims at standardizing the entire sensor web process of sensor description, sensor discovery, sensor tasking, and access of data observed by sensors. This article will illustrate two important standing legs of current developments towards interoperable sensor webs: First the research questions addressed by research institutes and standardizing consortia, and second by open source software initiatives like 52north that help to bundle developer capacities and therefore accelerate the entire process to set up interoperable sensor webs, which are – despite all efforts – still in its infancy.
