A Future Sensor Web for the Environment in Europe

Initially the Sensor Web was defined as a web of physical sensors or sensor networks (Di, 2007).

A second extension, encapsulating citizen as sensors, was proposed recently (Goodchild, 2007). Today, numerous use cases for each of these three aspects of the Sensor Web are available to environmental sciences; these include environmental monitoring, emergency response systems, air and water quality, health, and transport...JRC.DDG.H.6-Spatial data infrastructure
