The vision of a digital earth calls for more dynamic information systems, new sources of information, and stronger capabilities for their integration. Sensor networks have been identified as a major information source for the digital earth, while semantic web technologies have been proposed to facilitate integration. So far, sensor data is stored and published using the observations & measurements standard of the Open Geospatial Consortium (OGC) as data model. With the advent of volunteered geographic information and the semantic SensorWeb, work on an ontological model gained importance within Sensor Web Enablement (SWE).
