We present XGSN, an open-source system that relies on semantic representations of sensor
metadata and observations, to guide the process of annotating and publishing sensor data …

Pervasive and sensor-driven systems are by nature open and extensible, both in terms of
input and tasks they are required to perform. Data streams coming from sensors are …

Measuring biodiversity simultaneously in different locations, at different temporal scales, and
over wide spatial scales is of strategic importance for the improvement of our understanding …

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 …
