Beside the specific research data, the Institute of Cartography created a database for
large topographic datasets in order to support the seismological research activities of the
project. Such datasets are for example Geological Maps (scale 1:25000), the Digital Terrain
Model (scale 1:25000), and satellite imagery (SPOT and LANDSAT) for the entire
Switzerland. In addition, within the cooperation with the SwissExperiment project, the
COGEAR topographic database is being enriched with the newest products of the Swiss
National Mapping Agency, namely two height models of the surface and terrain (DOM and
DTM-AV) and the high resolution airborne imagery Swissimage25. DOM and DTM-AV
are high-precision modelling of the earth's surface below 2000 m based on high precision
laser scanning from aeroplanes. Swissimage is a high resolution orthophoto mosaic taken
with an airborne digital camera and having a ground pixel size of 25 cm.
The live sensor data is managed through Global Sensor Networks (GSN). GSN is a
software middleware designed to facilitate the deployment and programming of sensor
networks. It is a Java environment that runs on one or more computers composing the
backbone of the acquisition network. A set of wrappers allow feeding live data into the
system, while data streams are processed according to XML specification files. The system
is built upon a concept of sensors (real sensors or virtual sensors) that are connected
together in order to built the required processing path. Real sensors refer to live data
streams while virtual sensors are used if the data is already stored automatically as files or
in a database (GSN, 2010).
