Abstract
Wireless Sensor Networks (WSN) as an infrastructure comprised of sensing, computing and communication elements are designed for the decentralized recording of environmental information. If the matter of concern is referenced geospatial information this in particular forms a Geo Sensor Network (GSN).
Recently there is an ongoing extensive impact of these new techniques on all geo sciences, whereby it depends on the application which demands with respect to data quality, size and costs of the sensor nodes, number of nodes in the network, requirements of the communication component (coverage, data throughput) and the power management are relevant. In Engineering Geodesy the new possibilities and new ideas emerging from GSN especially concern geo(detic) monitoring of objects like landslides or engineering construction sites. Theory and possibilities of GSN technology as well as some selected aspects for geo monitoring in particular will be discussed. As the early detection of already small variations is essential for Early Warning Systems (EWS) and risk management, data quality and reliability is of utmost importance. Thus, customary utilization of low cost equipment in such a GSN generally requires for calibration procedures and higher sophisticated evaluation concepts in order to provide meaningful results.
