Geowarn - Geospatial Warning Systems - Nisyros Volcano, Greece

Quiescent but active volcanoes in regions of high geodynamic unrest represent a severe hazard and risk potential and require integrated monitoring, satellite surveying and data modeling.

Geodetic, seismic and geochemical monitoring data together with satellite images are transformed and unified in a coherent way to allow integration into a geographic information system (GIS). A completely new, interactive, and user-friendly software tool has been developed as a web-based multimedia platform encompassing a workflow of graphical 2 to 4D landscape models and all monitored data.




Several methodologies are applied in a completely new way to achieve the necessary results.
