Exploration for the surveying of the “Kammstollen” between the Schneefernerhaus and the Kammhotel at Zugspitze as preparation of a joint measurement campaign for the monitoring of mass displacements related to local hydrology applying gravimetric, geoelectric and seismic methods. The position of all geologic and gravitational measurement points shall be determined with an accuracy of less than 5 cm by geodetic surveying. These are approximately 175 points on a length of about 800 m. The surveying will take place on 20.-21.05.2014, followed by several joint measurement campaigns during this year.
