Geodetic Basis used during the Remediation of Strečno Cliff

Abstract

Great part of Slovak traffic is led by the highways nowadays. There is a number of critical parts in highway from Bratislava to Košice, the most critical is under the castle Strečno. In the future, there are plans to redirect the traffic during the tunnel, but in present the traffic goes through road I/18. This is placed between Váh River and the castle, which is placed on the cliff above the road. The flooding and the gradual collapse of cliff accompanied by falling of rock pieces on the communication is very dangerous. The access on the castle walls is almost impossible, it is necessary to use new technologies. The imagining was done by UAV equipment Microkopter and uncalibrated camera with CMOS Full Frame. The result of the work is photoplan with dangerous parts overdrawn. These can be helpful during the remediation.
