Application of scanning technology in cliff shores monitoring

Abstract

So far geodetic surveys of cliff shores were predominantly conducted with 3D coordinates of the upper edge and the bottom of a cliff slope. Thus, there is a possibility to use modern reflectorless survey techniques to monitor the entire surface of a cliff slope, including the inaccessible areas. The use of this technique allows automatisation of surveys with high accuracy and short time of observations. This paper presents the application of the scanning tacheometers to monitor a cliff of Baltic Sea near the Pleśnia village in Poland. It also presents the methods of visualisation of survey with DTM using TIN and GRID types..
