Description:

Southern Poland, especially Polish Carpathians, is a region affected by strong mass-movements. The importance of massmovements problems has been taken into consideration on the governmental level and Landslide Counteracting System (SOPO) program was launched in 2008. The main purpose of this program is to create inventory and map all active and inactive landslides and landslide prone areas in Poland. However, in case of such gigantic work, the traditional mapping methods meet sometimes their limitations. In order to overcome some of efficiency problems the new technology, the application of airborne laser scanning was tested. The main purpose of presented work is to test whether the LiDAR DTM is capable to support geological interpretation and landslide detection on steep and forested slopes for the purposes of landslide mapping within SOPO project. For this purpose the ALS dataset covering 40 km2 of the area near Roznow Lake in Polish Carpathians have been acquired in April 2010. The average scanning resolution was 7 points/m2 and LiteMapper 6800i system based on the full waveform, Riegl LMS-Q680i scanner have been used. Acquired point cloud was applied to generate DTM of 0.5 m resolution. For efficiency test purposes the detailed geological interpretation of constructed ALS DTM was focused on already well mapped large Zbyszyce landslide. The extents of the landslide and the zones of different level of activity have been mapped and then verified with field data. During the detailed analysis it was found that the level of the details of ALS DTM allows also performing morphometric analysis on landslides., Andrzej Borokowski, Zbigniew Perski, Tomasz Wojciechowski, Grzegorz Jóźków and Antoni Wójcik., and Obsahuje bibliografii
