In the southern part of the O´swi˛ecim Basin, in the Ko´nczyce Wielkie gravel-pit, we can find outcrops of Quaternary deposits with varied geological histories. The lower fluvial sequence is covered with glacigenic sediments. The glacigenic deposits occurring below the Brunhes-Matuyama boundary and interglacial sediments are older than the Cromerian Complex. This ice-sheet advance, in its maximum extent in southern Poland, is correlated with the Günz, i.e. pre-Cromerian glaciation in Western Europe. Cultural material was located within fluvial sands with fine-grained gravels, below a layer of diamikton – interpreted as till – and underneath the boulder pavement – an equivalent of diamikton. Raw materials inventory include local flint and hornstone, foreign flint, hornstone, quartzite, opalite, gneiss granite. Among the artifacts are macrolithic and microlithic cores, flakes and tools. The pebbles, flakes and microlithic-flakes were base for making the tools., Eugeniusz Foltyn ... [et al.]., and Obsahuje seznam literatury
The paper presents the preliminary results of the analysis of two archival SAR datasets acquired by ERS-1/2 satellites of the same area of Roznow Lake in Southern Poland. Both datasets cover the same period of 8 years (1992 - 2000) and refers to the same area by the 50% of overlap between the neighbouring satellite tracks. The main purpose of this analysis was to derive the overlapping data about deformation velocity calculated using PSI (Persistent Scatterers Interferometry). The presented PSI results refer to PS (Persistent Scatterers) located on active landslides and therefore representing landslide movement. In Polish Carpathians, due to sparse urbanization, vegetation and rough relief the obtained PS density is usually not very high and generally difficult to interpret. The application of two overlapping datasets, where both of them observe the same phenomena, allow to cross-validate the data by identification of common PS points. For two datasets acquired from different tracks, usually many PS are not common and occur at different locations. Such situation could be explained by the difference between the incidence angles for both acquisitions. In a case of two tracks and therefore different terrain objects might act as PS. By joining the PS point sets from such neighbouring tracks the density of PS could be significantly increased. In order to perform a PSI analysis of Roznow Lake the data acquired from 179 and 408 tracks have been used and a few hundred of PS were obtained from PSI processing. For both tracks similar deformations velocity were obtained within a range of +/- 6 mm/yr. The PS points on active landslides are usually related to the buildings (walls, roofs) and roads affected usually by high risk., Zbigniew Perski, Andrzej Borkowski, Tomasz Wojciechowski and Antoni Wójcik., and Obsahuje bibliografii
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
