    Opis:
    Various structural observations were collected in southwestern Podhale Trough during investigations for Detailed map of Tatra Mts., scale 1 : 10 000. Fault surfaces, strikes and dips of beds and fold axes were measured in the field. Statistical analysis of results allow to recognize 5 groups of dislocations with variable types of movement, directions and age: 1) slickensides onW-E striking, almost horizontal bedding surfaces show reverse motion towards S, 2) steeply-dipping (80–90(centigrade)) faults, striking parallel to bedding and also showing reverse motion towards S, 3) vertical transcurrent faults associated with main tectonic zones, striking almost N-S, 4) normal faults striking ca 38(centigrade) (NE-SW) and 135(centigrade) (NW-SE). Attitudes of beds different from regional trend were separated. Deviations are caused by flexural bending along tectonic zones. Anomalous attitudes of beds coincide with directions of dislocations recognized in the field. A map of lineaments in the study area is also presented. Analysis of landforms on Digital Terrain Model (DTM) led to recognition of series of lineaments related to either tectonic structures or lithology. Main transverse tectonic zones were identified on the map of lineaments: Chochołowski Potok-Czarny Dunajec, Kooecieliski Potok, Mała Łąka; as well as some minor faults and zones where particular directions of faults predominate. Statistic analysis of directions of tectolineaments allows to recognize 4 main directions: 1) about 90°, associated to thrusts and folds (parallel to strikes of beds), 2) N-S and slightly oblique directions associated to transcurrent zones, 3) approximately 40(centigrade) and 4) 140(centigrade) directions associated to normal faults. Results obtained using these 3 methods (analysis of field data, analysis of DTM, analysis of attitudes of beds different from regional trend) are consistent with each other.

    Opis:
    This article presents the results of digital terrain model analysis and field observations related to occurrence of characteristic forms in landslide surface that may indicate the geological setting. Based on these observations, three characteristic structures were selected occurring on many landslides in the Carpathian Mountains and the Carpathian Foredeep. The former are the wrinkle structures visible on the digital terrain model associated with movement along the bedded surface. The other are the streak structures linked to the occurrence of gravels and sands on the clays. The third mogul type structures are related to cylindrical sliding surfaces formed in clay.

    Opis:
    The study is focused on an active landslide located on the right bank of the Dunajec Valley in Zbyszyce. The potentials of application of the data derived from airborne laser scanning (ALS) in the context of an inventory of landslides has been presented. The ALS data used in this study covers the area of 40 km2 on the eastern side of Lake Roznowskie in the Carpathians. Scanning data were acquired on April 1, 2010, and the resulting cloud of points was used as the basis to generate the DTM with a resolution of 0,5 m. Geological interpretation of the data was conducted on the example of the largest and complex landslides in the study area located in the village Zbyszyce. Using different visualization techniques were able to determine extent of landslides and its internal morphological elements. Attempts to determine the degree of activity in different zones of the landslide have been also undertaken. Very good results were obtained in wooded areas, complementing the state of knowledge about this landslide.

    Opis:
    The use of multi-temporal LIDAR data in the study of landslides gives many possibilities. The increasing-over-time availability of ALS data encouraged research on development of landslides using Differential Digital Terrain Models. An important passive factor that determines the development of landslides (especially in the Carpathians) is lithology. The author propose a new lithological displacement index, that dscribes the volume of displaced ground (m3 ) per area of 1 m2 of a given lithological unit. The example of the test area of Rożnowskie Lake has shown that lithological displacement index can assess the landslide susceptibility, which is variable and depends on the amount of rainfall. During periods of heavy rainfall, large volumes of displaced rock masses were recorded in the thick-bedded formations. In dry periods, the trend is reversed.

    Opis:
    The article compares results of field assessment of activity of selected landslides in the Rożnowskie Lake region, obtained in 2010-2014 with a differential digital models (DDM) from airborne laser scanning data of 2010, 2013 and 2018. Results of DDM analyses were similar to those from field studies. The most difficult task in the field research was to distinguish between active landslides, where the last movements took place over three years after the date of landslide registration, and periodically active landslides, the last visible movements that took place five years ago. The article underlines that not all displacements within the landslides, visible on differential terrain models, are the result of colluvium landslide movement. Sometimes they are due to anthropogenic activities. Differential digital model in the Znamirowice landslide presents terrain changes that have resulted from intensive agricultural land use.

    Opis:
    In the northern part of the Great Mazurian Lakes there is a post-lacustrine plain extending over 90 km 2 . This depression, called Skaliska Basin (Kondracki, 1998), is situated NE of Węgorzewo, overlapping the state boundary between Poland and Russian Kaliningrd Region (thus the northernmost part of the structure was not accessible for study). A glaciolacustrine lake existed there during Late Pleistocene (Pochocka-Szwarc & Lisicki 2001a, 2003). Defining the exact extent and direction of outflow from the Skaliska Lake are most important aims for palaeogeographic investigation of the area. For paleogeomorphological analyses of the Skaliska Basin, the following methods were used: Digital Terrain Model (1 : 200,000 scale), Landsat TM satellite images, archival cartographic materials, and results of geological investigations accompanying compilation of sheets Budry (Pochocka-Szwarc, Lisicki 2001a) and Banie Mazurskie (Pochocka-Szwarc 2003) of the Detailed Geological Map of Poland (1 : 50,000). The study allowed to recognize the lateral extension of the paleolake, and reconstruct the sequence of events that led to catastrophic out flow towards the NW.

    Opis:
    The paper presents the geological interpretation of Airborne Laser Scanning data of Kasprowy Wierch Mt. area. The analyzed points cloud data represent the ground surface after removal of the land cover (primarily vegetation) objects. The ALS data were characterized by very high density, presenting even minor terrain forms, very difficult to identify in forested and mountain dwarfpine areas as well. The resulting image of detailed geomorphology of the study area was compared with existing maps at scale of 1 : 10 000 and literature data. This allowed verifying the extent of geological units of basement rocks and shed new light on existing opinions on the genesis of glacial sediments. An extensive landslide has been identified on the eastern slopes of Sucha Czuba Mt. The landslide has not been reported in the literature so far. Application of laser scanning data was extremely useful and allowed making new observations that enrich the existing knowledge about the geology of this part of the Tatra Mts.

    Opis:
    Landslides are very common features in the Polish Outer Carpathians. In the classical cartography, landslides are recognized based on characteristic land relief: main and side scarps, toe, minor scarps, transverse ridges, recesses and cracks. Formerly, landslide mapping was carried out in the field, preceded by interpretation of topographic maps and aerial photographs. Nowadays, we use spatial data from airborne laser scanning (ALS). Spatial data reprocessing permits to achieve a high-resolution (pixel 1*1 m or more precise) digital terrain model (DTM). Exploration of land relief in search for landslides has become simpler and more accurate. DTM interpretation allows delimiting the boundaries of landslides and elements of their relief. By analysing groups oflandforms it is possible to determine the type of colluvium movement. In the eastern part of the Low Beskid Mts., four types of landslides predominate: rotational slides, translational slides, flows, and complex movements. Types of landslides are usually very well visible on the DTM. Information about types of mass movements can be useful during modelling further landslide activity and designing instrumental identification works and possibility ofstabilization.

The first part compares the method of obtaining products from UAV with airborne laser scanning, showing its limitations and advantages. Then, examples of using the products made from photos obtained from UA V raids (digital surface model - DSM, digital terrain model - DTM and orthophotomosaic) were introduced. The examples are assigned to the individual phases of engineering geology documentation (collecting available information about the site, designing research, performing research and presenting research results). The last part presents an analysis of the accuracy ofan exemplary model created from a UAV raid based on control points measured using the GNSS-RTN method. The result of the analysis was the confirmation ofthe possibility of obtaining information about the area from the DSM, DTM and orthophotomosaic with high accuracy comparable to classic land surveying methods.

    Opis:
    For about 600 years Middle Jurassic iron ores had been mined in the Częstochowa region. This process created many forms, among which mining and processing waste dumps are the best visible in this area. After the mining process had stopped, mass movements occured in the surface of the dumps. The paper presents specificity of landslides developed in dumps in the Częstochowa region, intensity of this phenomenon and landslides activity. Mass movements are present in each dump higher than 40m and broader than 300 m. The large stand highest dump slopes are all covered by a vast landslide zones, where rotational slides and complex slides dominates. Despite the fact that exploration of iron ores had ended about 40 years ago, a large number of dump landslides are still active or periodically active. Some of these signs of activity can be seen on Differential Digital Model (DDM).

    The paper discusses the problem of quick acquire height data for calculation of escarpment stability. In past the slope of profile was obtainedfrom classical land survey methods (like Total Station, GNSS, etc.), carto- metric measurement on maps or measurements based on a Digital Terrain Modelfrom aerial photography. Now we have a new method that is Airborne Laser Scanning (LiDAR-ALS). In 2011-2014 almost all country was measured in this method. The declared accuracy of height measurement on the durable surfaces is about 0.10-0.15 m. Author compared this method with classical method Global Navigation Satellite System - Real Time Network (GNSS-RTN) on two wooded and bushy areas. The comparison was based on the measurement characteristic points on the profiles and acquisition of height data from LiDAR-ALS data. Data in this method were obtained in two ways: from point cloud and from DTM createdfrom this point cloud. In the next step, height differences were calculated and these data were subjected to basic statistical calculations. The result of the study was a mean error of height data from LiDAR-ALS and conclusions about its usefulness in acquire height data for calculation of escarpment stability.
