Wilhelm, Adam
This bachelor’s degree thesis is focused on reconstruction of defunct medieval trade road between the castles of Litice and Potštejn in Eastern Bohemia. Spatial vector and raster data were used for elaboration on this project. Recognoscation of the current terrain was taken in account. For the data collection, ArcGIS Pro and Atlas DMT softwares were used. For purpose of reconstruction of the road, research themed on the history of the roads and road network focused on big commercial arteries and important roads passing through our territories was processed. Historical survey of the local territory of the Litice Manor was carried out and characterization of the cadastral areas was processed. On this basis the project of the reconstruction of the merchant road was established.

Monitoring rozšiřování plantáží palmy olejné v Nikaragui pomocí metod dálkového průzkumu Země
Mezihoráková, Tereza
The first part of this bachelor's thesis is literature research that discusses the expansion of oil palm plantations in Central America, as well as remote sensing and monitoring of forest and agricultural areas using its methods. The practical part deals with the monitoring of oil palm plantations between 2017 and 2022 using satellite data. The analysed area was the Kukra Hill region located in the state of Nicaragua. PlanetScope multispectral images were used for the analysis. First, vegetation indices were calculated, classifications were made, the areas of plantations in the given years were determined and their comparison was made. In 2017, the area of oil palm plantations within the area of interest was 4,109 ha, but of this area, 445 ha disappeared by 2022, so 3,664 ha were preserved from 2017 to 2022. In 2022, the area of plantations was already 8,512 ha, which means that the area of oil palm plantations increased by 4,848 ha between the given years. The used methodology can also be used in other areas with similar geographical conditions, where oil palm plantations are expanding and will contribute to better monitoring of the studied phenomenon.

Soil erosion risk analysis in Sidama Region, southern Ethiopia
Bizunhe, Getie Balkie ; Martínek, Karel (advisor) ; Hroch, Tomáš (referee)
Soil erosion is one of the most important environmental issues in Ethiopia. Studies on erosional processes and soil loss rates can provide insight into the landscape evolution, climate change, and human activities, as well as on land degradation risk. The soil coverage of the Sidama Region study area, Main Ethiopian Rift, is characterized by Major Reference Soil Groups as follows: Luvisols, Cambisols, Nitisols, Vertisols, Andosols, Fluvisols, Regosols, and Leptosols. Cambisols and Luvisols are more susceptible to erosion. Revised Universal Soil Loss Equation (RUSLE) is most developed and recently widely used algorithm which was used to map and estimate the spatial distribution of soil erosion rates in the study area. Two rainfall datasets and three soil structure datasets were tested for reliability. The resulting 6 RUSLE calculations were validated by field mapped polygons in selected areas. It showed that most reliable input datasets are new more complete rainfall data and soil structure data derived from field mapping and sample analysis. The most susceptible areas of soil loss are mapped and the mean soil loss rate in the study area is 28 t/ha/yr. The mean annual soil loss of Sidama study area is above the tolerable mean soil loss (18 t/ha/yr for Ethiopian highlands). The Revised Universal Soil Loss...
Utilising satellite imagery for geological mapping and structural analysis
Sokolová, Anna ; Lexa, Ondrej (advisor) ; Martínek, Karel (referee)
The use of remote sensing data is becoming very important in Earth sciences. Satellite images are invaluable for studying hardly reachable places on Earth and they can significantly help increase the efficiency of work in areas with existing field data . In arid areas where rocks are exposed and directly visible at the surface, a lithology contacts mapping can be done based on satellite images. An overview of the possibilities of processing multispectral images is included in the theoretical part of this thesis, as well as a description of previously known methods for performing structural analysis based on remote sensing data. As the main part of this thesis, a new method for finding orientations of planar geological structures including a quality control of the input data was developed and described. This method was then applied in the Bodonchin area of the Mongolian Altai where the metamorphic foliation and pegmatite veins were analyzed. The method showed good applicability in the given area despite its limitations which are also discussed in the thesis.

ALS application in the landscape protection of protected heritage zone in Kremnica
Miňo,Martin ; Dědič, Peter ; Flórová, Mária ; Lieskovský, Tibor
Kremnica was an important mining town in the kingdom. Because of the gold mining it has become since the Middle Ages the seat of the royal mint, which works until today. The mint is the last of the working components with the exception of minor mining in the Andrej shaft upon which the economy and the importance of the town were built. The remnants of the mining activities went through the process of natural succession and blended into the wooded landscape. Despite the area is a protected heritage zone since 1999 its valuable landscape components were not sufficiently known and protected because of broken topography and natural succession. It became visible among others in the way the border of the heritage zone was established. In several places it leaves valuable relicts without protection. Slovakia's landscape is gradually airborne laser scanned (ALS). The source data allow to create a digital surface model (DMP) in very high resolution, which is 4 times higher than most of the commonly available data. DMP is visualized by a specialized workflow highlighting relics of cultural heritage. Full-area ALS of Slovak landscape came just when the regulations of the protected heritage zone needed to be updated. This facilitated the configuration of a new assessment approach for this site using a combination of LLS interpretation, historical maps and field surveys. For presentation and practical use of state administration a practical GIS model was created and an interactive 3D model of the area is being prepared as an important tool mainly for consideration of new building inputs in the protected zone.
