Updating of land use cadastral records using satellite data Sentinel-2
 Šaffová, Michaela ; Štych, Přemysl (advisor) ; Kupková, Lucie (referee)
Updating of land use cadastral records using satellite data Sentinel-2 Abstract The aim of the project is to propose a methodical procedure which will classify selected land use classes with an accuracy of more than 80 %. Constructed methodical procedure will have the task of detecting the discrepancy of land reported in the cadastral records with the real state in the landscape identified by satellite Sentinel-2 data classification. Classification of agricultural land classes (arable land, permanent grassland, orchard and vineyards) is solved in this project using multitemporal data Sentinel-2 using object classification methods. The first part of thesis focuses on the literary introduction to the topic of the theme. The second part is devoted to the process of creating a methodical procedure for object classification of land use classes, where parameters are defined by experimental activity and thresholds of the defined classification. The results of the work are compared and evaluated using the overall accuracy and error matrices of the classification using the developed algorithm. Keywords: cadastral records, multitemporal satellite imagery, object-base classification, Sentinel-2, agricultural land resources

EVALUATION OF AGRICULTURAL LAND LOSSES IN THE CZECH REPUBLIC AFTER 1990
 Šaffová, Michaela ; Štych, Přemysl (advisor) ; Holman, Lukáš (referee)
The work is focused to evalution of trends in the decline of agriculture land in the Czech Republic in the period 1990 - 2012 using data from CORINE Land Cover database. Assessment agriculture land decrease was done in terms of the total area of land occupation and in terms evalution of Agricultural land resources quality decrease on based on the soil protection classes available from VÚMOP SOWAC-GIS geoportal. Another objective was to find out whether Agricultural land resources losses are related to the physical geographic and socio-economic characteristics of the surveyed territories (districts). In the period 1990 - 2012 was seize 45,135.44 ha of agricultural land in Czech Republic which 38,324.42 ha of land could be assigned to the category of Agricultural land resources soil protection. It has been prove that the dynamics of agricultural land occupation are steadily increasing. In addition it was confirmed that the most valuable agricultural land from protection categories 1 and 2 was a lot occupation. The participation of these protection classes was 44.14 % over the whole monitored period. Most of the agricultural land was transformed into a rosy type of development (83.41 %). The biggest occupation of agricultural land was recorded in districts of large cities and their backgrounds...
