Využití dálkového průzkumu pro odhad výnosů zemědělských plodin
 Rosendorfská, Eva
Knowledge og the crop yield with sufficient lead time prior to harvest is crucial for the farm management or national agro-food policy. Spectral characteristics provided by satellite based remote sensing have both spatial and temporal resolution which allow crop yields from agricultural fields. The aim of this thesis was to test feasibility of developing crop yield. The study was focused on three major crops in the Czech Republic: spring barely, winter wheat and oilseed rape. The crop yield data were collected from 14 districts that represent regions with more intensive agricultural production and include a variety of climate, topographic and soil conditions. As a main data source for this thesis was series of digital images acquired by MODIS (Moderate Resolution Imaging Spectroradiometr) aboard Terra satellite from 2001-2014 period. Were analyzed two vegetation idices NDVI (Noramized Difference Vegetation Index) and EVI (Enhanced Vegetation Index) from the 16-days composite product with a spatial resolution of 250 m. In most cases, EVI showed higher correlations to the crop yied, which can be explained due to the negative saturation effect of NDVI.

Legislativní dopady aktualizace systému bonitovaných půdně ekologických jednotek
 Rosendorfská, Eva
The bachelor thesis describes the precise definition of code of valued soil-ecological units (BPEJ) and climatic conditions. The thesis is concentrated on the whole system BPEJ, their origins and history. In addition to, it is focused on the approaching of the update of BPEJ in our territory. It is also described what legislation is related to breeding in the Czech Republic, which is dedicated, especially, to the spatial planning, vulnerable areas (LFA), taxes and the exclusion of the land from the agricultural land fund. Moreover, I describe the utilization of these values in science and research, where I will detaily focus on the project ReSteEP, the erosion control and the utilization of BPEJ in Land Consolidation.
