This diploma thesis is focused on examination of effect topography on yield on the field. Theoretical research is given in literary overview and it is focused on sources of elevation data in conditions of the Czech Republic. Further there is given description of topographic attributes, which have influence on crop on the agricultural field.
Practical part of this thesis processed data about agricultural field in Vendolí near Svitavy in East Bohemia. One of aims of this thesis was to compare two sets of elevation data. First set of elevation data was provided by Czech office for surveying, mapping and cadastre, data came from airborne laser scanning. Second set of elevation data was measured by DGPS receiver placed on combine harvester during the harvest. Topographic attributes were derived from these two sets of elevation data with help of tools in software ArcGIS 10.2. In the further process topographic attributes were compared with yield of winter wheat from 2014 to assess relationship between topography and yield. In given data there was found dependence of yield on digital elevation model (higher amount of yield was found in higher elevations). Significant relationship between yield and other topographic attributes has not been proved.
