Analýza vlivu kvality digitálního modelu terénu na odtokové charakteristiky pomocí modelování v GIS
 LORENCOVÁ, Iva
This diploma thesis focuses on the analysis of the influence of the quality of the digital terrain model on the runoff characteristics in the Bedrč, Oldřichovec and Rájov river basins. The objective of this thesis is to create different digital models. Based on them, the surface runoff volumes are calculated. The resulting runoff volumes are compared with each other. The difference of runoff lines in space depending on the created DMT is also compared. The theoretical part of the thesis contains a literature search which focuses on the description of runoff, geographic information systems, creation of digital models and CN curve theory. The practical part of the thesis is focused on the description of the creation of digital models, calculation of surface runoff volume and calculation of culminating flow. The methodology contains a detailed description of the data processing for the creation of the 1st generation digital surface model, the 4th and 5th generation digital elevation model and the digital terrain model from contours. In addition, the practical part describes the process of calculating surface runoff volume and culminating flow. Then the results are evaluated.

GIS analýza viditelnosti významného bodu v krajině a její ověření v terénu
 LORENCOVÁ, Iva
This bachelor thesis focuses on the analysis of the visibility of the Hluboká nad Vltavou state chataus, using ArcGIS software. The aim of this work was to crate a visibility analysis for two differenc digital models and compare them. The theoretical part of the thesis contains a literature search that describes geographic information sys-tems, the creation of digital models and visibility. The practical part of the work is focused on the description of obtaining data for the work and also contains a more detailed description of the area of interest for which the visibility analysis was pro-cessed. The methodology contains a detailed description of data processing for the cration of a digital model of the surface of the 1. generation and digital model of the relief of the 5. generation. Furthermore, the practical part of the work describes a detailed procedure for creating a visibility analysis. Subsequently, the results are evaluated and verified in the field
