Land cover changes in military areas of Czechia
Outrata, David ; Štych, Přemysl (advisor) ; Červená, Lucie (referee)
1 Land cover changes in military areas of Czechia The aim of this bachelor thesis was to analyze and compare land cover changes in two areas affected by military activities, in military area Brdy and former military area Ralsko between 1986, 1998 and 2011. Maximum Likelihood supervised classification algorithm and Landsat 5 satellite images was used. Within the work was also examined the usability of Landsat images CDR, with atmospheric corrections applied. Reference data to gain control data were RGB and monochromatic aerial images. The classification system contained eight classes adapted to explored territory. Satellite photographs was classified on surveyed territories for the years 1986, 1998 and 2011, with overall classification accuracy ranged from 80.45% to 90.02%.With these data was further worked, and tables and graphs showing the area of individual land cover in the given time horizons was compiled. Outputs are also land cover maps, change maps and stable land cover maps. The expected trend that in the former military area after leaving the army land cover changed significantly, contrary to the current military area, where changes are minor, was confirmed. Key words: land cover changes, supervised classification, Landsat, Landsat CDR, military areas, Brdy, Ralsko, Geomatica, ArcGIS

Creation of water habitats database on spoil banks in Mostecko region
Macková, Klára ; Solský, Milič (advisor) ; Gdulová, Kateřina (referee)
Post-mining sites may pose a suitable environment for many rare and endagered species, amphibians are not an exception. Population size of the model species named agile frog (Rana dalmatina) has been observed already for eight years on more than 900 water surfaces of four heaps in the Most region. The observation is based on counting nests in the spring season. Annually are the results of the counting recorded together with charasteristics of observed water surfaces. Especially noted are their expance, deepness, slope of the shores, pH, conductivity, share of aquatic vegetation etc, as well as fotodocumetations and GPS locations. In similar studies where greater number of sites is repeatedly visited, there could be a problem with the reliability of tracing exact places. For the orientation in space is usually used orthophoto map and GPS navigation with dot layer of individual sites. Errors can occur because of the large number of frequent locations, close situated locations, confusing terrain and their own error of GPS devices. There was thus to inaccuracies in the positioning of individual locations, which resulted in a poor record of each habitat. Appropriate procedure to refine the results of field research, was to create a database containing photos of the previous year and point attributes of the area and transfer to GPX format so that it can be displayed directly in the ground used by GPS devices. For this purpose was used ArcGIS geo-information system, Office software package from Microsoft and software Notepad ++. This work consists of three main parts: a literature review, methodology and attachments. As an attachment there is a detailed procedure how to uploads attributes and points photos to GPS device.

Division of Europe with the use of GIS
Burešová, Daniela ; Hudeček, Tomáš (advisor) ; Bláha, Jan Daniel (referee)
Division of Europe using GIS Abstract This work focuses on theoretical and practical division of Europe into parts using GIS. The main scope of this work is using the program ArcMap to define the region of Europe and then to divide it into parts. An important sources are background research of literature which found different types of dividing the continent, and the underlying data ESRI. Geographic distribution of map of Europe was made on the basis of identified types of division. The main criterion by which Europe is divided was the total area of the continent and individual countries. Just based on the area the correlation analysis showed the appropriateness or inappropriateness of labeling different parts of the continent, from the geographical point of view. The result of the work are maps outputs that shows the differences and similarities in each division and used terms. The newly created maps are confronted and compared with original maps. Keywords: Division of Europe, ArcGIS, Geographical median

Assessment of methods of accessibility analysis of sociogegraphical regions in Czechia
Navrátil, Jan ; Hudeček, Tomáš (advisor) ; Schneider, Michal (referee)
The aim of diploma thesis is to compare methods of accessibility analysis in regions. The result of the analysis must cover only the region itself and not to overlap the neighbouring regions. This condition must be valid for every single region in the multi region system. The first part of the thesis deals with the methods which make the analysis possible. There are described their main characteristics and their advantages and disadvantages. The core part of the thesis consists of the detailed description of the functions and the approaches in the models and scripts, which were based on the methods identified in the former part. The methods are evaluated by the broad use of the models and scripts with various data samples. For every method is found an applicable use. The results are basis for the further inquires and questions eventually leading to the better understanding and the enhancement of the current approaches in that matters.

Sustainable production capabilities of territory, depending on climatic drought.
Skůpová, Jana ; Uhrová,, Jana (referee) ; Dumbrovský, Miroslav (advisor)
In this work, I dealt with the repercussion of drought on agriculture and land in the cadastral Jinošov. For this area, I analyzed the erosion and ratio of outflow. I also conducted a proposal of adaptation measures against erosion and water retention in the area. In conclusion, I analyzed withholding data and assessed the retention before and after the proposal of adaptation measures. The result of my work is finding that rainfall is inadequate and largely come out of the growing season, that despite all the measures fail to create on the necessary retention for the correct functioning of the landscape. Therefore it is necessary to solve water supply from other areas where is sufficient supply of water.

Optimal digital terrain model for erosion analysis
Středová, Kamila ; Brychta, Jiří (advisor) ; Rejha, Vít (referee)
The thesis deals with the question of using available sources of elevation data for the evaluation of topographic factor in estimating the amount of water erosion in the area. Work compares the results with consideration to the origin of the data, the accuracy and resolution of the digital terrain model, which is interpolated from the source data. The calculation of topographic factor in ArcGIS will be confronted with the results of the Universal Soil Loss Equation (USLE). The frequency of compliance will tell us which data source and digital terrain model resolution is the most suitable for determining the topographic factor.

Location study of suitable sites for pumped storage power plants
Strnad, David ; Gdulová, Kateřina (advisor) ; Bašta, Petr (referee)
This theses reports on facts about pumped storage power plants. The first part
of the theses introduces us to the importace of hydropower, consists of a description
of historical development of pumping sets, and also defines limitations for its
potential suitable localization.
The research is processed via ArcGIS software and it´s methodologically divided
into three phases. The first phase is searching for the minimum suitable terrain
gradient on the whole Czech landscape and it defines local insterests for the next
phase of research. The second phase is based on limited factors and assesses the
chosen location of interest. The final phase provides detail on the most potentially
suitable destinations with specific locations of pumped storage power plants.
The study resulted in map outputs of final destinations and locations of interest
across the Czech landscape.
The distinction of source data and the importace of classification of enviromental
factors are included in the discussion.
