Influence of landscape type surrounding the roads towards the frequency of traffic accidents in Písek region
Necid, Pavel ; Bašta, Petr (advisor) ; Gdulová, Kateřina (referee)
Bachelor thesis aimed on analysis of car Accidents in the area of MEC Pisek in relation to the landscape. Database of car accidents within years 2007 - 2013 was analyzed as well as the basic terrain parameters.The results show high complexity and interconnection between all factors. The results of simple database analysis show, that there is higher risk of car accident on Monday and Sunday, as well as highest risk of drink drive offence on Saturday. Elevation and slope of the terrain does not play any major role. There is also no reason for fear from driving in the forest. For detailed analysis, much more complex data are needed.

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.

Analysis of the water network development and utilization of water resources in and around Hradec Králové
Barborik, Lukáš ; Gdulová, Kateřina (advisor) ; Bašta, Petr (referee)
This thesis analyzes the use of water resources, development of water supply and water management structures since the 60s of the 20th century to the present day. Background materials provided on request by Vodovody a kanalizace Hradec Králové a.s. from their archives.
The materials consist of text and map outputs from master plans of water supply network. For the analysis were created maps of water network in the years 1973, 1981, 1994 and 2010, whose underlying maps are digitized material from the period. As graphical output was used ArcMap program.
The analysis assesses the development and future of drinking water resources, water network and water management structures and can serve as a starting point for a more detailed examination of historical events and developments in and around Hradec Králové.

The comparison of digital terrain model sources in GIS for hydrological purposes
Klempíř, Hynek ; Bašta, Petr (advisor) ; Gdulová, Kateřina (referee)
This thesis deals with comparsion of digital terrain models from different
sources processed in GIS for hydrological purposes. The diploma thesis is
composed from several parts. First part sis consist of characteristics related to
watershed and water flow, which are important for the understanding this work. The
thesis also describes digitial terrain model, his creation and methods for obtainig
digitial models. Then, there are described data sources from which is possible to
gain digitial models. Next chapter is dedicated to the coordinate system. The last
parts of this thesis describes drain alghorithms.
Characteristic of this area was collected on experimental watershed Modrava II
with the ESRI ArcGIS Desktop software that would mainly Spatial Analyst and
ArcHydro extensions.
The results of this diploma thesis can be concluded that the free digital terrain
model SRTM 90 is not suitable for small regions with diverse terrain structure. Thereason is a small resolution model. Other terrain models provided free of chargé are
sufficient even for small areas as the selected area of interest. Paid digitial models
can al lbe established for the area of interest as appropriate.

The impact of environmental factors on traffic accidents - case study from Liberec Region
Lang, Jan ; Gdulová, Kateřina (advisor) ; Klápště, Petr (referee)
The thesis is based on theoretical foundations and data from the traffics accident
rate. The data was processed by Geographical Information System (GIS) which
evaluates the influence of the environment on the amount of the traffic accidents rate
on a case study of the Liberec region.
Theoretical part include the issue of traffic accidents in the czech legislation, specific
traffic accidents, the theory of environmental influences on traffic accidents and
assesses the importance of statistics with regard to traffic accidents, which forms the
foundation for practical work.
Practical part performed in the program ArcGIS deals with the determination of
accident sites and sections in the district. Within the multi-criteria analysis
determines the relationship of traffic accidents with the environment and thus
identifies potential sites of traffic accidents.

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.
