Measuring of facade of historical object by geodetic methods
OBERREITER, Milan
This study is focused on the ways of measuring the facade of the historical building. This activity has become more frequent in recent years due to the documentation of the status of architecturally valuable objects or the design of the renovation and the determination of the financial budget. The documented house is the house U Bílé labutě at Přemysl Otakar II. Square in České Budějovice.

Possibily GIS methods for documentation of paleontological relics
Čelonk, Marek ; Štefanová, Eva (advisor) ; Potůčková, Markéta (referee)
Possibily GIS methods for documentation of paleontological relics Abstract The bachelor thesis is focused on use of geoinformatic methods for creation of 3D model. The thesis is produced in cooperation with the Chlupáč's Museum of Earth History, which lent a paleontological artifact for processing. The theoretical part deals with laser scanning and close-range photogrammetry. Both methods are used in the practical part for own data colection and subsequent creation of 3D model. Data processing was mostly done in Trimble RealWorks, MeshLab and Agisoft PhotoScan. Another output is the HTML page that allows visualization in the Internet environment. key words 3D model, laser scanning, close-range photogrammetry, point cloud

Vytvoření 3D modelu jeskyně Koňská jáma z dat pozemního laserového skenování pro potřeby CHKO Moravský kras
Gaja, Martin
The thesis discusses the use of relatively new technologies laser scanning for speleology surveying. The impulse for the creation of this work are simple, in many cases inaccurate surveyings the caves, which are, since inception for a long time, used up to now. The work describes the process of data acquisition by terrestrial laser scanning, then their processing and outputs that can be present or work with them. It is also evaluated the appropriateness of using this method in speleosurveying and compared with the currently used methods.

Local scale snow accumulation and ablation variability using high spatial resolution data
Cuřín, Vojtěch ; Jeníček, Michal (advisor) ; Minařík, Robert (referee)
The focus of this bachelor's thesis is snow depth variability at local scale and modern methods of snow depth measurement with high accuracy, precision and resolution. The main goal is to provide an overview of current research in this area, give comparison of the most widely used methods and outline their most appropriate fields of application. A part of this work is also dedicated to an evaluation of snow distribution over a study area in Filipohuťský creek basin in Šumava (Bohemian Forest) and to an assessment of the impact of selected variables on snow depth variability using multiple linear regression models. This is done using manual snow depth measurement data and local digital surface model with high resolution. Multiple linear regression models capture the snow depth variability more precisely than models based on ordinary kriging, nevertheless the regression coefficients of selected predictors are too inconsistent to confirm their effect. Key words: snow depth, photogrammetry, laser scanning, multiple linear regression

Classification of road network from airborne laser scanning data and from remote sensing images with high resolution
Kuchařová, Jana ; Potůčková, Markéta (advisor) ; Kupková, Lucie (referee)
Classification of road network from airborne laser scanning data and from remote sensing images with high resolution Abstract Object classification of land cover is currently one of the methods of remote Earth exploration. Road network classification only is unique because it is covered with anthropogenic material and has different characteristics than other elements of the landscape. This work deals with the possibility of using a combination of data from airborne laser scanning and high resolution optical data for detection of the road network in the specific area. The premise is that the use of two different types of data could provide better results, because airborne laser scanning data provide very precise information about the position and height of the point, while satellite data of very high resolution represent the real landscape. Searching for suitable features and classification rules for unambiguous determination of the road network is one of the objectives of the work. Segmentation parameters will also be important for object classification. Another objective is to verify the transferability of classification schemes into the other scene. The results should present a response on whether a procedure can be applied over a different location and also that the use of two types of data can bring...

Design of Pravčická brána 3D model and its integration with 2.5D TIN terrain model
Brýdl, Ivo ; Brůha, Lukáš (advisor) ; Lysák, Jakub (referee)
The main goal of this thesis is to design integrated model containing a three-dimensional representation of Pravčická brána rock arch and 2.5D TIN model of surrounding terrain. Point cloud from airborne lidar measurements has to be classified into ground and non-ground features. The ground points are the basis of the TIN terrain representation. Second part of this thesis is focused on methods for reconstructing 3D surface from given points set retrieved with ground-based lidar measurement. The thesis describes the process of meshing point cloud with Poisson surface reconstruction. Finally, these two models are oriented and translated to real coordinates in order to form integrated hybrid model covering part of České Švýcarsko National Park.

Creating a 3D model of the White Tower in Hradec Kralove from terrestrial laser scanning data
Lagner, Ondřej ; Čábelka, Miroslav (advisor) ; Štefanová, Eva (referee)
This work is focused on processing data of digital terrestrial laser scanning of The White tower in Hradec Králové city and solving the problems closely connected to this. Data was processed in different graphical softwares, which were specialy made for this kind of tasks. During the processing, the softwares were compared according to established criteria. The mos usefull pragram Geomagic Studio 2012 was chosen and 3D model of the tower was made in this. To assess the accuracy of the model, was it measured by yardstick, and model was also compared with buildings plan.

Flood-plain Analylis of the Karolinka Dam
Píšek, Petr ; Vizina, Štěpán (advisor) ; Vokoun, Martin (referee)
The thesis analyzes flood consequences caused by failure of a damaged barrier or a particular component of water impoundment Karolinka. In the first part of the thesis there is described the history of water impoundments construction, both in the world and in The Czech Republic. The failure rate is described, followed by description of damage caused by flood. Finally, the ways of software modeling of flood wave transition are described, whereas special attention is given to program HEC-RAS. The data preprocessing and preparation were realized by ArcGIS software while HEC-RAS program was used for modeling. The specification of the floodplain of dam failure was the outcome of the modeling. The two inputs of data were used for comparison of results -- altimetry grid 10x10 m ZABAGED and Digital Model of relief of CZ of 4th generation (DMR 4G) acquired by aerial Laser Scanning.

Key steps in standardization of aerial photography (remote sensing) usage for forenzic ekotechnique: forest and trees needs
Introvičová, Sabina
The description of key steps for remote sensing data usage as base data for forensic ecotechnique expert opinions is a topic of the article. In accordance with systematic methodology in forensic ecotechnique, all accessible information about an object of examination should be employed. It follows that remote sensing data usage for expert opinions working out in the field of Forensic ecotechnique: forest and trees is necessary. Remotely sensed data was divided into three categories: aerial photography, radar imaginary, and satellite data; all with basic characteristics. The main problem of the standardization of remotely sensed data usage is in its dynamic development which has an impact of conditions for obtaining the data from different subjects dealing with pictorial data processing.

Sládková, Veronika ; Černý, Martin (referee) ; Hanzl, Vlastimil (advisor)
The subject of thesis was creation of methodic for building information modeling methods specified. The buildings were surveyed at first or projects drawing were provided. Processing of survey data and building information modeling was done in software Revit 2014 with program extensions. Subsequently chosen methods of creation were described and they were compared with each other. The result can use for selection the most appropriate method on the basis function and targeted funds.
