GIS application methods in antropology
Bashir, Faraz Ahmed ; Štefanová, Eva (advisor) ; Potůčková, Markéta (referee)
This bachelor thesis aims to use of geoinformatic methods in anthropology. Specifically methods of terrestrial laser scanning and close range photogrammetry. The theoretical part focuses on explaining functioning and usage of those methods. Practical part of this work discribes data collecting proces with those methods and following creation of 3D model of anthroplogical artifact, specifically human skull. In the end those models are compared with model from computed tomography which was provided, same as anthropological artifact, by Department of anthropology and human gentetics of Charles University.

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.

Utilization of optical and laser data for modeling forest areas
Jebavá, Lucie ; Potůčková, Markéta (advisor) ; Dušánek, Petr (referee)
The thesis deals with the possible use of optical data for modeling forest area compared with utilization of airborne laser scanning data. At first these two datasets are compared and causes of differences are explained. Then canopy height models are made and object-oriented classification is applied for separation of vegetation stands. Methodical procedure is suggested for delineation and detection individual trees in forest. Then their height is detected. There are summarized and other possibilities for improvement in detection and delineation of trees. The results show that optical data with resolution about 25 cm are suitable for dermining the characteristics of the forest stands up to individual tree level. The outputs of this research can be used for forest inventory. Key words: aerial imagery, image matching, laser scanning, point cloud, forest inventory

SBU_1702
Hanuš, Jan
The purpose of aerial hyperspectral campaign with laser scanning of surface over the Dehtare area (Českomoravská vysočina highlands) was to obtain data for the study of water vegetation stress in the agricultural landscape. The data sets were scanned using the Flying Laboratory of Imaging Systems of the Global change research institute CAS in spectral range 380-2450nm, 8000-11500nm and LiDAR cloud density of 0.5 point per m2. Georeferenced and atmospherically corrected hyperspectral data was passed in spatial resolution 2 and 5m.

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

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...

Simplification the Digital Terrain Model based on TIN representation
Pancová, Iveta ; Bayer, Tomáš (advisor) ; Potůčková, Markéta (referee)
The Generalization of the Digital Terrain Model Based on the TIN Abstract This diploma thesis deals with the up to now way and the possibilities of the digital terrain model generalization based on the TIN (the triangulate irregular network). New suitable way of the generalization of the digital terrain model procured from laser scanning data is proposed on the base of the existing generalization methods designated for digital models. Laser scanning data is characterized by a high areal density so the basic requirement is computing speed, maintaining the terrain features, such as a ridge, valley, steep hill, saddle, depression … and so on. The proposed algorithm is compared with the results of suggested algorithms and results from the generalization by the geographic software, such as Atlas DMT and ArcGIS.
