Airborne laser scanning has already become an essential part of forest inventories in the Nordic countries and in Canada. However, its wider practical forestry application in the Central European countries is awaiting. In the first part of this thesis, a procedure for modelling of the basic stand variables, especially forest stand volume, was designed using an area-based approach. Not only linear regression was used for modelling but also machine learning (k-nearest neighbor algorithm, Random Forest, Support Vector Machine and neural networks). In the second part, the thesis deals with biomass estimation using the area-based approach and with comparison of the empirical and semi-empirical approaches to modelling. The third part deals with leaf area index (LAI) estimation using penetration indices and LiDAR metrics. The eLAI estimated by optical method is commonly used for model fitting in overwhelming majority of scientific papers. The benefit of this study is usage of LAI derived by destruction method (directly). The thesis as a whole has shown that the airborne laser scanning is also usable in a variety of forestry applications in Central European countries.

Air accidents related to both airplanes and airliners are often at the centre of heightened media attention. Whereas commercial media often choose to include in their news service only those accidents that result in number of fatalities or in a significant property damage, public service broadcasters should not take into account these criteria on order to provide balanced and versatile news service promoting an independent formation of opinions. In the case of news agencies, whose general mission is to collect and provide information, this assumption is doubly true. This thesis aims to analyse textual news products of the Czech News Agency using the example of the Agency's news coverage of air accident which happened in 2011 in the Czech Republic. This analysis will be used to determine the information quality on The first part of this thesis offers a theoretical basis for analysis - it describes the circumstances of the selection of news and related critical thinking approaches. The second part involves the actual qualitative content analysis of the news, mainly through comparison of media production with institutionally processed data depicting the real state of aviation accidents in the analysed period.

Theoretical part of this thesis presents the Project GeNeSiS and New Elevation Model Project of the Czech Republic Territory, in which the test datasets were acquired. Simultaneously this section describes in detail methods of co-registrations datasets from strip adjustment to 3D least squares matching method, which have been published until now. In practical part of the work the Pravčická brána model region is introduced firstly. The focus of this section lays on description of new methodology for co-registration and classification of point clouds using spatial query. Co-registration of point clouds, respective detection transform parameters in this thesis is solved by introducing ground control areas. For each such region displacement and rotations in each axis are detected which subsequently determines the global transformation key. Innovation of the thesis lies in the fact that for DTM improvement there is sufficient only one point cloud. The second (and possibly others) point cloud is classified by presented algorithm...

Assessment of forest damage using satellite and lidar data Abstract The main objective of this thesis is to create a methodical procedure used for the evaluation of forest damage in the chosen area of the National Park Sumava, Czech Republic. In this work were combined the multispectral satellite data and data of airborne laser scanning. The forests in this area are heavily damaged mainly due to bark beetle outbreak. You can find here as healthy so damaged forests. Based on this methodology will be differentiated greater number of classes than I found in the literature. In this work was used pansharpened multispectral image SPOT, multispectral image Landsat and airborne laser scanning data with low density points. Another task was to get height information from ALS data in the form of grid. Forest stands were classified using object-oriented classification, which included at first segmentation and then creation of classification base. In classification entered spectral information and height information obtained from the ALS data. Forests were classified into 5 classes and accuracy of both classifications was evaluated using the error matrix and kappa coefficient. SPOT image classification reached kappa coefficient of 68,5 % and Landsat image classification reached kappa coefficient of 72,3 %. From the...

76 Abstract Topical issues of the regulation of international air carriage The object of this presented thesis is to inform readers about the phenomenon of the international air carriage. This rapidly growing transport industry is bringing attention mainly because of its thorough practical usability. The first part of the thesis is dedicated to the specification of the basic concepts, these will be found in the rest of the thesis all through. To comprehend the actual topical issues it is essential for the reader to familiarize with the historical development of the air carriage. Especially in the 20th century the air carriage went through a swift progress that lead to a recent modern aerial transportation for long distances as we know these days. The second part draws attention into the basic legal sources of the air carriage concentrating not only on the international and European level but also on the Czech laws. Transport customs are not omitted, neither is practice of the courts that has a growing importance. Author of this paper engages in particular rights of the passengers in the air transportation and subsequent liability of the carrier in the third part of the thesis. Recently travelling through the air has become a very commonly used method of transport. From this reason it is necessary to point...

The subject of this bachelor's thesis was to create, from a point cloud, a suitable digital surface model for analysis of vegetation gaps of natural spruce-fir-beech forest. The input data were obtained by means of 2010 airborne laser scanning and 2004 airborne photogrammetry in the territory of Žofín primaeval forest. To create the digital models, several interpolating methods were utilized by means of the AcrMap 10.2 software using the free LAStools toolbox. Subsequently, cuts were created from these models. The cuts were compared in the Pointools View 1.7 software and their capability to truly copy the canopy surface and suitability to search for vegetation gaps were evaluated.

Leaf area index (LAI) is the most important variable influencing the penetration of solar radiation beams through the forest stand. Currently, the airborne laser scanning, as new indirect method, suggests itself for estimation of LAI. LAI was measured terrestrially using the hemispherical photographies analysis and compared with LiDAR Penetration Index - LPI. There were created several regression models describing the dependence of LAI and LPI with coefficients of determination from 0.71 up to 0.81. Leaf area index was also applied to the Beer-Lambert law for calculation of the solar radiation in forest stands. Practical application possibilities of LPI in forestry (estimation of stocking, optimization of shelterwood cuttings etc.) have been described in conclusion of this diploma thesis.
