 Hlaváčová, Iva ; Štych, Přemysl (advisor) ; Suchá, Renáta (referee)
Thesis is about European map of built-up areas with high resolution and the term about imperviousness (Soil Sealing Layer). The main aim of this bachelor thesis is to evaluate thematic accuracy of the Soil Sealing database in the Czech Republic with use of various statistical methods. The theoretical part deals with problems of impervious surfaces, outlines the framework of database development with principles of its creation. It is also about accuracy assessment of spacial data with specific examples. Validation is based on comparison of assessed grid with visually interpreted orthophotos. The comparison will take place within the targeted selection of three locations. Statistical methods will be applied on obtained data for particular areas and clarify accuracy of database depending on compactness of settlements. According to the results of validation, single methods and outcomes will be critically evaluated. Achieved results will be compared with similarly oriented studies. Powered by TCPDF (www.tcpdf.org)

 Pohlová, Radka ; Štych, Přemysl (advisor) ; Chuman, Tomáš (referee)
The aim of this work is to give information about the European built-up area map with the high resolution which also contains the data concerning the soil sealing (Soil Sealing Layer). The main aim of this bachelor thesis is to evaluate thematic accuracy of the Soil Sealing database in the Czech Republic with the usage of the statistical methods and decision of its acceptance or rejection. This work also assesses its suitability and the next usage. At the beginning of the thesis there is a research relating to the issue of the built-up areas and statistical methods evaluating the database accuracy. There are explained the basic principles concerning the creation of SSL database and its validation which is made by the comparison of the validated database and the visually interpreted ortophotos. The evaluation of the database will be carried out by the unstratified random sample. Primarily, the statistical methods will be applied on the whole database and afterward they will compare the Czech areas divided according to the year of scanning of ortophotos from which the reference database was created. Besides the validation itself there will be a comparison of the quantitative methods followed by the evaluation of their advantages and disadvantages. Powered by TCPDF (www.tcpdf.org)
