Waterfalls in Digital Topographic Databases and Digital Cartography
Pánová, Pavla ; Lysák, Jakub (advisor) ; Skalický, Filip (referee)
Waterfalls in Digital Topographic Databases and Digital Cartography Abstract The purpose of this work is to apprise a user with basic types of waterfalls and opportunities to improve information about them, especially to improve the ZABAGED database and a representation of The base map 1 : 10 000. The sectional purpose is to describe the waterfalls worldwide and their representation in foreign databases and maps, and a possibility to apply these findings for the Czech Republic. There will be presented a draft for automated creation of a cartographic presentation of the waterfalls and rapids for medium scale topographic maps, especially for The base map 1 : 10 000. There will be demonstrations of representation of the waterfalls from foreign and Czech sources as a supplement. Keywords: waterfalls, rapids, digital topographic database, digital cartography

Historical Topographic Database of Luční bouda and Surroundings Based on Early Maps and Ortohphotos
Chytilová, Barbora ; Lysák, Jakub (advisor) ; Suchá, Renáta (referee)
HISTORICAL TOPOGRAPHIC DATABASE OF LUČNÍ BOUDA AND SURROUDINGS BASED ON EARLY MAPS AND ORTOHPHOTOS Abstract The bachelor thesis aims to creating the digital topographic database of the Luční Bouda region in Krkonoše capturing its development in time. The database contains early maps and orthophotos data taken within the area. Among crucial archival spatial data covered, in the database we can count maps of Stabilní katastr, III. military mapping, aerial snapshots from 1936, Map of the Czechoslovakia from 1937, Map of State in scale 1 : 5 000 as well as orthophotos taken in year 1953 and later on. The theoretical part of the thesis includes introducing the area of interest, hictorical cartography, actual data and theoretical information involving digital topographic database creation with time constituant. The research deals with project itself followed by procedure of filling the database with data. The conclusion involves brief discussion on the development of the area in time. Key words Luční bouda, Krkonoše, digital topographic database, early maps, orthophotos

Utilization of ALS data for update of a road network
Kutišová, Tereza ; Lysák, Jakub (advisor) ; Brůha, Lukáš (referee)
Utilization of ALS data for update of a road network Abstract My thesis concerned problematics of automatic detection of communication data from aerial laser scanning. Goal of this method is to identify area of roads - tarmacs as accurate as possible. On its basis are counted attributes of specific parts. In first part of the thesis are summarized known procedures, which are used to deal with the issue and experiences and evaluation of the output of theirs authors. In practical part of the thesis is described procedure methodology, which is based on findings from the literature review. Subsequently, input data and model areas are introduced. In the final parts are described results and compared with the results of authors, who used such evaluation in their work. Key words: airborne laser scanning, digital topographic database, road network, database update

Generalization of Road Network in Topographic Maps
Vojtíšková, Zuzana ; Lysák, Jakub (advisor) ; Jindrák, Přemysl (referee)
Generalization of Road Network in Topographic Map Abstract The diploma thesis presents automated selection of the elements of path network. The review deals with this term and describes its position in map generalization process; the ways of path thinning apllied in the main Czech cartography institutions are reviewed too. Next part of the thesis describes the data and the tools that are applied in the proposed method. The main part introduces the suggested method of selecting elements of path network which was implemented on the test data. Keywords: map generalization, path network, path thinning, graph theory, ZABAGED, ArcGIS, Python, NetworkX

Topographic mapping of rock formations with the use of airborne laser scanning data
Lysák, Jakub ; Potůčková, Markéta (advisor) ; Brázdil, Karel (referee) ; Šíma, Jiří (referee)
Abstract This thesis focuses on topographic mapping of rock formations with the use of new technologies in a comprehensive manner, from airborne laser scanning (ALS) data acquisition and processing in rocky terrains, followed by their processing to the content of topographic databases and their cartographic processing in maps. The introduction discusses issues of importance for practice, and the relation between topographic mapping of rocks and other fields of human activity. The ALS section describes products for topographic mapping of rocks derived from ALS data, and discusses the specifics of ALS data acquisition and processing in wooded rugged terrain. Existing solutions of this problem are explained and their limitations are identified. Author's own approaches to solving this task are presented as case studies, including three made a further three designed experiments with ALS data processing and evaluation of their results. Recommendation regarding mapping of sandstone landscapes in Czechia have been also addressed. The topographic section describes the current representation of rocks and related objects in the ZABAGED database (Czech national digital topographic database), explains the historical context, analyzes this data and identifies their shortcomings in relation to the ALS.

Karst Phenomena in Digital Topographic Databases and Digital Cartography
Štysová, Lucie ; Lysák, Jakub (advisor) ; Šára, Pavel (referee)
The goal of this bachelor thesis is to provide a complex overview of the selected karst phenomena from the perspective of topographer and cartographer. The first part is devoted to introduction of karst phenomena from the viewpoint of geomorphology a hydrology, their characteristics and features, which play a key role in topographic mapping and with an emphasis put on the specific conditions of Czech Republic. Second part of this thesis is aimed on karst phenomena in the ZABAGED digital topography database and their representation in topographic maps. Also the Geonames database is introduces. Followed by an in-depth search of karst phemomena representation in foreign digital topographical databases nad their representation in large and medium scale topographic maps. The practical part is devoted to designing a representation of selected phenomena for ZABAGED and Geomanes including recommendation regarding its issues with emphasis on the use of the current JESO database and demonstrative filling of designed layers with real data. Also a cartographic representation of selected karst phenomena for large and medium scale topographic maps was designed.
