Large-scale mapping of the St. Kilian Island near Davle with emphasis on comparison with existing data
Kradijan Seider, Filip ; Lysák, Jakub (advisor) ; Šedová, Adéla (referee)
The bachelor thesis aims to topographically map the island of St. Kilian near Davle, with emphasis on usage of own data. Modern methods of spatial data collection (drone photogrammetry) and processing were used. The site is mapped mainly due to the former presence of important monastery and the significant changes of local landscape in the last century. The historical state of the island has already been modelled, but today's models only include the terrain of the island. The emphasis of the thesis is on mapping the remains of the Ostrovský klášter Monastery, creation of digital models of the terrain of the island and the adjacent Vltava river bottom and subsequent large-scale cartography. The work describes the history and current state of the site and existing older data. The methods used to acquire spatial data and the cartographic aspects essential for the site map are outlined. The practical part presents the data and their processing, completion utilizing a field survey, comparison with historical data and map production, using the ArcGIS platform. Limited use is made of scripting using the ArcPy library. Keywords: Ostrov sv. Kiliána (Davle), the Ostrovský klášter monastery, drone photogrammetry, sonar, spatial data comparison

Preprocessing of geographical data for 3D printing and vizualizations: Case study Ostrovský klášter
Dastychová, Vendula ; Laštovička, Josef (advisor) ; Brus, Jan (referee)
The thesis deals with contemporary methods of converting 3D geoinformation model into analog/printed form using various types of printers. The thesis documents an overview of current works and methods used. The benefit of the thesis is the overview of methods, software and available options for 3D printing. Based two types of printers the thesis demonstrates outputs quality. Also, the thesis introduces a general prescription for the process of processing the geoinformation data of a 3D model to print it. This process is applied in course of preparation cpecific model. In the empirical part, the thesis is applied on the concrete case study of the historical modeling of the Ostrov monastery. An integral part of the thesis is also a comparison of outputs of two selected printers - powder and string type. Keywords: 3D print, technologies, methods of 3D print, 3D model, GIS
