Development of selected invasive species and meadow vegetation classification algorithm in the Krkonoše Mountains using hyperspectral data
Jelének, Jan ; Kupková, Lucie (advisor) ; Halabuk, Andrej (referee)
Development of selected invasive species and meadow vegetation classification algorithm in the Krkonoše Mountains using hyperspectral data Abstract The thesis deals with utilization of airbone APEX hyperspectral image data for selected invasive species and meadow vegetation classification in the study area of the Krkonoše Mountains National Park. The mian goal of the thesis was to develop of classification algorithm based on proposed vegetation indices. The approach was based on the utilization of in-situ LAI, fAPAR, chlorophyll content data and analysis of their relation with vegetation spectral properties. The work also deals with several problems regarding LAI - vegetation indices relationship, namely saturation of LAI and mutual correlation of LAI and chlorophyll content. Tha classification was focued on invasive species Rumex alpinus and Lupinus polyphyllus, meadow vegetation with dominant Nardus stricta and dominant Trisetum flavescens and cutted lawns. Besides the proposed approach, the presented work resulted in several classification maps of study area and in spectral libraries, containing ground level spectra of studied invasive species, meadow vegetation types and several other meadow species. Keywords: hyperspectral image data, APEX, LAI, fAPAR, vegetation indices, invasive species, meadow...

3D reconstruction of landscape in abandoned villages of borderlands and military zones
Jelének, Jan ; Štych, Přemysl (advisor) ; Oršulák, Tomáš (referee)
3D reconstruction of landscape: A case study of extinct municipalities in Czech borderlands and military areas Abstract This work deals with theoretical and practical possibilities to use GIS to create three-dimensional model of landscape changes. The object of the work was the creation and visualization of three-dimensional model of extinct municipalities Padrť in a military area Brdy and Košťálkov in the borderlands. The work used many available data sources, such as historical aerial photographs, historical photos, current orthophotos or historical maps. These data and specialized software were used to create digital models of the selected area, including three-dimensional models of buildings and vegetation, with emphasis on historical closeness. Work was focused on three selected periods of history: 40th of the 18th century, 30th to 50th of the 20th century and present. The work resulted in fly-by animations and perspective scenes, which are compared with historical photographs. Historical models are also confronted with each other by a dynamic fading in fly-by animations.
