Analysis of rock hachures drawn using ladder style representation
Ludačková, Markéta ; Lysák, Jakub (advisor) ; Tomková, Michaela (referee)
The thesis deals with the analysis of the drawing of rock hatches created in a ladder style representation on the Czech state map series (SMD), specifically on the last edition of the analogue ZM 10. Therefore, the purpose of this thesis is to, on the basis of many specific uses of this method in maps, determine the frequency of occurrence of variants of the ladder style drawing and its possible spatial context for the purpose of future automation of their digital creation usable, for example, in the new SMD. A total of 11 clusters representing different styles of rock drawing were classified using a cluster analysis based on the calculation of features representing the geometric characteristics of the drawing of the rock. This result represents an exact confirmation of the hypothesis presented in the scientific literature that the drawing of the rocks is not uniform on the map sheets of the SMD. Subsequently, a style of rock drawing which best corresponds to the specification of the ladder style representation from the literature and which is the most represented, is selected. The characteristics of these selected rock drawing styles are further described and discussed. Ultimately, the output of this thesis is the determination of such a style of rock drawing, which makes sense to further analyse...

Kryndlerová, Anna ; Čábelka, Miroslav (advisor) ; Lysák, Jakub (referee)
The aim of this bachelor thesis is to create atlas of landscape changes in Lake Most area. The partial goals include evaluation of landscape development within historical context, visualization of land cover structure in 1842, 1938, 1952, 1987 and 2021, and creatation of additional maps, graphs and tables to illustrate land cover development for the whole monitored period. The theoretical part explains the basic concepts related to landscape and land cover and describes the base data layers and methods for analysing and evaluating landscape changes. Furthermore, the rules, concepts and methods of thematic cartography are described. This is followed by the physical-geographical and socio-economic characteristics of Lake Most area and its historical development in regards to coal mining and reclamation. In the practical part, a suitable atlas creation method is proposed based on the acquired knowledge. The key part of the map creation process is working with historical base data layers. The output of the work is a printed atlas of landscape changes in the area of Lake Most, created in ArcGIS and InDesign softwares.

Monitoring land cover changes using satellite high temporal resolution data
Indrová, Magdalena ; Štych, Přemysl (advisor) ; Lysák, Jakub (referee)
The objective of this work is to create a base of spectral characteristics of the monitored vegetation types and to create a classification of the land cover. In this work MERIS images obtained by KAGIK were used. Ten different categories of land cover were selected for the study. The spectral behaviour of all categories for the period April - November 2009 was determined. The spectral response of some defined categories (coniferous forests, developed areas) was stable during the year. Contrary to that, significant changes in the spectral response of agricultural crops were observed. The best results were obtained in the categories Forests and Oilseed rape. Finally, the method of Spectral Unmixing was also tested. This method is used when some pixels contain several cover types. Using this method the best result was also obtained in the category Forests. It is evident that the MERIS images can be used for monitoring land cover changes, but because of the coarse resolution only large and homogeneous areas can be studied.

Musilová, Romana ; Štych, Přemysl (advisor) ; Lysák, Jakub (referee)
Monitoring forest land by using the satellite high temporal resolution data in Czechia Abstrakt Research forest land by using remote sensing data is currently still being developed. This work aimed to evaluate the possibility of using data of high temporal resolution of satellite ENVISAT, specifically MERIS and AATSR sensors. First were identified two model territories, namely Krkonoše and area of Železné hory and Žďárské vrchy. Selected data were preprocessed, then the vegetation indices were calculated, which were used to describe the behavior of forest during the growing cycle, assessment of their health condition and humidity using AATSR data. Anothe part deals with a simple algorithm that would allow the highlight areas of forest to MERIS images. In the end I made a comparison of selected indices of monitoring forest land that type of data. Keywords: remote sensing, forest land, MERIS, AATSR, Envisat
