Web Application for Visualization of Values in Geographical Coordinates
Kašpar, Petr ; Bartík, Vladimír (referee) ; Hynek, Jiří (advisor)
Data visualization in maps is a technique of data presentation, which displays spatially-bound variables. The objective of this thesis is to create a web application capable of creating visualizations of data in geographic coordinates, enabling user to analyze observed phenomenon in many different levels of view, ranging from the general overview of patterns to the analysis of fine details. The Geovisto library is capable of visualization of generic data and their connections but these visualizations are limited to the territories of states and do not work with exact geographic coordinates. This is inconvenient for some kinds of data analysis and makes visualizations of data sets that work with exact coordinates impossible. I focused on extending this library by map layers capable of visualizing data in exact geographic coordinates.

Web Application for Graphical Visualization of Geospatial Time Series
Rykala, Kryštof ; Rusňák, Vít (referee) ; Hynek, Jiří (advisor)
Geografická data se stala nedílnou součástí každodenního života. Nejběžnější vizualizací geografických dat je statická tematická mapa. Ta ovšem vizualizuje pouze jeden časový okamžik, případně několik z nich, agregovaných dohromady. Bez času navíc není možné vizualizovat geografické jevy, jako je vývoj různých geografických charakteristik (např. růst emisí uhlíku nebo šíření viru). Cílem této práce je vytvoření nástroje pro vytváření vizualizací geografických časových řad, které umožní data prezentovat a studovat. Řešení je vyvinuto jako nástroj aplikace Geovisto. Vyvinutý nástroj umožňuje uživatelům vytvářet vlastní vizualizace a animace geografických časových řad a zároveň je konfigurovatelný pro použití s obecnými daty. Uživatelé se znalostí programování mohou vytvářet nové Geovisto nástroje (např. tematické mapy) a pomocí nástroje pro práci s časem sami implementovat animace do nových tematických map.

Usability Improvement of Geovisto Library
Koscielniak, Tomáš ; Rusňák, Vít (referee) ; Hynek, Jiří (advisor)
This thesis aims to improve the user interface of Geovisto library, used for geospatial visualization. This is achieved by identifying issues using user testing and designing a solution for them. These solutions were implemented, and the second user testing tested their benefit. The result of the thesis is expanding the library with legends, units for numerical values, and tools for visualization of metadata, which all improve the user experience when using the library. Another result is a standalone web presentation of the library, its tools, and data miner.

Graphical Visualization of Network Traffic Geographical Data
Kachlík, Jakub ; Holkovič, Martin (referee) ; Hynek, Jiří (advisor)
During ongoing Internet attacks is important to find out as much information about the attacker as possible and to pass this information clearly to the network administrator. The Flowmon monitoring system is currently able to determine the source destination of sent packets, group them into flows and write them into a table. The data visualized in this way are confusing to create a geographical analysis of the attack. The objective of this work is to create a web information dashboard that will display geographic visualizations of network traffic. It will provide more detailed and easier-to-understand analysis to users of the tools.

Interface for Automatic Tests of Geovisto Library
Dohnal, Lukáš ; Burget, Radek (referee) ; Hynek, Jiří (advisor)
The aim of this master thesis is to design and implement an interface for automated testing the Geovisto library. The interface should allow efficient and user-friendly testing the library during its development. The thesis includes a survey of libraries to test projects in programming languages JavaScript and TypeScript. The thesis includes the development of tests of current modules of the Geovisto library and the library profiling, which will be used to propose possible changes in the implementation to improve library performance.

Information System for Management of Geographical Data Visualizations
Grossmann, Jan ; Rusňák, Vít (referee) ; Hynek, Jiří (advisor)
The goal of this this is to create an information system for the visualization of geographical data. The main idea is to allow users to create visualizations with their own geographical data, which they can either import from files or directly attach their own database system as a source of data and make use of the data in real-time. The result will be a new web information system that will act as a point of contact between users, geographical data, and visualizations.
