Path Finding in the Vector Data in OpenStreetMap Project
Adamček, Adam ; Procházka, Boris (referee) ; Váňa, Jan (advisor)
Pathfinding services are nowadays often used by people to plan a route through an unknown area. This bachelor's thesis deals with designing and implementation of an application which is able to search in free map data provided by the OpenStreetMap project and visualize resulting paths. During the search, not only the way types, but the selected transport type and the attributes of the eventual route will be taken into account as well. The work also contains an analysis of the OSM format and the proposal of a custom, more compact format useful for storing the preprocessed data. Eventually, the implemented application's performance is tested and its output is compared with other commonly used routing solutions.

Support of Mapping by Image Processing
Jaroš, Ján ; Herman, David (referee) ; Váňa, Jan (advisor)
This bachelor's thesis deals with methods of detection of selected objects in video and with importing these objects into OpenStreetMap central database based on their geographic location. It focuses mainly on recognition of road signs. First section briefly describes some of the most widely used methods and OpenStreetMap project itself. In the following chapters is given a more detailed overview of used methods of proposed system, its implementation and testing. The conclusion contains evaluation of whole work and the possible improvements are listed here.

Mapping of Road Signs Using Image Processing Methods
Leško, Vladimír ; Drahanský, Martin (referee) ; Novotný, Tomáš (advisor)
The following Bachelor's Thesis deals with traffic sign recognition in video clips, obtaining GPS records and inserting traffic sings with accurate GPS co-ordinates into OSM central database. In each of Thesis' chapters are in sequence introduced methods of image detection and classification, consecutive familiarization with OSM project and its JOSM plug-in. Afterwards there will be presented an application and an applicative plug-in design and implementation process. The final chapter is represented as the results of testing the application in 10 video clips. The conclusion contains an evaluation of the Thesis with possible extensions.

Editor for Traffic Simulator
Malaník, Michal ; Snášelová, Petra (referee) ; Rozman, Jaroslav (advisor)
The aim of this work is to create an editor of intersections with a graphical user interface for Brno traffic simulator. As an input of the editor is used file of geographic data, which is downloaded from the freely available database of server OpenStreetMap. At first are in downloaded geographic data detected intersections. The detection is performed using a detector, which was also created within this work. Editor then allows to edit the intersections to be as much as possible accurate. This process involves modeling the number of lanes, layout and types of traffic lights and also traffic detectors and many other real-world objects. The edited data are then made available in the form of an output file in XML format and are hereby provided for the traffic simulator.

Map Creation Application from OpenStreetMap Project Data
Latta, Martin ; Rozman, Jaroslav (referee) ; Novotný, Tomáš (advisor)
This bachelor's thesis deals with the development of application that allows you to create maps from OpenStreetMap project data and change their appearance. The work contains an introduction to cartography, information about OpenStreeMap project and rendering library Mapnik. The main focus of the text is a description of the design and implementation of the application itself, including the final testing and evaluation.

Web Editor for GPX Data
Hendrych, Petr ; Bartík, Vladimír (referee) ; Burget, Radek (advisor)
The aim of this bachelor thesis is to create a web editor, which will allow the user to view and edit their recorded routes in GPX format. For each route, the user can adjust the position of the selected point, add another or delete an individual point or a selected group. The client part of the application is written in Javascript using the React library. The server part is implemented using the Django framework and the GeoDjango module. Communication between these parts is provided by the Django REST framework. The results of this work allow users to easily edit their tracks in a web browser.

Management Application for Touristic Routes in OSM
Švaňa, Petr ; Michal, Bohumil (referee) ; Kašpárek, Tomáš (advisor)
Bachelor thesis deals with alalysis of Czech Tourist Club hiking routes and checking their data validity in OpenStreetMap internet map source. In the resulting application has user at his disposal visialized OpenStreetMap data and implemented gadgets to simplify the control of these data. First, introduction to this topic is discussed including information about both data model, that OpenStreetMaps uses, and mapping of the tourist trails. Second, analysis of current ways for map data checking along with development of the application, that can bring these controls into practice are concerned. In following chapters, created implementation of the application with detailed manual can be found.

Building Model Generator for Open Street Maps
Galacz, Roman ; Poulíček, Zbyněk (referee) ; Polok, Lukáš (advisor)
This work concerns obtaining data from the maps provided by the project OpenStreetMap. The data are converted from the format of geographical latitude and longitude to the Cartesian coordinate system. This work also concerns building type recognition in build-up area which are situated on the downloaded map. Part of the work is a demonstration application which is able to model 3D geometry of the buildings, based on the results of the recognition algorithms and also creates a terrain in which these buildings are situated. Generated model is displayed using the OpenGL graphics library.

Augmented Reality on Android - Displaying of Map Features in Terrain
Halás, Timotej ; Kapinus, Michal (referee) ; Herout, Adam (advisor)
The aim of this thesis is to create an application of augmented reality for Android operating system. Based on the preview from the camera, map data and the location of the device determined by the GPS module, a scene is created showing additional tourist information in the field. As a source of information and altitude data, the OpenStreetMap map and the Google Elevation API are used. The position in the Cartesian coordinate system is determined by geographic location using the WGS84 geodetic system. LibGDX game framework is used for rendering. The resulting application was tested in the field and it is useful in getting to know the surrounding landscape. It has also helped to navigate to points of interest by displaying their distance from the point of observation. The result of this thesis is an application suitable for exploring the observed environment.

Puerto Argentino, inhabited by the pirates and drunkards of the royalty
Mlynarčík, Štefan ; Mrva, Jozef (referee) ; Rathouský, Luděk (advisor)
Objectivity and neutrality of current makers of online maps is hampered by the fact that the most important of them who form the public opinion are largely commercial giants. Sensitivity of approaches is desirable especially in specific situations involving territorial disputes. The textual part of the thesis brings theoretical insights to the problematics of map makers policies and their preservation or violation. At the same time is describes critical cartography as a current opposition against governmental and cooperative mapping, of which counter-mapping processes are regularly used in art, too. Practical outcome attempts to reflect specific approaches of map makers depending on particular territorial disputes. It takes place mostly in online environment, using the functions of Google Street View or Google Earth and forms of counter-mapping on the OSM platform. The goal is to bring alternative realities complicating map makers policies and governing apparatus to map projects with the international coverage.
