Track's Elevation Profile View on a Public GIS
Doubal, Štěpán ; Šilhavá, Jana (referee) ; Fapšo, Michal (advisor)
This bachelor's thesis describes the design and implementation of a user script for GreaseMonkey (plug-in for Firefox). This script adds a functionality to show height profile of a defined route. The route is defined using public GIS tools from www.mapy.cz. The script extracts coordinates from page DOM structure, processes it and draws a height graph. The graph is created using http://www.heywhatsthat.com/profiler.html [2] or www.profile.hy.cz, which provides height graph drawing using www.vyskopis.cz JavaScript API [4].

Online route planning with open-source applications
Matyáš, Jiří ; Schneider, Michal (advisor) ; Brůha, Lukáš (referee)
The goal of this work is to create a route planning web application while using open source tools and applications. In the beginning, tools used to produce such application are briefly introduced. The the process of creating the application is described. This paper describes the proces sof getting, editing and storing data used for route planning. The proces sof creating the web mapping application itself is described, too. Data have been stored using PostgreSQL database system and its extension PostGIS. Route planning is realized using pgRouting library and the resulting route is displayed using OpenLayers library and OpenStreetMap as a base map. The application has been created using PHP and Javascript.

Security of publishing spatial data on Internet
Břichnáč, Pavel ; Čábelka, Miroslav (advisor) ; Grill, Stanislav (referee)
Bezpečnost publikování prostorových dat na internetu Abstrakt Diplomová práce se věnuje problematice publikování prostorových dat v síti internet. Cílem je popsat soudobé způsoby publikování dat, analyzovat bezpečnostní slabiny z hlediska úniku dat a navrhnout opatření, která by umožnila zabezpečit volně dostupná data proti automatizovanému stahování. V práci je vysvětlena motivace ilegálního získávání prostorových dat, jsou popsány soudobé možnosti publikování dat na internetu (včetně specifik pro data rastrová a vektorová), možnosti ochrany dat proti nelegálnímu získání a jejich slabiny. Výsledkem je navržení a formulování obecné metodiky ve formě doporučení pro publikování různých typů prostorových dat, která automatizované útoky na získání dat významně ztíží. Klíčová slova: prostorová data, internet, mapový server, datová politika, webové technologie Security of publishing spatial data on the Internet Abstract The master's thesis focuses on the topics of security of publishing spatial data on the Internet. The goal of the work is to describe present ways of publishing, to analyze weaknesses from point of view of leaks and to propose measures, that would allow securing publicly accessible data against automated downloads. Readers will get explained the motivation of getting spatial data, description and...

Možnosti využití historických podkladů pro potřeby pozemkových úprav
HERBSTOVÁ, Terezie
The bachelor thesis is focused on historical background od landscaping needs. Primarily, the thesis deals with online applications of maps, which are available on various maps servers. It is divided into two parts; the first of them is supposed to be a literary research and the second part is a research of accessible maps based, mainly from online maps. Data were collected by analyzing available backgrounds such as literature and websites based on maps or WMS accesibility. By exploring the maps data, I have created a list of the most well-known and the most important maps servers for the need of land consolidation.

Modelování a vizualizace vymezeného geografického prostoru s možností interaktivního zásahu do modelovaného procesu
Procházka, David
Effective management and sharing of geodata is one of the priorities of governments and companies all around the world. Nowadays spatial data are published without any standardized methodics and unified metadata. This situation leads to multiple storing of such geodata and consequential high expenses and inconsistency. There is usually a problem even find an appropriate mapserver with the required data. Obviously there is a problem: How to access geodata more effectively. We are searching in emails, discussions, documents around the web, even in pictures. But currently there is no searching engine for geodata which could be compared with well known searching services such as Google, Yahoo!, etc. Therefore I focused on this issue. The first part of this work briefly presents standards used for publishing geodata. A review of methods used for geodata and metadata aggregation follows. Based on this review, a method for development of an engine for geodata search is presented. Last part describes principles of experimental implementation and achieved results.
