Technology of GIS in mobile equipment
Laštovička, Josef ; Štych, Přemysl (advisor) ; Čábelka, Miroslav (referee)
The aim of this work is to provide an overview of modern geoinformation systems operating on mobile technology platform. Selected technologies were evaluated by the students of elementary and secondary schools developed using test materials. In the introductory part of the paper briefly describes the current available technology smart phones and tablets focusing comparison platform iOS and Android. The second part of presents an overview of available geo-information software with a focus on free downloadable programs. The third part presents a critical evaluation of the functional parameters of the software. The following are the positive and negative aspects of the applications evaluated and compared to the available free downloadable programs with paid programs. The last part focuses on the possibility of integrating geo-information systems on the platform of smartphones and tablets in teaching primary and secondary schools. Their use in teaching could change students' view of current spatial information systems and could increase their popularity and practical use. Key words: Mobile GIS, smartphone, tablet, GPS, mobile operating systems, iOS and Android.

Testing of altitude accuracy of GIS GPS devices
Žďánský, Radek ; Čábelka, Miroslav (advisor) ; Bayer, Tomáš (referee)
This work is about testing altitude accuracy of GIS GPS receivers Trimble Juno SC and Trimble GeoExplorer 6000 GeoXH. The introduction is dealing with general topics connected with satellite navigation and describes individual global navigation satellite systems. A Separate chapter is dedicated to factors influencing surveying accuracy. The Main section of this work consists of gathering and processing of data gathered from surveying at point with known coordinates and from surveying of an appropriately chosen track. Followed by measurement of chosen leveling program using technical leveling, surveying by GIS GPS receivers was made at chosen points of this leveling program, data gathered from both methods were compared. The results are shown in graphical outputs, where their individual accuracy and suitability for chosen surveying jobs is being discussed.

Creating a 3D model of the White Tower in Hradec Kralove from terrestrial laser scanning data
Lagner, Ondřej ; Čábelka, Miroslav (advisor) ; Štefanová, Eva (referee)
This work is focused on processing data of digital terrestrial laser scanning of The White tower in Hradec Králové city and solving the problems closely connected to this. Data was processed in different graphical softwares, which were specialy made for this kind of tasks. During the processing, the softwares were compared according to established criteria. The mos usefull pragram Geomagic Studio 2012 was chosen and 3D model of the tower was made in this. To assess the accuracy of the model, was it measured by yardstick, and model was also compared with buildings plan.

Mobile GIS in Mapping Land Use
Procházková, Anna ; Štych, Přemysl (advisor) ; Čábelka, Miroslav (referee)
The purpose of this project is to evaluate the possibility of using mobile GIS in mapping land use. Also included is a technical description of the equipment for field mapping (Juno SC and GeoExplorer 2008 GeoXH) and software for collection, editing and updating data in the field (ArcPad and TerraSync). The field research of the current state of land use was carried out as a part of this work. The positional accuracy and availability of the GPS signal were compared with concrete examples of mapped landscape objects. Key words: mobile GIS, GPS, mapping land use

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...

The design of an up-to-date meteorologic situation web portal with the use of satellite images
Hrstková, Lucie ; Grill, Stanislav (advisor) ; Čábelka, Miroslav (referee)
The aim of this master thesis is to create a web portal with the presentation of up-to-date Meteosat images and accompanying aplications. The web portal is intended for a "common" user. It will contain a registry of events which are interesting in terms of meteorology (storms, various types of clouds, etc.) as well as descriptions of different meteorologic situations and objects in images. Except for the presentation of the images, this web portal will provide its users with a database of previous images, which can be displayed, links to other websites with a similar topic, informations about the satellite where these images were taken from and the opportunity to display the images of interesting or rare processes. A commentary on the up-to-date situation will complement the presentation. Powered by TCPDF (www.tcpdf.org)

Possible usage of SVG and JavaScript for interactive maps
Stein, Zbyněk ; Čábelka, Miroslav (advisor) ; Schneider, Michal (referee)
The aim of this work is to demonstrate the possibilities of the SVG format and JavaScript in creating of interactive maps. The work is primarily focused on the creation of various elements of the digital interactive map. In the theoretical part of the work the attention is paid to the term of the interactive map and its integral components. The possibilities of use of both selected formats are described. The development of both formats and the way of their implementation are also mentioned. Other techniques used in the practical part are briefly listed. In the next part of the work the creation of the interactive map elements and the useability of the selected formats in practice are discussed and evaluated. The results are also demonstrated in the sample interactive map. Powered by TCPDF (www.tcpdf.org)
