Computer Support in Mapping Survays
Hanák, Ondřej ; Kočí, Radek (referee) ; Hrubý, Martin (advisor)
The report deals with creating applications for Pocket PC, designed to aid with terrain mapping process. Topic falls within the field of geographic information systems (GIS), so the text begins with an analysis of related topics such as GIS itself, processed data characteristics or global positioning systems (GPS). Available handheld platforms are discussed and based on analysis of existing commercial application, the requirements on developed program are set. Description of application architecture and some implementation details follow. The conclusion is devoted to testing functionality by mapping the real geospatial object.

Regression methods for statistical analysis of spatial data
Klimprová, Lucie ; Šerák, Petr (referee) ; Michálek, Jaroslav (advisor)
Kriging techniques are regression methods used for evaluation of continuous spatial processes. If the covariance structure of process is unknown, then it's necessary to estimate it from the data. The first part of this Master's thesis is devoted to description the kriging method and to estimate of a variogram fuction, which describes the covariance structure of considered process. The second part includes the implementation of kriging method in MATLAB for simulated and real data.

Vizualizace prostorových dat na platformě Microsoft HoloLens
Peřinka, Jan
This diploma thesis deals with the design and implementation of a spatial data display application for the Microsoft Hololens platform. The aim of this thesis is to investigate the possibilities of standardizing applications for augmented reality glasses to ensure portability of applications between devices from different manufacturers. For this purpose, a comparison of scientific works dealing with similar topics and the selection of a suitable standardized format for storing and displaying spatial data was carried out. The result is two applications, one of which allows the user to visualize and interact with data related to his/her environment and the other one allows to display complex geospatial data for any location.

The space data analysis
Burešová, Klára ; Štarha, Pavel (referee) ; Procházková, Jana (advisor)
This thesis deals with the analysis of spatial data and 3D descriptors for object recognition in scenes. The aim of the thesis was to study the issues of working with 3D data and to make a study of different types of 3D descriptors. In this work, we analyzed some descriptors in terms of their ability to describe and quantify the properties of objects in three-dimensional space. Based on this analysis, we selected a suitable descriptor for object recognition in scenes and implemented it. The result of this work is a deeper understanding of 3D descriptors and their applications in spatial data analysis. Our implementation of the selected descriptor provides a basis for further research and development in object recognition in 3D scenes.

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...

Proposal of methodology for Protected Landscape Area maps production
Pekařová, Kateřina ; Lysák, Jakub (advisor) ; Jaroš, Jakub (referee)
Proposal of methodology for protected landscape area maps production Abstract The main goal of this bachelor's thesis is to create a proposal for a methodology for creating maps of protected areas in Czech Republic. The first part of the paper is devoted to acquaintance with the basic knowledge of thematic cartography with emphasis on the basic cartographic rules in the creation of maps. The following is an evaluation of existing maps of protected areas in the Czech Republic and in the world. An overview of data sources is also given. Based on the findings from the first part, the practical part of the thesis then creates the proposal of methodology itself, which is tested on sample maps. Keywords: thematic map, nature conservation, spatial data, cartographic generalization, methodology

A development of the GIS tool for evaluation of population mobility based on mobile phone operators data
Lagner, Ondřej ; Štych, Přemysl (advisor) ; Brůha, Lukáš (referee)
The main aim of the diploma thesis is the facilitation of the monitoring in short-term and long-term migration of population by using processed data of the mobile operator. The diploma thesis is focused on creating an algorithm that allows spatial correlation of positional data from the mobile operator with specific statistical data. In the first part, the reader is introduced to the theoretical background and to the current state of knowledge of the study issues. The methodological part presents the process of designing the tool. The initial phase of the algorithm corrects inadequate topology and the incorrect geometry of input data. The secondary part of the thesis is concerned about the necessary intersection of statistical territorial units and the mobile radio cell stations. During the design of the tool we focused on the user friendliness. The resulting data layers enable the addition of another statistical data or the development of geodatabases.

Line of sight testing
Lutka, Adam ; Skopal, Tomáš (advisor) ; Hoksza, David (referee)
A measurement done for every possible wireless data connection is expensive. It would be useful to reduce the cost. An application which could determine a quality of circumstances influencing possibility of a connection would help to do such a cost reduction. The thesis provides such an application which gives user information about meaningfulness of a real measurement in specific situation. Powered by TCPDF (www.tcpdf.org)
