Geometric plan in the process of complex landscaping
Vojtková, Gabriela ; Bonacina, Tomáš (referee) ; Bureš, Jiří (advisor)
This bachelor thesis deals with the issue of comprehensive land consolidation with a focus on surveying activities, which are an essential part of it. It evaluates the methods used, the results achieved, and their accuracy. The first part of this thesis describes the legislation, the actual process of comprehensive land consolidation, and the types of geometric plans that are prepared during the land consolidation process. In the second part, the documentation for the preparation of a geometric plan and the recording of detailed measurements of changes, as well as their preparation, are described. The result of this work is the preparation of a geometric plan of the area of comprehensive land consolidation in the cadastral territory of Dunice pod Ralskem.

Revision of Minor Geodetic Control within the Complex Land Consolidation
Staško, Samuel ; Drápela, Zdeněk (referee) ; Bureš, Jiří (advisor)
The aim of the work is to carry out in cooperation with Ageris s.r.o. a revision of the detailed position point field (DPPF) and its subsequent completion for the needs of the complex land consolidation (CLC) in the cadastral area of Hřivinův Újezd. The basis for the revision of the DPPF was geodetic data. The existing points of the DPPF were identified during the field visit and located using the local descriptions and measurements indicated in them. Their location was verified by GNSS-RTK measurements. From the results of the review, documentation was prepared, which also included a proposal for the addition of the existing DPPF. After the proposal was approved by the Land Registry Office in Zlín, the new geodetic points were stabilised and geodetically surveyed using the GNSS-RTK method, occasionally by terrestrial means. After the completion of the field measurement work, the appropriate documentation was prepared for the newly added geodetic points of the DPPF, which was subsequently adopted into the technical documentation of the Zlín Land Registry Office.

Land take documentation of line constructions
Klekar, Martin ; Alferi, Kamil (referee) ; Bureš, Jiří (advisor)
The subject of the work was the documentation of the land take of the linear construction - roundabout in Přerov - from the sample data of ŘSD s.p., description of the processing procedure and comparison of the results of the SW. Firstly, the general principles of land take and the types of data entering into the creation of the land take elaboration are explained. Next, the processing of data and preparation of data for the SW and production of outputs is described. This is followed by an introduction to the resulting workbook, its structure, and individual components. The principle of the checks to which the produced work is subjected is also presented. The work included the preparation of the land take elaboration in several available SW and comparison of the results. An overview of the SWs enabling the preparation of the elaboration is given. The four SWs in which the elaboration was prepared are described in detail and the outputs of the programs are evaluated.

Information modeling of selected objects of the railway transport route to DTMŽ
Paruza, Filip ; Raška, Jakub (referee) ; Bureš, Jiří (advisor)
The aim of this work is to acquire field data of selected objects of the railway transport route. These are objects such as railway underpass, concrete, prefabricated and steel bridges, plate, beam or arch bearing constructions. The data are acquired using terrestrial positioning systems (TPS) and terrestrial laser scanner (TLS). The data thus acquired are processed into a 3D model of Digital Technical Railway Map with an evaluation of the accuracy and efficiency of the procedures used.

Dynamic modelling of active railway traction feeders for power quality assessment
Bureš, Jan ; Doleček, Radovan (referee) ; Klusáček, Jan (advisor)
The thesis is focused on modelling of traction feeders for 25 kV 50 Hz traction system in order to assess the influence on voltage quality at point of the connection in 110 kV distribution grid. With respect to various technology of traction feeders, the feeder models, including conventional feeding system and modern converter stations, emphasize operating principle, detailed power circuit structure and description of influence on voltage quality in the distribution grid. The selected technologies of traction feeders are modeled in simulation software PSCAD and influence on voltage quality at the point of connection is assessed via an example, which reflects a realistic operation of traction vehicles in the typical traction system. The models are parametrizable and thus can be used for the connectivity assessment for the distribution system according to national distribution system operators’ standard PNE 33 3430-0. Moreover, the thesis also deals with the use of modern converter feeders for auxiliary frequency services. The operation principle is demonstrated on examples where the basic algorithm and requirements for control layer of converters is described. Finally, an algorithm for synchronization of the feeders supplying adjacent 25 kV 50 Hz railway traction system sections is designed and presented by means of simulation. In general, the thesis shows the use of dynamic models for connectivity assessment to the distribution grid in pre-project phase and for definition and development of converter feeders use cases upon feeding of the railway traction system.

Precise Positioning of Railway Primary System Using Gnss Technology in Operating Conditions
Bureš, Jiří ; Vystavěl, Ondřej
The paper deals with the analysis of the accuracy of the real-time GNSS measurement procedure used in railway operating conditions. The accuracy achieved in operating conditions is compared with the accuracy obtained on a calibration base using the same measurement procedure. The consistency between the accuracies of the primary system (satellite-determined) and the secondary system (terrestrially measured by the traverse method) is also discussed. The analysis includes the problem of residual inhomogeneities of the uniform transformation key when transformed to S-JTSK.

Railway track deformation measurement
Leischner, Ludvík ; Bureš, Jiří (referee) ; Švábenský, Otakar (advisor)
This bachelor thesis is about measuring deformations on railway bridge in Znojmo. The horizontal and vertical changes of railway track on the bridge and newly renovated bridge construction were measured by using two independent methods, namely 3D polar method and kinematic GNSS Stop & Go method. The assessment of the longitudinal shifts depending on atmospheric conditions especially the temperature changes is an essential goal of this work. Another key aim is the determination of precision of both independ-ent measuring methods.

Surveying and Elaboration of Technical Map of the Locality of Matyáš Lerch Gymnasium.
Adámať, Martin ; Nádeníček, František (referee) ; Bureš, Jiří (advisor)
Bachelor thesis describes the creation of the technical map of situation around Matyáš Lerch´s high school in Brno. The thesis describes all stages of the procces of creation. Starting by reconnaissance, preparation of the survey, creation of surveying network, measurments in the network, large-scale mapping, data processing, map creation and data analysis. The main aim of the thesis is creation of technical map and the creation of surveying network. The network will be used by Brno University of Technology´s Faculty of Civil Engineering for later use of teaching students. The thesis also describes reliability of chosen surveying methods. The map was created at scale of 1:500. The map was created using instructions ČSN 01 3410 and ČSN 01 3411.

Deformation Measurement of Roof Structure
Hubáček, David ; Švábenský, Otakar (referee) ; Bureš, Jiří (advisor)
The thesis deals with the evaluation of displacements and deformation of the large span wooden roof structure of the aquapark hall in Brno - Kohoutovice. The task of this work is to compare and verify the applicability of the laser scanning method for the evaluation of displacements and deformation. The comparison was performed with regard to the polar method with quantities measured by the total station. As part of the work, two-stage measurements were performed on the basis of which a comparison of both methods was performed. The data obtained by the polar method were processed using LSM, the data from laser scanning were processed in an Excel spreadsheet. A comparison of the two methods shows that we have achieved a similar level of accuracy with the laser scanning method when compared to the polar method. It is therefore possible to use the laser scanning method to measure displacements and deformation.
