Calculation of local quasigeoid models from heterogeneous data
Kratochvíl, Richard ; Kostelecký,, Jakub (referee) ; Weigel, Josef (referee) ; Kratochvíl,, Vlastimil (referee) ; Machotka, Radovan (advisor)
The goal of this thesis was to evaluate whether it is possible to replace gravimetric data with topographic ones for calculating quasigeoid models using astrogeodetic levelling. Gravimetric data are not of sufficient quality in selected areas, hence their replacement can increase the accuracy of obtained models. The computational program PRVAK was created. It facilitates the calculation of the quasigeoid model by astrogeodetic levelling, the models can be calculated on a profile or in an area by least square adjustment of conditional observations from astrogeodetic deflections of the vertical or their combination with topographic ones. Furthermore, the Dolní Morava network was built, with astrogeodetic deflections of the vertical determined at 34 points. The data comparisons were tested at three localities, where quasigeoid models were calculated by astrogeodetic and astrotopographic levelling and compared with reference data. On the profile Velká Bíteš – Brno – Uherské Hradiště, the calculated models were compared with the gravimetric model calculated by Research Institute of Geodesy, Cartography and Topography. The standard deviation of the differences between the reference model and the models calculated in this work was reduced using astrotopographic levelling by approximately 38 % compared to astrogeodetic levelling. For area models of quasigeoid in the localities of Dolní Morava and Brno, it was possible to compare the internal accuracy of these models. When using astrotopographic levelling, values of standard deviation of height anomalies were reduced by 40 % in Dolní Morava locality and 25 % in Brno locality compared to astrogeodetic levelling. In both localities, the quasigeoid QGZÚ-2013 was chosen as a reference model for comparison of external accuracy. The contribution of astrogeodetic levelling to the improvement of external accuracy could not be demonstrated because the calculated models of quasigeoid have similar accuracy as the reference model.

The diploma thesis concerns of the creation of building design documentation of the agricultural building in Mutěnice with using building information modelling in Autodesk Revit. Drawings are made normative by ČSN 01 3420 and with using of the results of laser scanning. Text part contains description of whole process, starting with field survey and collecting data, throughout processing of point cloud, ending in modelling of the building and terrain surface and building design documentation creation. The definition and application of BIM on the present is attached to the theoretical part. Main output production data is the building design documentation.
The creation of construction drawing documentation of a terraced house in Mutěnice
Pittauerová, Petra ; Kratochvíl, Richard (referee) ; Kuruc, Michal (advisor)
The aim of this master's thesis is to create construction drawing documentation for the main part of a terraced house in Mutěnice based on a BIM model and to create a thematic map in the vicinity of this family house. To create the required attachments, on-site measurements were conducted using geodetic surveying techniques, including GNSS technology, tachymetry, and laser scanning. The key focus of the thesis is to describe the on-site and office work that was essential for creating the necessary outputs. The main output of the thesis is the construction drawing documentation of the main part of the family house at scales of 1:50 (floor plans, sections) and 1:100 (elevations). The thematic map is made at a scale of 1:250 in the coordinate system S-JTSK and the altitude systém Bpv. Due to the owner's privacy protection, the created BIM model is not included in the thesis attachments and will be provided solely to the owner of the family house. The outputs of this thesis represent the actual state as of August 2022 and will serve as a basis for the planned reconstruction.
Survey and preparation of a large-scale map in the cadastral district Malhostovice - locality Zlámaniny part A
Orviská, Terézia ; Kratochvíl, Richard (referee) ; Vondrák, Jiří (advisor)
The theme of this bachelor's thesis is mapping and creating of a purpose map in the cadastral area of Malhostovice – locality Zlámaniny. The measurement is connected to the binding reference systems S-JTSK and Bpv by the GNSS technology in combination with the use of the state point field. The final map at a scale of 1: 500 is made in accordance with ČSN 01 3410 and ČSN 01 3411. The work provides a theoretical introduction to the issue with a subsequent detailed description of the work.
Corrections of systematic errors and map update of JDTM ZK in the locality of Slavkov pod Hostýnem - the southern part
Chladil, Martin ; Cimpl, Pavel (referee) ; Kratochvíl, Richard (advisor)
This bachelor's thesis deals with a revision of the digital technical map of the Zlín Region (JDTM ZK) in the chosen locality in pursuance of its improvement. There are localities with big systematic errors areas designated for solving by the administrator of the map. Uniquely defined points are measured with specified accuracy and range. Deviations of these points are evaluated. Erroneous areas of the thematic map of surface situation are transformed, topologically neaten and data from revision survey are added.
Revision and survey of large scale thematic map of the surface situation
Fodor, Alexander ; Kratochvíl, Richard (referee) ; Kalvoda, Petr (advisor)
The main content of this bachelor’s thesis was updating the surface map in the Staré Hradište 2 location. The update was performed using a mobile mapping system. The GeoStore V6 programme by GEOVAP, spol. s r.o. was used to process point clouds. After evaluating the point clouds, the areas insufficiently covered by the point clouds were measured using the polar method from positions whereby the coordinates and heights were determined by the GNSS-RTK method. The resulting map was tested according to ČSN 01 3410 and the advantages and disadvantages of both data collection methods were compared at the end of the thesis. The resulting map was checked by GEOVAP, spol. s r.o. and subsequently entered into the Digital Technical Map of Eastern Bohemia database, which is handled by the Association of Network Administrators of Eastern Bohemia.
Surveying and production of a special map of a part of the Luba creek valley (cadastral area Malhostovice)
Veselý, Milan ; Kratochvíl, Richard (referee) ; Vondrák, Jiří (advisor)
The aim of this bachelor's thesis was to make a purpose map at a scale of 1: 500. The locality of the Luba brook was given as a locality for mapping. The tachymetry method was used for detailed mapping. The performed measurement was connected to the binding reference systems S-JTSK and Bpv. After calculating the coordinates of the detailed points, a topography was created and the data were transferred to a DMT triangular network to represent the elevation. All work was carried out in accordance with standards ČSN 01 3410 and ČSN 01 3411.
