Abstract:
Railway tracks require more thorough maintenance and analysis than regular roads for cars. Defects are here noticed and recorded by using special equipment. Construction of railway roads and their exploitation requires optimal accuracy and monitoring of surveying. It is related to maximum allowed speed of trains, the environment, transport and human safety. In order to highlight complex problems of railway road exploitation, the evaluation of railway roads was conducted. Problem areas of railway maintenance were identified. Their monitoring needs to be improved by applying geodetic devices for surveying. Comparing analogous surveying conducted using EM140 machine with that of geodetic equipment, one can see the advantage of geodetic surveying. Technical gaps in the surveying process, data storage and procession were evaluated as well. It was discovered that maintenance and monitoring works should be pursued more frequently using high accuracy geodetic equipment. Key words: railway, geodetic surveying, accuracy of surveying, EM140.

Abstract:
AbstractModern scanners can perform terrestrial topographic survey with resolution of 1 cm and accuracy of 2 mm in just a few minute‘s time, from the distance of up to 100 meters. However, for surface topographical surveying of large territories or complex industrial objects, it is necessary to conduct geodetic traverses and perform their binding to the points of the geodesic basis. One method of coordinate transferring during surveying is by using the method of inverse linear-angular intersection, which involves the measuring of the respective sides S1, S2 and the β angle between them. This method is more precise than the classical one, which usually contains centring and reduction errors. The linear-angular intersection method can also be used for many applications in engineering geodesy, for laying geodetic traverses, and for binding to the wall based points of ground-surveying.

Abstract:
Studies in the Tallinn University of Technology are based on a modular system, where geodetic surveying comprises a self-contained study module in the curricula of all civil engineering specialities. Due to geodetic surveying being taught to all first year students of civil engineering, it serves as a touchstone to test a student's suitability for an engineering specialism. Future civil engineers are taught basic geodetic measurements and how to use optical theodolite, levelling instrument and laser level. The paper gives an overview of geodetic surveying lectures, laboratory classes and field survey camp. Teaching and assessment are based on learning outcomes. Students who have passed the exam are allowed to participate in the summer field survey camp, the aim of which is consolidating the knowledge acquired throughout the year and practising teamwork.

<p>Surveying is an important part of any archaeological research. In this paper we focus on the archaeological research in north Sudan (6<sup>th</sup> Nile cataract) and the surveying methods applicable under the local conditions. Surveying in the Third World countries is affected by the political situation (limited import of surveying tools), local conditions (lack of fixed points, GNSS correction signal), inaccessible basemaps and fixed point network. This article describes the methods and results obtained during the three archaeological seasons (2011-2014). The classical surveying methods were combined with KAP (Kite Aerial Photography) to obtain the desired results in form of archaeological maps, detailed orthophoto images and other analyses results.</p>

Abstract:
Abstract The aim of this paper is to present the need for changes of geodetic-legal procedures for the cadastre and real estate management. This problem was analyzed both in theoretical and practical terms. In order to better present the analyzed technical and legal procedures, a study of several cases of surveying documentation was made. On their example the problems associated with the surveying services were shows and the formal and legal procedures, on the basis of which described surveying works were done were verified. The problem presented is current and valid not only for the comfort of the surveyor's work, but also from the point of view of the structure and modernization of the real estate cadastre, constituting the backbone of the real estate management. The article emphasized the need to unify the databases of state registers and the digitization of the National Geodetic and Cartographic Resources (PZDGiK). Research has shown that despite the continuous changes of legislation, there are still many shortcomings and gaps, which often complicate the surveying works. The surveyor must analyze and verify all materials he uses, including those obtained from the Centre of Geodetic and Cartographic Documentation (ODGiK). The quality of the geodetic and cartographic elaboration depends largely on the work of the Centre of Geodetic and Cartographic Documentation. The need of modernization of the Land and Buildings Registry, which acts as a cadastre in Poland, has been demonstrated. Furthermore, the unification of data used as reference systems both for plane coordinates and elevation has been proposed.

Abstract:
Abstract: modern geodetic technologies allow us to quickly obtain relevant, precise and reliable geospatial data. An example of such a technology is ground-based laser scanning. Currently, this technology is actively used in the performance of engineering and geodetic surveys of roads. The devices and software of different companies are used, differing in their accuracy characteristics and functionality. The article focuses on the experience of the use of GLS-1500 ground-based laser scanner produced by TOPCON and ScanMaster ground-based laser scanning data processing software for engineering and geodetic surveys in order to repair nine sections of the Federal highway R-256 "Chuysky tract" with a total length of over than 100 km. The article also describes the options used for registration of scanning data, the features of their use depending on the availability of geodetic control on the object. The order of processing the results of ground-based laser scanning using ScanMaster software is considered. According to the results of field work on ground-based laser scanning of nine sections of the R-256 highway, the time and accuracy of scanning data were estimated. The method of estimation of time spent on scanning works is also described. The issue of evaluating the accuracy of obtaining the scan data in the ScanMaster software is considered. It is noted that the accuracy of the geodetic reference, thus, the accuracy of the absolute orientation of the scans can be estimated by the differences between the coordinates of the marks that were scanned from the location of the device and calculated by ScanMaster software, and their specified values obtained from the equalization of the geodetic control. In conclusion, it is stated that the optimal time and accuracy of scanning with GLS-1500 device are achieved by using the geodetic reference of the scans by the inverse length-angle intersection at two points of the geodetic control.

It has been proposed that if a vascular prosthesis is to more closely approximate the mechanical behaviour of a native vessel, it should similarly feature a multi-component structure. One of the components could be a metal support structure, similar to an endovascular stent. The objective of the project was to develop a numerical tool, using the Finite Element Method (FEM) to aid in the development and optimization of such a metallic support structure. This tool was used to simulate the behaviour of different designs under the simulated in vivo conditions. The numerical results of the predicted mechanical behaviour are then analysed.

The purpose of this research was to identify how the distribution and availability of spatial data could be improved. This should then minimize the duplication of data and ensure a better utilization of available data sources. All decisions that are made should be based on information, and especially decisions about our natural resources should be based on geographical information - this is spatial information of our environment. Many users, however, are not aware of the spatial data available or where to find it. In Chapter 2 the literature review reports on the spatial data sources in other countries, and different methods that are used to make this data available to the users. Most of the research was done on the distribution of digital data, and not much on traditional non-digital material. The establishment of national land information systems and data sharing via the networking of databases is receiving wide attention. An investigation was done to establish the spatial data suppliers and the data users, the types of data supplied, and the requirements. Three possible methods were investigated to improve the distribution of spatial data and•to reduce the duplication of data: a comprehensive GIS with a full database; a national spatial data infrastructure (NSDI); a metadata base.

This thesis report discusses the design, implementation and testing of a non-contact measuring tool based on the principle of stereo photogrammetry. The system uses a pair of CCD video cameras and a frame-grabber in a PC to capture the pair of images this requires. The software on the PC then measures the image co-ordinates of points selected by the user and transforms them into space co-ordinates for the points. The transformation requires knowledge of the relative positions and orientations of the cameras. This is found in a calibration stage from images of a calibration frame. The cameras are mounted on a bar, which guarantees that the relative positions and orientations of the cameras remain invariant within certain limits. This makes the system portable.

Abstract:
Bibliography: leaves 64-65.
This thesis describes research and development work which led to algorithms, procedures and computer programs which facilitate the cost effective and accurate capture of geometric data. The geometric data for a Geographical Information System (GIS) at a local authority or municipality consist of a number of different data sets. These include inter alia: the cadastral information, zoning information, servitudes, building lines, the outlines of improvements and the reticulation networks and the house connection points of the engineering services. The initial capture of the geometric data appears to be deceptively simple and is often not given the required consideration. The initial data capture phase of GIS projects is usually a difficult and time consuming process. This is even more so in the case of GIS for local authorities. The reason for this difficulty is the large volume of data coupled with the high accuracies required for the cadastral base map and the engineering services. Input facilities of most commercial GIS software packages generally do not provide the most efficient means of data capture. This problem warrants the development of techniques and procedures specific to local authority GIS applications which ensure that data capture can be done effectively and efficiently. The major benefit of these procedures is that they can be implemented on personal computers with low random access memory capacity. This eliminates the need for investment in costly equipment at the initial stage of data capture in the development of a GIS. It allows the capture of data on low cost technology and the postponement of the purchase of an expensive system or workstation until the data capture phase has been completed. The lowest personnel skills required are copy typing in contrast to the traditional methods of using CAD operators who command higher salaries and require more expensive training. The system developed by the author is more productive, both in quality and volume of work produced, than the CAD approach. It also permits the delay of purchase and training on expensive GIS software and hardware, which may be obsolete by the time the graphic database is established.

Transnet possesses approximately 60000 land parcels covering the whole of the South African rail network. These parcels, or polygons, will form the base map in a corporate Geographic Information System (GIS) which will be used for property administration and general railroad operations management. Accuracy requirements are high and unique coordinate values have to be determined for each polygon apex before data are input into the GIS. Railroad property portfolios are characteristically configured in long thin strips. The solution therefore has to cope with poor geometry. The method used to determine apex coordinates must be time and cost efficient, and produce acceptable levels of precision. This study examines the feasibility of using a particular mathematical model with the least squares method in the partial automation of the determination of unique points from sets of differing and, at times, conflicting cadastral data for the creation of a digital cadastral database. The approach is not a mathematically rigorous conventional survey network solution, but a pragmatic application of least squares and network principles, to suit the nature and limitations of the data.

Abstract:
Bibliography: pages 51-53.
This thesis reports on the design, development and testing of a semi-automated system to aid in the mapping of the interior of industrial plants. The system makes use of digital photogrammetry to assist an operator in locating and identifying components of the plants. All of the important photogrammetric theory is discussed in the text, and explained in detail in the appendices. Specifically, this system implements various algorithms used for camera calibration, object point intersection, and a method combining the two techniques. Considerable use is made of the iterative least squares method, which is the basis of many of the algorithms employed in this work. Image processing algorithms are implemented to enhance the digital images, and to ease the identification of objects in the images, and these are fully explained in the text. Adaptive least squares image matching is a method of matching corresponding points in different images and is used to ensure correspondence between points identified by the system operator. A weighted centre of gravity method is used to find the centre of target areas, and an algorithm is implemented to determine the radius, centre and direction of a pipe passing through a number of points. Various aspects of the system design are discussed and explained. In particular the requirements in terms of hardware and software are presented. In addition, the choices of the operating system and of the compiler are justified. Potential problems with the system, and possible enhancements of it are also described. Tests were performed to verify the correct operation of all of the algorithms used in the calibration of the cameras. Together with the point intersection routines, these tests calculated the position of various control points, the correct coordinates of which were previously known. The calculated point positions are compared to the known coordinates of the points to determine the accuracy of the various algorithms. Further tests were conducted to demonstrate and verify the ability of the system to measure distance in three dimensions. These tests illustrate that the accuracy achievable is approximately 0.053 of the total distance measured for an object occupying 803 of the width of the image. The system improves considerably on the method presently used in South Africa and in many industries worldwide which rely on analytical photogrammetry for the determination of object point locations. While the system suffers from reduced accuracy as a result of the use of digital cameras, this problem will become less important as technology and digital camera resolution improve. Possible enhancements include the use of more numerically efficient algorithms, and the introduction of techniques that would partially automate the identification of control points and pipes.

Modern geodesy utilises advanced space techniques such as VLBI to further the study of crustal motion as well as tidal and rotational deformations of the Earth. One of the parameters in the model used to determine the baseline length between VLBI stations, is the antenna axis offset. This offset is the distance between the secondary axis and the normal projection of the secondary axis onto the primary axis. For a non-intersecting axes antenna mounting, this offset is usually several metres in length. The accuracy of the offset value directly influences the total accuracy of the VLBI results. This work describes how GPS is used to determine the offset and VLBI reference point. Several algorithms for calculating these parameters are investigated and evaluated. Methods are developed to minimise the size and influence of errors. An evaluation and comparison of the results to previous independent determinations of the offset, which use different techniques and instrumentation, clearly show the feasibility of using GPS. This method has the added advantage of allowing the VLBI, SLR and GPS reference frames to be co-located.

Abstract:
There are several surveying methods whose practical function is to determine the areas of land, distances, heights, the amount of earthwork, and to produce reduced images of the earth's surface. The research looks at how geodetic and remote sensing methods can be used, and the results they provide in quarry surveying. The most important in quarry surveying is to get an accurate land surface for calculation of the volume of mineral resources. After quarries surveying, it is possible to calculate the amount of remaining mineral resources. Within the framework of the research, were performed surveying in quarries with geodetic surveying and remote sensing methods. For geodetic surveying was used GNSS receiver and a robotic total station, but from remote sensing methods were used aerial photography and aerial laser scanning. The most important reason why it is important to get an accurate surface and make an accurate volume calculation in quarry surveying is the economic factor. The economic analysis was carried out using a comparison method based on volume, market price and natural resources tax. The research presents the advantages and disadvantages of each surveying method and explains the results obtained, based on economic calculations. The main conclusion is that the accuracy of the preparation of land surface relief models is based mainly on economic calculations because mineral resources are a commodity that is bought and sold for which tax is payable.

Abstract:
The main goal of this study is an analysis of statistical and spatial relationships between land cover, relief and geodetic control points’ location. We aimed at proving the previous results showing that in rural areas the density of horizontal geodetic points depends at least 50% on the land cover. Moreover, two clustering methods, k-means and Kohonen self-organising maps, were used to group surveying districts according to similarity in land use, relief and geodetic control density. The research methods includes statistical methods, ie. Pearson correlation and coefficient of determination computed by Pawlowski method as well as spatial autocorrelation expressed by Moran I global index. The results show that both clustering methods give very similar results, however for the k-means the surveying districts are more spatially clustered, than for Kohonen. The coefficient of determination R2 equals 0.652, what means that geodetic control points density in 65.2% explains by the percentage of built-up areas, forests and the standard deviation of elevation. The analysis was conducted for the 3rd order geodetic control points, for Opoczno district, located in the central part of Poland.

Abstract:
The first stage of any construction is carrying out excavation works. These works are high-priced and timeconsuming. Mostly, for geodetic control of the works, the surveyors are using total stations and GNSS equipment. Last decade, UAV technology was a breakthrough in the geodetic technologies market. One of the possible applications of UAV is the monitoring of excavation works. In the article, the opportunities and accuracy of UAV data while performing the excavation works were studied. The surveying of earth volume in the middle of construction works was made using DJI Phantom 4 UAV. The data were being processed using two photogrammetric software: Agisoft Metashape and PhotoModeler Premium. For comparison, the surveying also was made using a conventional total station. For each data source, the 3D models were generated. The obtained models were compared with each other in CloudCompare software. The comparison revealed the high accuracy of UAV data that satisfies customer’s requirements. For the case of two software comparing, it is better to process data using PhotoModeler. The PhotoModeler software allows performing in-depth data analysis and blunders searching.

Abstract:
The paper presents analysis of determination of vertical movement of the surveying boat called “heave” with the use of Robotized Total Station (RTS) technique. The classical geodetic Total Station was used for sub-centimeter calculation of water level changes during hydroacoustic measurements on the fragment of Vistula river behind the dam and hydropower in Włocławek in Poland. The power station work causes up to 1.7 m movement of vertical reference water surface in aspect of local bathymetric survey. The experimental, hydrographic surveys on the river were conducted where the water level was changing significantly over time depending on the operational schedule of the power plant. Verified hydrographic data had to be brought to the common water level. To determine the final water level, data on the height of the Robotized Total Station prism positioned on the boat during sounding was considered. The RTS technique with 0.02–0.05 m vertical accuracy proved to be very useful and essential in engineering inland bathymetric measurements.

Abstract:
The aim of the modernization is to improve the quality of the collected data. That is necessary especially in those areas where cadastral maps are used in the scale of 1:2880. The most satisfactory results in the process of modernization are obtained on the basis of geodetic field measurements. The aim of the paper is to verify the work related to real estate cadastre modernization in the context of the quality of the cadastral data collected in 1999–2001. This paper presents the results of surveying, which aim was to check whether the data contained in the register of land are a reflection of the facts boundaries and surface parcels. In the analyzes the materials of selected areas from state resources were used. The verification of graphic materials (maps) and descriptive (areas of plots) obtained from the District Office carried out in this paper showed a satisfactory level of data compliance. Factual status on the ground, in most cases, corresponds to the existing in extracts from the land registry, created on the basis of the land and buildings registry modernization in 1999–2001. These data correspond to the areas calculated from the results of the 2016 direct measurements.
