Presentation
Full-text available
In geodetic movement and deformation analysis, a novel application of close-range photogrammetry is presented. The achievable accuracy is increased by inserting a geodetic telescope in front of the camera, if necessary. Raspberry Pi computer and Pi camera module is preferred to take photos or videos. Calibration of the non-metric cameras is an impo...

Open-source solutions in geoinformatics have gradually come into the focus of attention over the past decades, becoming of the most well-promising opportunities in tertiary education. It is indubitable that students have to develop their skills to find, apply and contribute to the existing open-source opportunities, besides developing skills regard...

In the recent years, point cloud technologies, such as Unmanned Aerial Vehicles (UAV), Terrestrial Laser Scanners (TLS), Aerial Laser Scanners (ALS), let alone Mobile Mapping Systems (MMS), have come into the focus of attention and have been a subject of considerable public concern in mapping. Thanks to these new techniques, experts can survey larg...

The number of devices equipped with global satellite positioning has exceeded seven billion recently. There are a wide variety of receivers regarding their accuracy and reliability. Low cost, multi-frequency units have been released on the market latterly; however, the number of single-frequency receivers is still significant. Since their measureme...

The quality control, maintenance, and renewal of land registry maps have always been priorities in the surveying profession. Many countries worldwide must face the issue that a significant part of their current digital land registry maps are based on old analogue maps that were digitised without involving any in-situ measurements. A direct conseque...

In geodetic movement and deformation analysis, a novel application of photogrammetry is presented in this article. The resolution of the images is increased by inserting a geodetic telescope in front of the camera. Raspberry Pi computer and camera are used to take photos and videos. Extending the open-source Ulyxes system, image processing was full...

Photogrammetry is experiencing its renaissance in the 21st century. The main driving forces are research in computer vision as well as drone (UAV/UAS/RPAS) technology. There are popular open-source libraries and applications available in these fields (e.g. OpenCV and ODM). In this paper, we report our experiments using OpenCV in specific land surve...

In geoinformatics, there is a considerable demand for dealing with different layers given in different geodetic datums and map projections within the same project. In the majority of the software, the computations are completed on-the-fly using the open-source program PROJ. In recent years, the definition of national reference systems for a wide ra...

The Geological Garden at Tata is an open-air geological museum where a spectacular succession of Tethyan Mesozoic sedimentary rocks, characteristic of the Alpine-Carpathian region, is finely exposed in abandoned quarries and cleaned rock surfaces. In addition to geological values, the area houses copper-age chert mines, the only ones accessible to...

The demand for Global Navigation Satellite System in safety-related applications has rapidly increased in the last few years. The foreseeable release of self-driving cars is already showing the importance of the integrity concept of satellite-based navigations. Correction services as EGNOS can actively improve the integrity assurance build up. The...

Analysis of GNSS-monitoring from the aspects of air navigation-The use of GNSS solutions and the satellite based augmentation system EGNOS (European Geostationary Navigation Overlay Service) can provide a cost-efficient alternative to the standard instrument landing systems applied at airports. The GNSS based approach procedures were designed and p...

System integrity (i.e. the capability of self-monitoring) and the reliability of the positions provided need to be ensured within all safety critical applications of the GPS technology. For the sake of such applications, GPS augmentations, for example Space Based Augmentation Systems (SBAS) are to be applied to achieve the required level of integri...

The use of GNSS solutions and the satellite based augmentation system, EGNOS, the European Geostationary Navigation Overlay Service, can provide a cost-efficient alternative to instrument landing systems at airports. Until the year of 2016, the market uptake of E-GNSS navigation solutions in the Hungarian airspace was hindered by a lack of the rele...

Practical measurements in surveying and geodesy without the GNSStechnique are almost unimaginable nowadays. Application of the GNSStechnique is convenient, efficient and in most of the cases, but not always, accurate enough. However, there are some situations, when applying the GNSS-Technique is not possible due to special circumstances. This paper...

In frame of the tramway network development in Budapest a new tramway line has been established on the south part of Budapest, which crosses the Danube on the Rákóczi-bridge. The bridge superstructure is a continuous double-cell steel box girder having 6 spans with the largest span of 98.52 m. The bridge was originally designed to carry four traffi...

This paper presents a method for constructing local ionosphere models. Processing the data of the International GPS Service's permanent stations, using self developed software, coefficients of models valid for the area of Hungary were determined. Our models describe the Total Electron Content of the ionosphere with 1-2 TECU rms (1 TECU uncertainty...

The EUREF Permanent Network (EPN), established in 1996, consists currently of more than 120 GPS stations from 30 European countries. A significant portion of the network has more than 3 years of observation history, which provides the potential for reliable velocity estimation relevant for geophysical interpretation. This paper addresses the main e...
