In addition to its main purpose: establishing and maintaining the parameters of the height system for the territory of a given state (country), state levelling networks also serve to establish (register) the contemporary (recent) vertical movements of the Earth's crust. The detection of such movements, besides in a purely research sense, is of great practical importance. The displacement of the benchmarks over time plays an essential role in seismic forecasting in the short and long term. Sometimes, not very often...

The article summarizes the main geodetic activities performed in the region of Southwestern Bulgaria to study the modern crustal movements and clarify the geodynamic situation of the region. The study area is bounded to the north of the southern slopes of the Balkan Mountains, to the south to the southern slopes of the Rila Mountains, to the west - the western border of Bulgaria and to the east - the beginning of the Upper Thracian plain. The area has a complex geological structure with many active faults that mus...

The latest amendments to Ordinance 1 on the creation and maintenance of specialized maps and registers of specialized public state property under the Act on the Black Sea coast spatial development create a procedure for changing and periodically updating these specialized maps and registers, as the existing regulation regulated only their creation and acceptance. The change and the periodic updating of these specialized maps and registers are assigned by the Bulgarian Agency for Geodesy, Cartography and Cadastre t...

The new network of permanent GNSS (Global Navigation Satellite System) stations should be established by the end of this year. At the moment, 18 permanent stations are already established. All stations coordinates must be determined following the conditions dictated by the Republic Geodetic Authority of Serbia, i.e., the Rule Book for establishing the GNSS permanent stations network. The coordinates of stations, the final solution, must be calculated from three consecutive uninterrupted daily sessions as a combine...

The article deals with the developing and applying of the mobile mapping system developed at the Department of Surveying of the Slovak University of Technology in Bratislava. The article presents a low-cost mobile mapping system for simultaneous localization and mapping of the indoor environment. Existing systems are costly and have robust construction and high-power requirements, making them unavailable for some applications. The proposed measuring system consists of three orthogonally placed 2D lidars, a robotic...

In 2004, a digital terrain model (DTM) was created in Serbia. It was obtained by vectorizing isohypses on topographic maps with a scale of 1: 25000. The resolution of the digital model of Serbia is 30 m, and the vertical accuracy, as the authors claim, is 10 m. From December 2021, the global model FABDEM (Forest And Buildings removed Copernicus DEM) is available to the public. It was created based on the data of the Copernicus GLO30 model so that data on forests and buildings were removed from it. Important featur...

The purpose of the paper is to perform a topographic lifting and traction of an architectural project for the execution of a Tyrolean that is arranged on various relief forms, in a hilly area, halfway between Timisoara and Lugoj, Timis County, Romania. The development of an adventure park in an area so close to urban settlements has a great impact on the public of all age categories. Children are the main beneficiaries of such objectives because they test their minds and, at the same time, implement an active and ...

The article presents the current state and views of the author in connection with the creation of a Geoinformation system for the territory of Bulgaria within the meaning of the Geodesy and Cartography Act. The provisions of this law on this issue are from its entry into force, i.e. since 2006 and so far, there is no officially published information on actions in this direction, except for the creation and maintenance of Web applications with information on materials and data from the Bulgarian Geocartfond and inf...

This paper covers the activities of creating a database for the study of modern crustal movements in the region of Sofia and Southwestern Bulgaria, including data from GNSS measurements of the geodynamic network and the results of their processing and analysis, data from permanent stations and archive data from Synthetic-aperture radar, processing and obtaining interferometric images. The local archive of GNSS measurement includes: manual sketches of the location of the points; log sheets of the measurement with i...

The Republic of Bulgaria is located on the periphery of the Eurasian tectonic plate, and part of it falls within the seismically active Aegean extensional region [1]. The study of modern crustal movements is important in terms of elucidating the geodynamic behaviour of the country on a regional and global scale. It should be taken into account when establishing and maintaining geodetic networks for high precision applications. It should be noted that for the main carrier of the Bulgarian geodetic system - the Stat...

The research is part of the -Design of an intelligent system to forecast landslides' processes and their influence on the roads' technical and operational characteristics- project financed by the Ministry of Education and Science of the Republic of Kazakhstan by AP09260066 program. The research goal is in surveying deformed parts of -Almaty-Cosmostation- automobile road nearby critical slopes to identify in the next phases the causes of pavement degradation and formulate then the recommendation to prevent such deg...

Research Object and Relevance. Geotechnical monitoring is an integral part of the safe operation of a facility. When the deformation network is a network of high-rise benchmarks, in addition to vertical displacements, slopes and deflections of intervals are calculated. Often, geotechnical researchers and engineers pay more attention to the quantitative values of various deformation characteristics, comparing calculated values with geomechanical models. In our article, we want to pay attention to the assessment of ...

The theme of the work aimed to present a model of drawing up and carrying out a drawing work for collective constructions in order to build a building with a ground floor + 1st floor + attic. This project has been approved by the City Hall of Timisoara, Romania. The purpose of the work was to identify and execute a topographic elevation, to draw and track the horizontality and verticality of the building for each level (ground floor, floor, attic). The work was completed with the preparation of a cadastral documen...

The structural analysis of the civil infrastructure is vital in order to track the evolution of degradation in time, to prevent disasters, but also to document and conserve the sites of cultural heritage. This paper review-s the workflow on the acquisition of point clouds to Terrestrial Laser Scanner (TLS) with those collected by photogrammetric 3D models based on images captured by an unmanned aerial vehicle (UAV), analyzing the data sets on two diferent type of bridges located in western Romania. The obtained da...
