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 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...

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 ...

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 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...
