The article presents the results of using multi-zone space survey materials from different spacecraft to distinguish different types of land cover and establish their boundaries and changes in their sizes over time. Space images from Sentinel, Landsat, Proba V, and TERRA/MODIS devices were used, which differ in spatial resolution, rotation frequency, and orbital period. Changes in the sizes of the established types of land cover over time are an indicator that allows assessing the nature and intensity of the impac...

The results of comprehensive ground-space monitoring of geodynamic processes in the area of the former Mirgalimsay deposit (Kentau, Kazakhstan) are presented. The objective of the study is to develop a monitoring and early warning system for hazardous surface deformations under conditions of mine flooding and changes in the hydrogeological regime. Monitoring was carried out using static GNSS measurements (41 benchmarks) and multi-temporal interferometric analysis of archival Sentinel-1 radar images using Persisten...

The paper presents the research methodology of an interdisciplinary project dedicated to the study of the land-sea interaction along the southern part of the Western Black Sea coast. The research area covers the Medni Rid part of the Strandzha coast, which provides favorable conditions for coastal navigation and port activities since ancient times. The project aims to establish the real factors and the regular features in the behavior of local communities in the context of land-sea interaction in the Western Black...

The accurate assessment of a ship-s dynamic behavior is essential for understanding its stability characteristics, particularly in response to free oscillations such as roll decay. This study presents the development and application of a compact, cost-effective inertial measurement system based on the Bosch BMX160 IMU sensor, integrated with a Raspberry Pi 4 single-board computer, for measuring ship model free oscillations both in water and in a controlled air environment. The system enables remote data acquisitio...

The scientific research presented in the article is related to the application of methodologies for monitoring deformations of the Earth's crust. Intensively developing technologies were used, such as GNSS and SAR methods. The Sofia region is among the earthquake zones in Bulgaria. The general conclusion is, that Sofia located in an area characterized by a high seismic risk, with considerable consequences in the case of a strong seismic event. New scientific knowledge about the geodynamics of the region and the ph...

This study examines the morphological characteristics and shoreline dynamics of sandy beaches along the Burgas coast, one of the most diverse and human-impacted regions of the Bulgarian Black Sea. By integrating high-resolution Unmanned Aerial System (UAS) photogrammetry, GIS-based morphometric analysis, and historical shoreline data spanning the 1980s to 2025, the research provides a comprehensive assessment of coastal evolution over the past century. Five representative beaches, Sarafovo, Atanasovska Kosa, Burga...

This study investigates shoreline dynamics and morphodynamic variability along the Kavatsi coastal sector (Southern Bulgarian Black Sea coast) through a multi-temporal analysis spanning the 1980s to 2025. By integrating legacy topographic maps, aerial orthophotos, and recent high-resolution Unmanned Aerial System (UAS) photogrammetry (2020-2025), five representative beach-dune systems were assessed: Kavatsite-North, Kavatsite-South, Smokini-North, Smokini-South, and Camping Veselie Beach. UAS-derived orthophotomos...

The use of remote sensing images in territorial analyses is increasingly used with the development of remote sensing systems. Due to the fact that there are numerous remote sensing systems, both open source and paid, these instruments are widely used in monitoring large areas in order to analyze the dynamics of land use changes. In the present study, an analysis of the ATU Moravita, Timis County, Romania, was carried out based on remote sensing images taken from the Landsat 8 satellite system. Based on the 11 spec...

The submitted paper focuses the issue of using a new technology of Near Infrared Reflectance (NIR) sensors in practice for dosing organic fertilizers based on their composition. The HarvestLab 3000 system was tested in a selected enterprise in terms of its usability in practice. In 2021, an experimental plot was selected in a conventional company situated in the southern part of Czech Republic. The HarvestLab 3000 system with the NIR technology was used for the variable (VR) dosage of digestate as a basic fertiliz...
