This article is devoted to the analysis of the consequences of military actions using the integration of spectral indices and remote sensing to assess the affected areas. Military conflicts have significant impacts on the natural and human environment, and accurately quantifying the extent of damage is an important task for recovery and humanitarian assistance. This paper examines the role of spectral indices such as the Normalized Difference Vegetation Index (NDVI), the Enhanced Vegetation Index (EVI), and the No...

In this study the effect of hazardous geodynamic processes in the area around the city of Sofia is investigated using radar satellite data. The area is of particular interest due to its high population density and high concentration of industrial facilities and residential areas. This highlights the importance of the study area in societal aspect. This the reason the authors set the main objective of this research to be the monitoring of the ongoing geodynamic processes by complementary use of synthetic aperture r...

The article considers the intensity of the subsidence process of the given surface of the territory of the Central coal-mining district of Donbas from 2015 to 2021, according to radar data from the Sentinel-1 satellite. There are 26 mines on this territory, most liquidated by completely uncontrolled flooding of mining operations without further control of the hydrodynamic regime. This study aims to determine the dangerous zones formed due to soil subsidence to rank the territory, particularly minefields, according...

The escalating intensity of climate change-induced storms necessitates efficient methods for surveying storm-damaged forests. This study conducted in Estonia employed Unmanned Aerial Vehicles (UAVs), equipped with compact cameras, to assess damage over a 16 square kilometer storm-affected area. We created digital surface models (DSMs) and orthophoto mosaics using two types of drones - a fixedwing and a multirotor. While both types had their distinct advantages depending on the terrain, a 70% x 70% overlap of image...

The presented paper deals with the targeted application of pre-emergent herbicides. The field experiment was established in 2022 and 2023; two plots sized 26 ha and 30 ha were selected and the accuracy of the application was tested. There were local outbreaks of weeds on selected plots of land, which had to be eliminated before sowing the main crop - soybeans. Both plots were monitored using an unmanned aerial vehicle (UAV) - Mavic 3M with the multispectral camera. After the end of the monitoring, spectral analysi...
