Assessment of the Environmental Impact of Placer Mining Using Remote Sensing Data
https://doi.org/10.18599/grs.2026.2.17
Abstract
The article examines a methology for calculating the volume of territories with dredge tailings formed as a result of alluvial deposits mining in the Russian Far East, using remote sensing data. The study considers the application of digital elevation models SRTM, ASTER, ALOS, Copernicus, FABDEM and GEDTM. The modified algorithm of Voronoi diagram construction was used for segmentation of territories with dredge dumps, which allows to increase the accuracy of calculations in conditions of considerable length and heterogeneity of relief. A comparative analysis of the result of volume calculation was conducted for two sites – near the village of Briakan (Khabarovsk Krai) and Dzhalinda River (Amur Oblast) – with and without taking into account the height of vegetation cover was carried out.
The study identifies limitations of application of different digital elevation models and ways to improve the accuracy of estimation of the volume of territories with dredge tailings were proposed, which is important both for the assessment of environmental impact and for planning of potential recycling of anthropogenic formations.
