“…The evaluation of the quality of preliminary data, in the case of temporal-spatial multispectral analyses, applies among others to satellite imagery of space missions of NASA (Landsat) and ESA (Copernicus). Pawlik et al [17,18] point out possible criteria for their evaluation, among which can be distinguished: time series, survey area, spatial resolution, and spectral resolution. Understanding the different spectral ranges of satellites allows calculations of vegetation indices, which play a key role in observing post-mining processes [17,19].…”

The operation of a mining facility provides a wealth of data, starting from mining licenses, documentation of extracted deposits, tunnel reinforcement methods, to documentation regarding the termination of mining operations, which impacts the natural environment at the local, regional, and supra-regional levels. The results of projects conducted by the Research Center of Post-Mining at the Technical University of Georg Agricola in Bochum present the possibilities of integrating environmental geo-monitoring methods to understand the processes occurring both during and after mining operations. Among the research methods used, spatiotemporal multispectral analyses of satellite imagery and images from drone flights stand out, and these will be presented in this paper. Additionally, in-situ measurements using soil sensors, weather stations, the application of mobile GIS, and three-dimensional modelling of geological structures should be noted. A key aspect of mining process research is the implementation and integration of all available geospatial data, allowing the consideration of post-mining processes as a cycle of interconnected, independent values that, through data analysis and validation, enable a comprehensive understanding.

Mobile GIS allows users who work in the field to acquire, edit, update, store, display and analyse data. It combines modern technologies such as mobile devices (tablet, smartphone), software (applications in Android and iOS), location of a point / place using GNSS transmitter and providing wireless connectivity via the internet. An important step in any scientific research should be the verification of the obtained results, which can be done by using a modern tool such as mobile GIS. In this article the characteristics of mobile GIS will be presented as well as selected examples of modern research carried out at universities in Germany: Technische Hochschule Georg Agricola University (THGA), Technical University Bergakademie Freiberg (TUBAF) and Poland – Wrocław University of Science and Technology (WUST).

“…The European Ground Motion Service [24] has played a pivotal role in advancing the accessibility of Sentinel-1 data, thereby integrating radar images into standard monitoring routines for land subsidence. Specifically, it has facilitated the examination and analysis of land subsidence processes across various mining regions worldwide, including Belgium [25,26], Colombia [27], China [28,29], the Czech Republic [30], the United Kingdom [27,31], the Netherlands [32], Germany [19,20,27,31,[33][34][35], Poland [36][37][38], and the Republic of South Africa [31]. The complexity of post-mining processes has been addressed through the application of innovative and cutting-edge research methods and instruments in recent decades.…”

Direct and indirect effects after mine operations cease operating must ideally be subjected to perpetual monitoring routines in order to detect possible risks or avoid adverse effects on the surrounding ecosystems at an early stage. In this contribution, mining subsidence lakes created inside the nature reserve Kirchheller Heide and Hilsfeld Forest are subjected to analysis for a long-term monitoring scheme. For this purpose, we employ high-resolution unmanned aerial system (UAS)-based multispectral and thermal mapping tools to provide a fast, non-invasive and multitemporal environmental monitoring method. Specifically, we propose to monitor vegetation evolution through multispectral analysis, biotypes identification using machine learning algorithms, and water surface extent detection, together with their thermal behavior. The aim of this contribution is to present the proposed workflow and first results to establish a baseline for future analyses and subsequent surveys for long-term multi-temporal monitoring.
