The long and often undefined period in the post-mining phase challenges geomonitoring with its various responsibilities, like the detection of environmental changes, ground movements and water management. Modern methods of geo- and environmental monitoring observe numerous aspects of these using active and passive sensors with multispectral, hyperspectral and microwave sensors. These offer diverse spatial dimensions and spatiotemporal resolutions from satellites, unmanned aerial vehicles (UAVs) and in situ sensors. Data integration, together with on-site knowledge and experience, provides the basis for comprehensive modeling, which improves the understanding of the environmental changes and their related causes, and is an essential step toward public acceptance. In this article, we aim to give a brief overview of various geo- and environmental monitoring methods.
