Analysis of changes of the vegetation condition on the area of the closed Prosper Haniel mine using multispectral satellite and drone images.

Mining and post-mining processes have a significant impact on the environment. An important current task and challenge is therefore the continuous monitoring of mining areas. The project "Digital Twin - Integrated Geomonitoring" financed by RAG Stiftung (no. 20-0013) and carried out in cooperation with the Geological Survey of North-Rhine Westphalia develops an integrated geoscientific workflow to monitor the former mine Prosper-Haniel, (Bottrop). This paper describes a method of environmental geo-monitoring using vegetation indices, which allow long-term, temporal-spatial observation of changes and trends at the land surface. The freely available EU-Copernicus Data with its multispectral Sentinel-2 as well as the NASA Landsat-8 data provide a giant data repository for this investigation. To validate the results a subsurface model of the overburden und tectonic elements of the mine is integrated. The results show the full valorisation of integrated geoscientic workflows to understand changes at the surface above a former mine.
