ImpactMin will develop new methods and a corresponding toolset for the environmental impact monitoring of mining operations using Earth Observations. Cutting-edge technology will be proposed for the combined use of satellite remote sensing, aerial lightweight measurements and Unmanned Aerial Vehicles (UAVs). The proposed methods will be validated at four demonstration sites corresponding to different scales and scope. The theoretical advancement in science and technology will be made public knowledge with the help of a free multimedia interactive e-learning programme while the tools and foreground knowledge generated by the project will be commercialised by the involved Small and Medium sized companies (SMEs).
