Monitoring opencast mine restorations using Unmanned Aerial System (UAS) imagery
Open-pit mine is still an unavoidable activity but can become unsustainable without the restoration of degraded sites.
Monitoring the restoration after extractive activities is a legal requirement for mine companies and public administrations in many countries, involving financial provisions for environmental liabilities. The objective of this contribution is to present a rigorous, low-cost and easy-to-use application of Unmanned Aerial Systems (UAS) for supporting opencast mining and restoration monitoring, complementing the inspections with very high (<10 cm) spatial resolution multispectral imagery, and improving any restoration documentation with detailed land cover maps.
