Ecological restoration and calculation of revegetation percentage made by drone
Ecological restoration: results obtained from 1187 aerial images taken by Tech Drone Service company. Post-processing and data analysis by Drones Imaging.
Calculation of revegetation percentage on a two acres old mining site between 2020 and 2022
Ecosystem analysis and monitoring service carried out as part of a pilot project for the restoration of biodiversity on a former mining site.
With this commercial use case and thanks to a recurring drone flight each year, a calculation of the revegetation percentage make it possible to precisely monitor the level of plantations development season after season. Eventually, ecological restoration, also called revegetation, will allow the repair of the ecosystem destroyed by industrial activity. It will also limit the invasion of unwanted plants and limit soil erosion.
According to a study by the United Nations Environment Programme, 40% of the world economy depends on the proper functioning of ecosystems. Their preservation and restoration are therefore a necessity and are part of France’s political commitments, in particular via the national strategy for biodiversity 2011-2020.
