Spatiotemporal mapping of dust dispersion around mining sites using remote sensing (MinEODust)
Responsible person : Dr. Elsy Ibrahim
Supervisor: Pr. Eric Pirard
Project duration: 1 year (2017 – 2018)
Key words : Copernicus, iron oxide, mining, image processing, multispectral, hyperspectral
MINeoDUST explored the potential of Copernicus data in mine site monitoring making use of Sentinel 2’s proven potential for mapping iron oxides and its high revisiting time. In fact, spaceborne remote sensing shows great potential in mining applications . The advantages of using spaceborne acquisitions are large data coverage and the possible temporal repetition of the acquisition. This allows integrated monitoring at a relatively low cost. When considering the use of freely available data, spatial and spectral resolutions have been limiting, yet, Sentinel-2 shows great potential.
In the scope of this project, an international short course « Earth observation for the raw materials community » was organized in June 2018. It was also hosted at the University of Liège.
MinEODust was also presented:
- in an oral presentation during the Raw Materials week, November 2018 (Brussels).
- in a poster at the Luxembourg Earth Observation day, April 2018.
- in an oral presentation at the Sixth International Conference on Remote Sensing and Geoinformation of Environmentʼ 26-29 March, 2018 – Cyprus.
