GRSS Webinar: Airborne Thermal Infrared Hyperspectral Imaging for Mineral Mapping

Alexandrine Huot
Wednesday, January 24, 2018
10:00 AM Pacific Time (6:00 PM GMT/UTC)

Next Tuesday’s speaker is Alexandrine Huot, a Field Application Scientist for Telops, who will demonstrate the benefits of using thermal infrared hyperspectral imaging (TIR HSI) for mineral mapping during an airborne survey, in this case carried out over an open-pit mine in the Thetford Mines (Qc, Canada) area. The results show how the high spectral resolution data provided by the Telops Hyper-Cam airborne system facilitates temperature emissivity separation (TES) and atmospheric correction in order to retrieve a thermodynamic temperature map of the area and its associated spectral emissivity datacube. Mineral mapping of various minerals such as lizardite, serpentinite and quartz was achieved through linear unmixing of the emissivity data using reference emissivity curves found in spectral libraries. The results illustrate the potential of TIR HSI for airborne mapping of silicate minerals. 

The lecture will be broadcast live from Quebec, Canada at 4:00PM GMT/UTC on February 13. (This is 8:00AM February 13, US Eastern Time.)
