CASUS Institute Seminar, Dr. Rupsa Chakraborty, postdoctoral researcher, Center for Advanced Systems Understanding CASUS & Helmholtz-Institute Freiberg for Resource Technology HIF, Helmholtz-Zentrum Dresden-Rossendorf (HZDR)

Abstract of the talk// Discovering mineral resources that fuel the green energy transition requires innovative, robust, and accurate remote sensing datasets for regional-scale mineralogical assessment. The new generation of satellite-based hyperspectral data could help provide this by allowing the identification of subtle mineralogical changes over large areas along with repeated temporal data for efficient monitoring. Although mineral systems usually have large spatial footprints, they are often difficult to detect from satellites due to their subtle spectral manifestation, and overlying vegetation and topsoil reducing the effective pixel area. On the contrary, airborne or uncrewed aerial vehicle (UAV)-based hyperspectral data can provide finer spatial resolution, potentially capturing more spectrally complex information than spaceborne hyperspectral data, but over smaller areas and at a relatively higher expense. Thus balanced integration of the airborne/UAV and the spaceborne hyperspectral data can address many current gaps in the mineral prospecting and monitoring domain.

CV// Rupsa holds a B.Sc. in Geology from Burdwan University and an M.Sc. in Applied Geology from the Indian Institute of Engineering, Science, and Technology (IIEST), Shibpur, India. She continued her education with a Post Graduate Diploma in remote sensing, specializing in earth sciences, from the Indian Institute of Remote Sensing (IIRS-ISRO), Dehradun, India. During her time at IIRS-ISRO, she worked as a research fellow in the Department of Geosciences. Subsequently, Rupsa embarked on a Ph.D. journey at Massey University, New Zealand, where she focused on the use of hyperspectral remote sensing to explore surface multidisciplinary indicators for subsurface mineral exploration. She is currently working as a postdoctoral researcher, employed by CASUS, at HIF in Freiberg (both institutes of the HZDR). Her work revolves around mineral mapping using hyperspectral data on various platforms, including UAV, airborne and satellite-based platforms.

Rupsa will be talking live in Görlitz. However, as the event is organized in a hybrid format that includes a videoconferencing tool by Zoom Inc., people interested in the topic have the chance to also join the talk remotely. Please ask for the login details via
