I am looking for a hyperspectral data availability in public domain. Earlier, I use to work with Hyperion data. My group is planning to work for mineral prospecting and radioactive traces prospecting using both ground and remote sensing approach.
As per my knowledge, there is no hyperspectral sensor is operational. Hyperion stopped providing data since 2017, while, AVIRIS is not providing data for all. Only selected PI to have AVIRIS data for a limited location.
I hope the latest geostationary stationary Satellite sensor is launched. in the next few months it will available months for public usage. I have doubts about HYSIS, AVIRIS, and Hyperion for the latest user data. As per my perspective you can use ASTER data with your radiospectrometer to trace the minerals and radio-active materials. Ram
