Hyperspectral imagery - Mt Ruapehu volcano, New Zealand

This dataset contains an airborne hyperspectral image of Mt Ruapehu, New Zealand. The image was captured by an AISA Fenix pushbroom, full spectrum hyperspectral imaging system, on board of the Cessna 185 aircraft. The survey was taken between 10:25-12:45 NZST on 31 March 2018. The image has been covered to radiance and then surface reflectance using ATCOR4, and then geocoded using PARGE. The individual strips have been co-registered to high-resolution RGB orthophotos captured simultaneously with the hyperspectral data.
