title: Martian South Polar Cap: Hyperspectral Classification Reference

description: This kit contains a classified reference hyperspectral image from the OMEGA instrument (Bibring, J.P., et al., 2004) observing the South Polar Cap of Mars in January 2004. Without any available ground truth, the classification using the WAVANGLET method (Schmidt, F., et al, 2007) is used as a reference and has been confirmed by several other studies such blind source separation (Moussaoui, S., et al., 2008) and physical radiative transfer inversion (Douté, S. , et al., 2007 ; Bernard-Michel, C., 2009). CONTENT ORB0041_1_V03.REF: OMEGA hyperspectral cube binary data. This cube is calibrated and express in radiance factor (Radiance/cos(incidence)) and contain atmospheric contribution of aerosols and CO2 gas.
