Hyperspectral classification reference toolkit

Martian Cap : Hyperspectral Classification Reference

This toolkit is available upon request. Please contact Frédéric Schmidt.

Introduction

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).
