The Visible InfraRed Thermal Imaging Spectrometer, VIRTIS onboard ESA’s Rosetta
mission has completed two extensive mapping campaigns of the 67P/Churyumov-Gerasimenko comet
nucleus in August-September 2014. After calibration
and geometrical projection on nucleus shape model,
VIRTIS data were processed to retrieve the distribution
of several spectral indicators (spectral slopes, organic
material band depths) from which compositional maps
are built. Apart from being appropriate to map surface
composition, those indicators allow us to correlate
them with local morphological features (patches, boulders, scarps, terraces, active areas) and thermal properties
