OSIRIS, the Scientific Imaging System for Rosetta mission \citep{keller07} has been acquiring images of the nucleus of the comet 67P/Churyumov-Gerasimenko since Aug 2014 with a resolution that allows a detailed analysis of its surface. Indeed, data reveal a complex surface morphology that is likely the expression of different processes affecting the cometary nucleus \citep{thomas15}. In order to characterize these different morphologies and better understand their distribution we performed a geomorphological mapping of the illuminated surface of 67P. For this purpose we used NAC images acquired on August 5-8 with a spatial resolution ranging from 1.5 and 2.4 m/pixel.

Abstract
OSIRIS, the Scientific Imaging System for Rosetta mission \citep{keller07} has been acquiring images of the nucleus of the comet 67P/Churyumov-Gerasimenko since Aug 2014 with a resolution that allows a detailed analysis of its surface. Indeed, data reveal a complex surface morphology that is likely the expression of different processes affecting the cometary nucleus \citep{thomas15}. In order to characterize these different morphologies and better understand their distribution we performed a geomorphological mapping of the illuminated surface of 67P. For this purpose we used NAC images acquired on August 5-8 with a spatial resolution ranging from 1.5 and 2.4 m/pixel.
