BRIEF DESCRIPTION OF THE METHODOLOGY TO BE USED TO ADDRESS THE SCIENCE GOALS AND OBJECTIVES: AS SOURCE DATA FOR DETRENDED TOPOGRAPHIC MAPS WE WILL USE THE PDS-RELEASED DATA SET SLDEM2015 THAT COMBINES THE HIGH-PRECISION TOPOGRAPHIC DATA FROM LOLA AND HIGHRESOLUTION TOPOGRAPHIC DATA DERIVED FROM KAGUYA TC STEREO CAMERA IN THE FORM OF GLOBAL RASTER TOPOGRAPHIC MAPS. THE DETRENDED ELEVATION FOR EACH PIXEL WILL BE CALCULATED AS A DIFFERENCE BETWEEN ITS ACTUAL ELEVATION AND THE MEDIAN ELEVATION OF ALL PIXELS WITHIN A CIRCULAR WINDOW CENTERED AT THIS PIXEL. THE DETRENDED TOPOGRAPHY WILL BE CALCULATED AS A DIFFERENCE BETWEEN ACTUAL TOPOGRAPHY AND A TREND SURFACE DEFINED AS A MEDIAN TOPOGRAPHY IN A CIRCULAR SLIDING WINDOW.
