Morphological Features-Based Descriptive Index System for Lunar Impact Craters

open access: yesISPRS International Journal of Geo-Information, 2017
Lunar impact craters are important for studying lunar surface morphology because they are the most typical morphological units of the Moon. Impact crater descriptive indices can be used to describe morphological features and thus provide direct evidence ...
