Fusion of photogrammetric and photoclinometric information for high-resolution DEMs from Mars in-orbit imagery

Luo, Bin; Douté, Sylvain; Jiang, Cheng +1 more

High-resolution Digital Elevation Models (DEMs) of the Martian surface are instrumental for studying the red planet. The Mars Orbiter Laser Altimeter (MOLA) instrument onboard the Mars Global Surveyor provided global DEM of high vertical resolution but with a limited spatial resolution that is not enough for characterizing small geological objects…

Automatic detection of Martian dark slope streaks by machine learning using HiRISE images

Di, Kaichang; Wang, Yexin; Xin, Xin +1 more

Dark slope streaks (DSSs) on the Martian surface are one of the active geologic features that can be observed on Mars nowadays. The detection of DSS is a prerequisite for studying its appearance, morphology, and distribution to reveal its underlying geological mechanisms. In addition, increasingly massive amounts of Mars high resolution data are n…
