Qualitative relational mapping and navigation for planetary rovers [PDF]

Robotics and Autonomous Systems, 2016
This paper presents a novel method for qualitative mapping of large scale spaces. The proposed framework makes use of a graphical representation of the world in order to build a map consisting of qualitative constraints on the geometric relationships between landmark triplets.

Geology of the Kuiper quadrangle (H06), Mercury

Journal of Maps, 2022
The Kuiper quadrangle (H06) is located at the equatorial zone of Mercury and encompasses the area between 288°E – 360°E and 22.5°N – 22.5°S. Using the NASA MESSENGER data, we compiled a geological map of the quadrangle at a 1:3,000,000 scale. The mapping
