A GIS-based spatial data structure for integrating multi-resolution terrain data from lunar orbiter and rover: Application to Lunar Rover Path Planning and Operation

초록

The discovery of rare resources and water-ice has led to a surge in rover-centric lunar exploration missions. While GIS-based spatial data structures have been widely used to support lunar missions, they have limitations in integrating global low-resolution terrain data from lunar orbiters with local high-precision 3D data from rovers. This study proposes a new network model that integrates a quadtree with an 8-direction network. The network model supports unmanned rover exploration by integrating terrain data and generating a high-resolution DEM of the exploration area. The proposed model was validated on a simulated lunar terrain, confirming its ability to generate a safe driving path and a high-resolution DEM. © ACRS 2025.All rights reserved.
