Moon LRO LROC NAC Boulder Database v1 Watkins
The Lunar Boulder Database contains boulder distributions around small (< 1 km), young (< 200 Ma) lunar impact craters located near spacecraft landing sites. Boulders were manually identified and measured on images from the Lunar Reconnaissance Orbiter (LRO) with the Lunar Reconnaissance Orbiter Camera (LROC) Narrow Angle Camera (NAC; Robinson et al., 2010) at scales of ~0.5-2 m/pixel. LROC NAC images allow for boulders ~1-2m in size and larger to be identified and measured.
These boulder distributions are being used to understand boulder degradation rates on the lunar surface, and to assess landing site hazards for future surface missions to the Moon. This dataset is being archived in the Planetary Data System (PDS) for use in future boulder distribution and landing hazard studies. Future boulder counts and any refinements to existing measurements will be uploaded into subsequent versions of this dataset.
This archive uses PDS4 archiving standards. An overview of PDS4 is provided in the PDS4 Concepts document (2018) and the standards are specified in the PDS4 Standards Reference (2018).

General
- Purpose
Created as part of a project funded by NASA’S Lunar Data Analysis Program (LDAP), the purpose of this dataset is to provide locations and diameters of boulders around small, young impact craters on the Moon. These boulder counts were conducted as part of a study aimed at determining regolith production rates and assessing landing site hazards, as discussed in the associated publications. Researchers are encouraged to read the publications and data description document to understand how the data was acquired and used.
