Hayabusa2 ONC Image Bundle Adjustment and Ryugu Color Mosaic Maps

Encompassing GeoTIFF map files and camera geometry information derived from Hayabusa2's Optical Navigation Camera (ONC) images of asteroid Ryugu. It includes mosaics created from the maps and is provided by author Naoyuki Hirata. The dataset was last updated in February 2026.

Use Cases

• Perform photogrammetric analysis using the camera geometry information to reconstruct 3D surface models of Ryugu.
• Create controlled color composite maps from the GeoTIFF mosaic files for geological feature identification.
• Apply bundle adjustment techniques to the ONC image geometry data to refine camera position and orientation estimates.
• Analyze spatial relationships between different map layers in the GeoTIFF files for topographic studies.

Strengths

• Data originates from the Hayabusa2 spacecraft mission, a primary source for Ryugu.
• Includes both processed map products (GeoTIFF mosaics) and raw geometry information.
• Detailed documentation is provided via separate ReadMeFirst and ReadMeSecond files.

Limitations

• The dataset size, row count, and specific file formats are unknown.
• No sample data or column structure is provided to assess data organization.
• The license terms for use and redistribution are unspecified.
