High-Precision 3D Point Cloud Data for All Japanese Prefectures

Aerial laser surveys, airborne laser bathymetry, and mobile mapping systems were used to produce this high-precision 3D point cloud data covering all prefectures in Japan. The dataset, published by AIGID under a CC-BY-4.0 license, represents the culmination of many years of dedicated effort. It is hosted on AWS Open Data and is intended for visualization and analysis.

Use Cases

• Planning infrastructure maintenance based on detailed 3D terrain models.
• Modeling disaster prevention measures based on high-precision elevation and surface data.
• Developing autonomous vehicle driving systems based on accurate 3D environmental mapping.

Strengths

• Covers all prefectures throughout Japan.
• Produced through multiple high-precision methods: aerial laser surveys, airborne laser bathymetry, and mobile mapping systems.
• Represents the culmination of many years of dedicated effort.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• Row count and total data size are unknown, which may limit suitability assessment.
