Japan Prefectures, 3D Point Cloud Data

This dataset comprises high-precision 3D point cloud data that covers all prefectures throughout Japan. The data is produced through aerial laser surveys, airborne laser bathymetry, and mobile mapping systems, representing the culmination of many years of dedicated effort. This data will be visualized and analyzed for use in infrastructure maintenance, disaster prevention measures, and autonomous vehicle driving.本数据集包含覆盖日本全境所有都道府县的高精度三维点云数据（3D point cloud data）。该数据集依托航空激光测量、机载激光测深（airborne laser bathymetry）与移动测绘系统（mobile mapping systems）采集生成，凝聚了多年潜心研发的丰硕成果。该数据将通过可视化与分析处理，应用于基础设施运维、防灾减灾及自动驾驶领域。
