Cloud Optimized Point Cloud (COPC) is a LAZ-based file format that arranges lidar point clouds so that only the needed parts can be read with HTTP range requests. It stores octree hierarchy information inside LAZ 1.4 variable length records, so chunks can be located by spatial region or level of detail, and data can be visualized or analyzed directly from cloud storage without downloading the whole file. It follows the same idea as Cloud Optimized GeoTIFF in the raster field, and ordinary LAZ readers can still open it as is.
Geospatial, compressed, range-readable, LAZ-compatible point cloud format.
