- Description
- ASTM E57 is a vendor-neutral binary file format for storing 3D point cloud data, along with associated images and metadata, commonly produced by laser scanners and other 3D imaging systems. It is widely used in surveying, construction, and engineering industries to exchange 3D scan data between different software applications and hardware vendors.
- LAZ is a compressed binary file format for storing lidar point cloud data, serving as a lossless compressed version of the LAS format. It significantly reduces file size while preserving all point data, coordinates, and attributes captured by lidar sensors, making it widely used in surveying, GIS, and remote sensing workflows.
