The LAZ file format is a lossless compressed version of the industry-standard LAS format, which is extensively used for storing 3D point cloud data collected by LiDAR (Light Detection and Ranging) systems. LiDAR technology is crucial in fields such as remote sensing, forestry, urban planning, civil engineering, and geographic information systems (GIS) for creating precise digital elevation models and 3D surface models. Because raw LiDAR datasets are exceptionally massive and difficult to transfer or store efficiently, the LAZ format applies advanced compression algorithms to significantly reduce file sizes—often by 80% to 90%—without losing a single bit of the original precision or spatial accuracy. This makes it an indispensable standard for researchers, surveyors, and geospatial professionals who need to manage, share, and process large-scale 3D geographic datasets rapidly and cost-effectively.
