What is a LAZ file?
LAS files contain data about the Earth's surface, recorded using Light Detection and Ranging (LIDAR) technology. Because these files contain a large amount of data, scientists often find it useful to compress the files for more efficient storage and to make them easier to share with others.
LASzip is a tool scientists can use to compress LAS files. It is included in the LAStools LIDAR data processing toolkit. When a scientist uses LASzip to compress a LAS file, LASzip saves the compressed version of the file as a LAZ file.
How to open a LAZ file
You can decompress a LAZ file with LASzip, a tool included in the LAStools toolkit. LAStools is available for Windows and Linux.
