Please Note: The LAS files included in downloaded items have been compressed using LASzip. LASzip is an open-source, lossless compression for LiDAR point-cloud data in the LAS format that provides significant file size reductions. To uncompressed the .laz files in your download package, you can download the latest version from laszip.org or download the tool (for Windows) directly: laszip.exe
