Convert LAS to LAZ

Understanding LAS and LAZ file formats

LAS (LASer) is a file format used for storing LiDAR point cloud data. It is an open and widely adopted format that allows for the exchange of 3D point cloud data between different software applications. LAS files are typically large because they store detailed information about each point, including its coordinates, intensity, and classification.

LAZ is the compressed version of the LAS format. It uses the LASzip compression algorithm to significantly reduce the file size while maintaining the integrity and accuracy of the data. LAZ files are ideal for storage and transfer of large LiDAR datasets as they save space and bandwidth.

How to convert LAS to LAZ

Converting LAS files to LAZ format is a straightforward process that involves compressing the data. This can be done using various software tools that support the LASzip compression algorithm.

Best software for LAS to LAZ conversion

One of the best tools for converting LAS to LAZ is LAStools. It is a collection of highly efficient, open-source tools for processing LiDAR data. To convert LAS to LAZ using LAStools, follow these steps:

• Download and install LAStools from the official website.
• Open the command line interface.
• Use the command: laszip -i input.las -o output.laz to convert your LAS file to LAZ.

Another option is CloudCompare, a 3D point cloud processing software that supports LAS to LAZ conversion. To convert using CloudCompare:

• Open CloudCompare and load your LAS file.
• Go to File → Export and select LAZ as the output format.
