What is ZLAS?

What is ZLAS?

A LAS dataset stores reference to one or more LAS files on disk, as well as to additional surface features. A LAS file is an industry-standard binary format for storing airborne lidar data. Optimized LAS (. ZLAS) files are also supported with the LAS dataset.

How do I convert Laz to LAS files?

Procedure

1. Create a new toolbox to create the spatial ETL tool. In Catalog, navigate to a folder or geodatabase to create a new toolbox.
2. In the Generate ETL Tool dialog box, convert the LAZ file to LAS using the created spatial ETL tool.
3. Create a LAS dataset from the LAS file to view in ArcMap.

What file type does lidar use?

The LAS (LASer) format is a file format designed for the interchange and archiving of lidar point cloud data. It is an open, binary format specified by the American Society for Photogrammetry and Remote Sensing (ASPRS). The format is widely used and regarded as an industry standard for lidar data.

How do you uncompress a Laz file?
