Convert ZLAS to LAS

Understanding zlas and las file formats

ZLAS is a compressed version of the LAS file format, developed by Esri for efficient storage and transfer of LiDAR point cloud data. LAS (LASer) is an open, widely used binary format for storing LiDAR data, commonly used in geospatial applications for representing 3D point clouds.

Why convert zlas to las?

While ZLAS offers reduced file sizes, it is a proprietary format and not as universally supported as LAS. Converting to LAS ensures compatibility with a broader range of GIS and point cloud processing software.
