Description

The tool allows one to export a point cloud as Cloud Optimized Point Cloud (COPC) LAZ 1.4 file using the "Point Data Abstraction Library" (PDAL). The output file should use the *.copc.laz extension. The number and type of attributes that can be exported depends on the chosen LAS 1.4 point data record format. Please have a look at the ASPRS LAS specification on how these formats are defined.
