Description
The tool allows one to import point cloud data from various file formats using the "Point Data Abstraction Library" (PDAL).
By default, all supported attributes will be imported. Note that the list of attributes supported by the tool is currently based on the attributes defined in the ASPRS LAS specification.
PDAL Version:2.5.0 (git-version: Release)
The following point cloud formats are currently supported:
