LAG by arsf

Welcome to LAG

LiDAR Analysis GUI (LAG) is a tool for visualisation, inspection and classification of LiDAR point clouds. It currently supports LAS and ASCII file formats.

LAG was initially created for Airborne Research and Survey Facility - Data analysis Node at Plymouth Marine Laboratory to assist with processing LiDAR data internally, as the project has developed and stabilized we have decided it is ready to release to the public. It is licensed under the GPL, as LiDAR is an evolving technology, and this will enable more parties to openly contribute new ways of handling, processing and analysing LiDAR data.

Features

Two perspectives for visualising points: top-down and profile (from the side)
Support for ASCII and LAS files
Support for UTM and latlong projections with an option to convert between the two
Filtering of points by various criteria
Points classification
Detailed information for selected points
Several visualisation options based on different attributes: height, classification, intensity
Support for multiple flightlines (each file is a separate flightline)
