This article is obsolete now. Please see the new article about „LAStools@linux“. LAStools@linux multicore is now available as a beta version. The data quality is checked against the current version of LAStools – we assume that the data is valid. Some arguments don´t currently work with Linux multicore, so this beta/test version was released for […]

With the latest release of LAStools (230731) we are introducing two new tools:

LAS and LAZ are both very common and powerful formats to save pointcloud data. Nevertheless, some users, or programs, may require another point data format. A common general format to save geometric data, for said requirement, is the wavefront OBJ format. Using one of the sample LAZ files of LAStools we will show you how

This tool corrects the intensity attenuation due to atmospheric absorption. Because the light has to travel longer distances for points with large scan angles, these points may be detected with reduced intensities. In order to get a reliant attenuation estimate several parameters are essential: As the absorption coefficient may be difficult to grasp, lasintensity implements
As an input take, for example, a LAS/LAZ/TXT file and a SHP/TXT file with oneor many polylines (e.g. powerlines).This feature modifies points within a certain distance of those polylines.There are two separate options for running point selection; you can either: Affected points can be classified, clipped, or flaged. The input SHP/TXT file must contain clean
Until now LAStools have 2 tools to modify lidar data using shapefiles: las3dpoly covers the missing z dimension. This enables the user to modify points along a 3D-corridor within a LiDAR data file. One possible use for this feature is classifying powerlines. Below you will find an example of how to classify powerlines: The sample
