Changes in this Revision: Bugfix in LAStrack Unfortunately there was a bug in LAStrack: The extra_byte output probably was never correct. This bug is fixed now. Also take care about the range of the output values: The extra_bytes parameters without “precise” will cover a maximum range of ~655 meters. See
ArcGIS LAStools toolbox for LiDAR processing In recent days more and more users are discovering the LAStools toolbox that adds powerful LiDAR processing capabilities to ArcGIS versions 9.3, 10.0, 10.2, and 10.2 allowing you to exploit your LiDAR data in the most sophisticated manner through the familiar toolbox interface (see images
This tutorials should help to get an easy start into LAStools. Videos There are a lot of videos about LAStools. This is a list of the most recomended ones. LiDAR processing with LAStools in the Canary islands UNB Fredericton workshop on LiDAR Processing with LAStools LASindex – simple spatial indexing
An open source effort for a vendor-neutral exchange format for geo-referenced full waveform LiDAR called PulseWaves. The format is similar to the ASPRS LAS standard, but instead of storing discrete returns, it stores geo-referenced laser pulses and those parts of the outgoing and returning waveforms that were digitized. The source code
Creates a LiDAR portal for 3D visualization (and optionally also for downloading) of LAS and LAZ files in any modern Web browser using the WebGL Potree from Markus Schuetz. See README file for more information.
This tool flags or removes noise points in LAS/LAZ/BIN/ASCII files. The tool looks for isolated points according to certain criteria that can be modified via ‘-step 3’ and ‘-isolated 3’ as needed. The default for step is 4 and for isolated is 5. It is possible to specify the xy
Finds sufficiently planar patches of LAS/LAZ points fulfilling a number of user-defineable criteria that are output as simple polygons to SHP or RIEGL’s PEF format. The tool was originally designed for generating tie planes to match the point clouds of a mobile scan that suffer from errors in the GPS
Add layer functionality to LAS/LAZ files. See README file for more information.
This is a tool for bare-earth extraction: it classifies LIDAR points into ground points (class = 2) and non-ground points(class = 1). This is a totally redesigned version of lasground that handles complicated terrain much better where there are steep mountains nearby urban areas with many buildings. You can use
This tool classifies, flags, or removes LiDAR points based on their approximate xy distance from polygonal segments. This distance is calculated on a grid with a spacing of 0.5 meters by default. With ‘-step_xy 1.0’ the granularity of this grid can be adjusted up or down. Please license from firstname.lastname@example.org
