This tool is the “swiss-army knife” of LiDAR file processing. It can convert, filter, transform, subset, repair, scale, translate, zero, clamp, compress, initialize, … LAS or LAZ files in numerous ways. This tool is 100% open source LGPL. For more details see the README file.Continue Reading

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 imagesContinue Reading

Extracts the points from the E57 format and stores them as LAS/LAZ files. This tool reads LiDAR in the E57 format from a *.e57 file and converts it to either standard LAS, compressed LAZ, or simple ASCII TXT. By default all scans contained in the E57 file are merged intoContinue Reading

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.Continue Reading

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 useContinue Reading

Spatial indexing of LiDAR data. Salzburg is a beautiful city in December. The European LiDAR Mapping Forum coincided with the days when the “Krampus” (= “Christmas monsters”) are roaming the Christmas markets in the old town to scare children and adults alike. One gave me a painful whipping in the legsContinue Reading

is almost identical to las2iso except that it can extract elevation contours from much much larger inputs. While las2iso operates in-core and is therefore limited to a maximum of around 20 million points, blast2iso utilizes unique “streaming TIN” technology and can seamlessly process up to 2 billion points. This tool is part of the BLAST extension of LAStools.Continue Reading
