LAStools: converting, filtering, viewing, processing, and compressing LIDAR data in LAS format. Download LAStools HERE now with GUIs and ArcGIS toolbox abstract: We provide an easy-to-use, ultra-light-weight, very efficient C++ programming API called LASlib (with LASzip DLL) that implements reading and writing of LiDAR points from and to the ASPRS LAS format (version 1.0-1.3) as well as its --- losslessly compressed, but otherwise identical twin --- the LAZ format (see below).
All source code (LGPL) is included. Built upon LASlib (with LASzip DLL) are LAStools - a collection of highly-efficient, scriptable tools with multi-core batching that process LAS, compressed LAZ, Terrasolid BIN, ESRI Shapefiles, and ASCII. The program lastile.exe creates a tiling of LAS/LAZ files, lassort.exe z-orders them, and lasclip.exe clips away points falling into polygonal shapes (e.g. building footprints). How to install LAStools toolbox in QGIS. The more complex installation instructions are only relevant for older QGIS versions.
Starting with QGIS 2.10 or newer you can skip directly to step 4 and disregard most of step 6: We had an ArcGIS LiDAR processing toolbox since April 2012 and now we have one for QGIS as well. Rapidlasso GmbH. Our flagship product is the LAStools software suite, which is an easy download (28 MB) and is available for licensing (see pricing).
It is a collection of highly efficient, batch-scriptable, multicore command line tools. We have tools to classify, tile, convert, filter, raster, triangulate, contour, clip, and polygonize LiDAR data (to name just a few functions). All of the tools can also be run via a native GUI and are available as a LiDAR processing toolboxes for ArcGIS versions 9.3, 10.0, 10.1, 10.2, or 10.3, for QGIS versions 1.8, 2.0, 2.2, 2.4, 2.6, 2.8, or 2.10, and for ERDAS IMAGINE versions 14.0 and 15.1.

Please see the Autodesk Creative Commons FAQ for more information. Introduction To UAV Photogrammetry And Lidar Mapping Basics. UAV lidar and photogrammetry imaging applications are increasing rapidly.
This is not surprising as using GPS enabled UAVs for aerial surveying is very cost effective in comparison to hiring an aircraft with photogrammetry equipment. Because UAVs are relatively inexpensive, many organisations will have their own fleet, allowing for rapid surveys over large land areas where required. With GPS-equipped drones, digital cameras and powerful computers, surveys with an accuracy down to 1 to 2 cm is very possible. In this post we take an overall look at this technology and the sectors benefiting from using UAVs for photogrammetry and lidar mapping. We also discuss the drones on the market and the compatible software. Dem - Viewing LIDAR data (.las) in QGIS?
