Three Videos from Full Day Workshop on LiDAR at IIST Trivandrum in India

Three videos from a full day workshop on LiDAR processing at the Department of Earth and Space Sciences of the Indian Institute of Space Science and Technology (IIST) in Thiruvananthapuram, Kerala, India held in October 2017 that was organized by Dr. A. M. Ramiya who we thank very much for the invitation and for being such a kind host. After our usual introduction to LiDAR and LAStools we use three raw flightlines from Ayutthaya, Thailand as example data to perform a complete LiDAR workflow including

  1. LiDAR quality checking such as pulse density, coverage, and flightline alignment
  2. LiDAR preparation (compressing, tiling, denoising, classifying)
  3. LiDAR derivative creation (DTM and DSM rasters, contours, building and vegetation footprints)

You can download the three flightlines used in the tutorial here (line2, line3, line4) to follow along.

ultimate video hands-on for LiDAR with LAStools

An easy-to-follow video tutorial on LiDAR processing with LAStools recorded in two parts (1, 2) in Baja California on April 8th 2015 as part of a 3 day workshop at CICESE in Ensenada. It includes a presentation but is mostly a hands-on that you can follow after downloading LAStools. For the first part skip to the 45th minute (or use this direct link):

It introduces LiDAR processing with examples of different projects such as flood mapping in the Philippines, canopy modeling in the Canary Islands, conflict-archaeology in Polish forests, and other laser adventures. This is followed by a hands-on of the core steps of LiDAR processing using LAStools: (1) LiDAR quality checking, (2) LiDAR preparation (tiling, classifying, cleaning), (3) manual editing of LiDAR files, (4) LiDAR derivative creation (DTM/DSM/…). These steps are repeated in more depth in the second part:

The second part ends with a detailed exploration of full waveform data in PulseWaves format after 3 hours and 9 minutes (or use this direct link). Here a summary of the entire 3 day event provided by OpenTopography. We are very grateful to Dr. Alejandro Hinosa for organizing this amazing event and the sponsorship by CONACyT and CICESE.

First LAStools Workshop in Latin America

PRESS RELEASE (for immediate release)
March 9, 2015
rapidlasso GmbH, Gilching, Germany

The week after Easter is poised to see Latin America’s premier LiDAR event of 2015 when LAStools, CloudCompare, and OpenTopography converge for the 3 day NPAC 2015 workshop in CICESE in Mexico. Just across the US border (one hour South of Tijuana) lies the coastal town of Ensenada in Baja California where Dr. Alejandro Hinojosa has done magic to bring together (for the first time) a dynamic group of well-known LiDAR enthusiasts.

The action-packed event runs from April 8th to 10th and includes a full-day course on LiDAR with LAStools by Dr. Martin Isenburg of rapidlasso GmbH, a full-day tutorial on processing point clouds with CloudCompare by its creator Dr. Daniel Girardeau-Montaut, and a day of exciting talks on data portals, landslide detection, commerical drones, structure from motion, and much more. The NPAC 2015 workshop is open to all and registration is free thanks to sponsorship by CONACyT and CICESE. The main language of the workshop will be English.

First ever LiDAR Processing Model in QGIS using LAStools

We at rapidlasso had finally the chance to meet Victor Olaya of Boundless who created the Processing framework (formerly know as Sextante) that is now integral part of QGIS. On the last day of the joint workshop organized by Dr. Lene Fischer at the Forest and Landscape department of the University of Copenhagen that saw 2 days of LiDAR processing with LAStools followed by 2 days of GIS exercises with QGIS and Processing, we decided to do an impromptu, unscripted, and unplanned experiment in front of the course participants, doing something none of us had tested before:

We wanted to see if we would be able to use the existing LAStools and QGIS Processing functionalities to create a LiDAR Processing Model that would take a single LAZ or LAS file as input, find the bare-earth points with lasground, compute the height of each point above the ground with lasheight, look in the remaining points for buildings and vegetation with lasclassify, generate a set of polygons around the building points with lasboundary, and open the resulting shapefile in QGIS.

After some discussion a Processing Model was decided upon. Holding our breath we started it. SUCCESS! On the first try! It was a nice way to conclude our 4 days of LAStools and QGIS training as you see below … (-:

See this blog entry (also see the blog’s comment section) for information on how to add LAStools to your QGIS Processing toolboxes.

workshop at UNB Fredericton: LiDAR Processing with LAStools

After attending Silvilaser 2012 in Vancouver and giving a keynote on “The Story of LAStools”, I had a stop over in Halifax and drove a cute little Fiat 500 convertible on a perfect Indian summer fall day to UNB Fredericton where Patrick Adda had organized a half-day workshop on LiDAR Processing with LAStools. Here is the first 54 minutes of my talk all the way through to LiDAR quality checking with LAStools. Special thanks to Houman for filming and to Patrick for editing the video.

LiDAR processing with LAStools in the Canary islands

On my way to the FunGIS LiDAR workshop in Cairns,  I stopped in Adelaide to visit Airborne Research Australia. Flinders University recorded my talk on the capabilities for LiDAR processing with LAStools. In this introduction I use a recent project in the Canary islands, Spain, in Spring of 2012 as the example. We created canopy height maps, forest density grids with LAStools and showed that the LiDAR already owned by the municipal government agency could be used to significantly improve their photogrammetrically derived DTMs.
