Last December we visited the Hovermap team at +CSIRO to see their #drone in action and process the #LiDAR point cloud that it produces with +LAStools. This SLAM-based system is mainly developed for autonomous flight and exploration of GPS-denied environments. It is based on the #Puck by +Velodyne Lidar that is cheaper and more light-weight than many other laser scanning systems but also known to produce somewhat “fluffy” surfaces with a thickness of a few centimeters.

We started our visit with a short test flight around the on-site tower. You can download the LiDAR data and the #UAV trajectory of this little demo survey and follow along as we process it step by step:

New Step-by-Step Tutorial: Removing Low Noise from RIEGL’s VUX-1 UAV LiDAR point clouds with LAStools

rapidlasso GmbH recently visited the Blue Carbon team of Dr. Ariel Blanco at the University of the Philippines in Manila to conduct a #workshop on processing high resolution #LiDAR from low-flying drones or helicopters. Test data collected with RIEGL's VUX-1 #UAV near El Nido in Palawan was graciously provided by AB Surveying. As we are allowed to share this data for educational purposes, we wrote up a new step-by-step #tutorial on how to observe and overcome unusual noise and generate a high-resolution Digital Terrain Model or #DTM from the point cloud ...

Sebastian Kasanmascheff is the newest #LASmoons participant. He will perform an object-based classification of conifer trees in Northern Hesse based on high-resolution #LiDAR and multi-spectral orthophotos. As his first step he will delineate the tree crowns and then in a second step perform a semi-automated classification using the spectral signature of the different conifer species.

Two #boats of #CEOs. Background: #Octopus (~ 200 million dollar) of Paul Allen, founder of +Microsoft Corporation. Foreground: #Mono (~ 700 dollar) of Martin Isenburg, founder of +LAStools. Both exploring the waters of Sogod Bay, Padre Burgos, Southern Leyte, Eastern Visayas, Philippines ... (-;

All #LiDAR tiles of the state of Kentucky are now available as #opendata for download in #LASzip-compressed files. Use this online portal to interactively access the #pointclouds tile by tile in the open and compressed #LAZ format by +LAStools ... (-:

Archaeologist tend to be the poorest of scientists. Hence, flying expensive #LiDAR surveys for archaeological research is not something that happens everyday. But when it happens the results are often so stunning that they make it into the headlines of popular news media. How could the idea of a modern day Indiana Jones​ who - equipped with lasers - can literally see through the dense jungles with X-ray-like vision not capture our imagination. The PACUNAM​ LiDAR project mapped around 2000 square kilometers of the Maya Biosphere Reserve​ in Petén, Guatemala, Guatemala​ and their findings are nothing but incredible. Once more we hear of an empire whose cities and infrastructures were much more massive at the time of their peak than archaeologists had previously assumed. This latest survey in Guatemala​ is 100 square kilometers larger than the last massive LiDAR survey carried out solely for archaeological purposes. That project in 2015 by near Angkor Wat​ uncovered in a similar fashion that the full extend of the city of Mahendraparvata on Phnom Kulen​ was much larger than expected. Which ancient civilization's jungle-hidden secrets is LiDAR going to be reveal next ... ?

Luxembourg's #OpenData LiDAR portal uses Potree and LASzip

Kudos for another download portal for #open #geospatial #data. This pilot project realized by Geoportal Luxembourg uses the #potree Web 3D interface for the #pointcloud visualization and exploration of Luxembourg via any modern browser. Free online download of #LiDAR as zipped archives of #LASzip compressed #LAZ files as well as DTMs and DSMs are available via the link below ... (-:

One area that is deeply impacted by #LiDAR is cartography. The sport of orienteering running makes use of thematic maps with lots of fine detail, which demand many hours of field work for the map maker. Our latest participant of #LASmoons will use his 3 lunar cycles of +LAStools to create raster derivatives from LiDAR that help him to reduce the fieldwork. Manuel will process LiDAR flown by Airborne Research Australia to extract features that must be included in the orienteering maps that are going to be used in the 2018 Australian Orienteering Championships ...

Coastal wetlands in Mexico are threatened by conversion to grazing areas, drainage for urban development and pollution. Chris Chandler will use his three lunar cycles of +LAStools to map the current state of these wetlands. He will combine field data, satellite imagery, and #LiDAR. The maps will be made available to local stakeholders including policy makers and land users to aid the development of legislation and financial incentives for local communities to protect these areas.

Processing Drone LiDAR from YellowScan’s Surveyor - a Velodyne Puck based System: We at +rapidlasso GmbH often get asked about which #LiDAR systems are best to be flown on a #drone or #UAV and how to process the #pointclouds they collect. Our latest blog post shows how to deal with some of the challenges of +Velodyne Lidar based systems where surfaces are sampled by a point layer that is often several centimeters "thick". We use data from the #Surveyor system of +YellowScan that was flown above the beautiful Château de Flaugergues in Montpellier during their 2017 LiDAR for Drone conference ... (-:
