LAStools

Originally +LAStools was written for airborne #LiDAR. But more and more folks are using LAStools-based workflows for some mobile and terrestrial LiDAR as well as for dealing with the massive point clouds generated by #photogrammetric dense-matching. Here a first tutorial on how to use LAStools with mobile data that was motivated by a customer who wanted to extract a ground model along the rail track bed.

The majority of LAStools users are processing airborne LiDAR. That should not surprise as airborne is by far the most common form of LiDAR in terms of square kilometers covered. The availability of…

Another wonderful open data story in Germany (or maybe we should call it #opendata madness): Also the state of Thüringen, Germany (Thuringia) has just now implemented a revolutionary (by German standards) open geospatial data policy. Not only the #LiDAR data, but everything geospatial is now open via a nice download portal ... (-:

The floodgates of open geospatial data have opened in Germany. Days after reporting about the first state-wide release of open LiDAR, we are happy to follow up with a second wonderful open data sto…

It has finally happened. Now also Germany has "Open LiDAR". At least for one of its sixteen states. I have just downloaded an entire municipality as several ASCII files with #LiDAR point clouds (about 1 GB in two zipped files) ... (-:

Kudos to #OpenNRW
Kudos to OpenNRW for offering online download links for hundreds of Gigabytes of open LiDAR for the entire state of Rhineland-Palatinate (Rheinland-Pfalz) as announced a few months ago: download ra…

First ever LAStools workshop in India (Hyderabad)

We at rapidlasso are finally coming to India. We plan to be in Hyderabad from January 23rd to January 29th, first attending the Geospatial World Forum (GWF), then the FOSS4G-ASIA conference.

On the morning of Thursday, January 26th we'll give a half-day workshop on using LAStools and QGIS at the International Institute of Information Technology, Hyderabad as part of the FOSS4G-ASIA conference ... (-:

After the terrestrial "A R R I V A L" of Leica's US$ 15,990 scanner last week. Will it shake your #LiDAR world? And can we strap that 1 kg 3D scanner (with a range of only 60 meter) that includes full 360 degree imaging onto a UAV or a drone ... ?
Last week Leica Geosystems and Autodesk announced the new BLK360 - an extremely compact and simple-to-use terrestrial LiDAR scanner. The new product will be bundled with Autodesk’s ReCap 360 Pro and a

Big changes are ahead as Germany's geospatial sector awaits the first state-wide release of #opendata that will also include the raw #LiDAR point cloud ...
This is a translation to English of what it states in the amazing announcement that will bring joy, innovation, and progress to a German geospatial community that had been falling behind its European

Our newest "LASmoonie" Rachel will be teaching a course on Remote Sensing for Human Ecology and Archaeology at the University of South Florida. The course will provide students with the practical skills needed to work with contemporary remote sensing data. The course focuses on airborne laser scanning and hyper-spectral data and their application in Human Ecology and Archaeology. Through the course students will be introduced to a number of software packages commonly used to process and interpret these data, with an emphasis on free and/or open source tools. For #LiDAR they will be using +LAStools by +rapidlasso GmbH ... (-:

Downloading Bonn - new tutorial by +rapidlasso GmbH on how to process new Open NRW LiDAR:

Inspired by the availability of open #LiDAR in Germany I am starting a series of small tutorials that looks at how to process this new geospatial data source that OpenNRW has blessed us with. Here is part 1 where we (eventually) try to find the nice plenary chamber of Bonn in the LiDAR where the +FOSS4G 2016 conference was held (as it is now the "World Conference Center Bonn" because many government buildings have moved to Berlin).

http://rapidlasso.com/2017/01/06/nrw-open-lidar-download-compression-viewing/

This is the first part of a series on how to process the newly released open LiDAR data for the entire state of North Rhine-Westphalia that was announced a few days ago. Again, kudos to OpenNRW for…

Assessing Biomass of Shrubberies in Central Croatia for National Inventory Report on Greenhouse Gasses:

To correlate #LiDAR data with biomass volume and test how these correlations vary for different pulse densities, Alen Berta will use three lunatic months of +LAStools to compute various statistics from point clouds matching some of the over 70 field plots with a radius of 12 meters that have been established across more than 550 ha of hilly and lowland shrubberies in Central Croatia. This research aims to assist Croatia in its obligations from the Kyoto Protocol: the creation of a National Inventory Report (NIR) of its green house gasses. One of the most important things for the NIR is to know how many forested areas there are and what their wood stock and increment is.

Generating a DTM in Kyrgyzstan and Tajikistan from dense-matched points of senseFly "eBee" drone imagery.

Stéphane Henriod is the latest participant in our #LASmoons program. He works in Kyrgyzstan and Tajikistan on climate-informed management of ecosystems to maintain their services for the rural population. This includes assessing ecological conditions in the watershed, identifying potential disaster risks, and analyzing glacier dynamics with its response to water runoff. Stéphane uses +LAStools for generating a #DTM from the dense-matched #DSM point grids of +senseFly "eBee" drone imagery that will then be used for identifying risk areas (flood zones, landslides and avalanches, ...).

At INTERGEO 2016 in Hamburg, the guys from Aerowest GmbH shared with us a small photogrammetric point cloud from the city of Soest, Germany that had been generated with the SURE dense-matching software from +nFrames GmbH. We want to test whether - using +LAStools - we can generate a decent #DTM from these points that are essentially a gridded #DSM and not "real" #LiDAR ... (-;

The Canton of Geneva has a cool #opendata policy and a sweet #LiDAR download portal. The disclaimer is a simple checkbox and after accepting the terms you find yourself downloading the fully classified LiDAR of entire Geneva, Switzerland from 2013 with a density of up to 15 pulses per square meter. The pictures show how simple this was. After processing your rectangular area-of-interest the portal will eventually give you a link to a zipped #LAS file (no #LAZ), hence the final download is a bit slow ... (-;

Story
Tagline
efficient tools for LiDAR processing
Introduction
LAStools are a collection of highly-efficient, scriptable tools (optional with GUI) for multi-core batching that process LAS, compressed LAZ, Terrasolid BIN, ESRI Shapefiles, and ASCII in an extremely fast manner:

* lasground.exe extracts bare-earth by classifying ground points
* lasclassify.exe find buildings and the trees above the ground
* lasgrid.exe rasters large LAS files into elevation/intensity grids
* lasboundary.exe extracts an enclosing polygon of the points
* lasheight.exe computes the height of each point above ground
* lasclip.exe clips points against building footprints / flight swaths
* lastile.exe tiles huge amounts of LAS points into square tiles
* txt2las.exe converts LiDAR from ASCII text to binary LAS
* las2txt.exe turns LAS into human-readable easy-to-parse ASCII
* lassplit.exe splits points of LAS files into flight lines
* and more ...

Our powerful, lossless LiDAR compressor laszip.exe turns large LAS files into much smaller LAZ files that are only 7 - 20 percent of the original file size.
