As if you really needed yet another reason to use open formats for storing your #LiDAR. Either way Howard Butler  - creator of #libLAS  and #PDAL  - has another solid one for you: open formats allow you to write your own readers and writers in JavaScript enabling access to your data within a browser:

Antoine from #Carbomap and Martin from #rapidlasso in front of their rustic, nature-themed joint booth - featuring a dead vegetation layer (wooden garden furniture) as well as a live vegetation layer (plant in a pot) - had a fun event presenting their "organic #LiDAR solutions" together at GeoBusiness 2014 in London ...

At +OpenTopography Facility you can not only download tons of open #LiDAR in our compressed #LASzip format and get large #DTM or #DSM grids rasterized on-the-fly with our "Streaming TIN" technology known as #BLAST. Their servers also distribute the good old #SRTM elevation data with 90m global and 30m US resolution. Have it clipped to your area of interest and download it in your preferred file format (IMG, GeoTIFF, Arc ASCII) ... (-:

PRESS RELEASE, April 1st, 2014, rapidlasso GmbH: 
+Esri and #rapidlasso are announcing to join forces and together develop a #LiDAR  compressor for LAS 1.4 in open source avoiding unnecessary format fragmentation. Their new “LASeasy” tool not only compresses but also optimizes LAS files for efficient area-of-interest queries in the cloud ... (-;

April Fools! But our intention was not (only) to be funny. Most of the article is true. Remember, a "press release" is not a "news report" but a public relation piece written with an agenda. And our "half-true press release" certainly fits that bill. Here the truth behind the half-truth: http://tinyurl.com/truth-in-half-truth

Maybe you have heard of #rapidlasso 's #LASmoons  program for underfunded academics and other #LiDAR  lunatics. (-: Scott Anderson of +University of Colorado Boulder's Institute of Arctic and Alpine Research uses his three lunar +LAStools months to estimate the volume of material transported by debris flows near Boulder, CO in September of 2013 after immense amounts of rain came down.

Whether +LAStools can also create a Digital Terrain Model (#DTM) from those "near-#LiDAR" point clouds as they are output by the dense-matching photogrammetry software from #Agisoft, #Pix4D, or similar is a question we often get asked. Here is the answer ...
Point clouds from dense-matching photogrammetry are popular. Stored in the LAS format - or its compressed LAZ twin - these "near-LiDAR" points are easily ingested into LiDAR processing software to,...

On the last day of our joint workshop at the Forest and Landscape department of the University of Copenhagen, Victor of #Boundless and Martin of #rapidlasso decided on an impromptu, unscripted, and unplanned live experiment in front of the course participants: creating an end-to-end #LiDAR processing pipeline using +LAStools realized as a Processing Model in +QGIS (Quantum GIS ) ...

When #rapidlasso was in Paphos, Cyprus for the RSCy 2014 conference to hold a course on #LiDAR processing with +LAStools, we got a great demo of a drone surveilling an archaeological site during our field trip to the Roman Mosaics. These "drones" are becoming more and more present in everyday life and this is sparking some heated debates, like in Berkeley, California - LAStools' birthplace - where a "drone battle" is coming to the next City Council meeting ...

Open LiDAR downloads via WMS: The Government of La Rioja (Spain) has integrated information about their “open LiDAR” data with a WMS server allowing their users to easily find and download #LiDAR via standard GIS clients (QGIS, gvSIG, ArcGIS …). The LiDAR holdings can also be explored with any modern Web browser through their interactive "GeoVisor" portal ...

Open Like a Venus Flytrap ... ESRI's LAZ clone. ESRI created vendor lock-in controversy in the #LiDAR world with their LAZ clone. Shortly after their proprietary LAS compressor was made available, I did reach out to the #ESRI management team. After all it was Martin Luther King weekend and in MLK's spirit that "We must accept finite disappointment, but never lose infinite hope" I made one final attempt to avoid LiDAR format fragmentation. I suggested to those who had been directing the #LAZ cloning efforts to join forces and jointly develop an open standard for the new LAS 1.4 point types. But as the evil empire instead continues to ramp up their clone production, we shall ready our LiDAR sabers ... (-;

Story

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.
