Geographic Information Systems Stack Exchange is a question and answer site for cartographers, geographers and GIS professionals. It's 100% free, no registration required.

Is there an easy path to visualizing this LIDAR data? I have QGIS, and some USGS LIDAR data in (.las) format downloaded from http://lidar.cr.usgs.gov/ . This means I have both the (.las) and metadata in (.xml) format.

I am aware liblas, but not how to apply it to this task. I am running on Ubuntu 11.04 with QGIS 1.7.0-Wroclaw. Presumably GRASS is available to me as well.

A similar question for ArcGIS is How to convert LAS to GRID/Raster for ArcGIS input? . I just need to get a sense of this data and the registration... conversion to a DEM would be OK if I can visualize it.

The lasview.exe tool (README) that Bryce mentioned has a shorter LAStools.org URL now ... (-:

rapidlasso.com/2013/09/30/… there appears to be new progress on integration of LASTools and QGIS. –  wildintellect Oct 11 '13 at 1:52

GRASS has a documentation section on LiDAR in their wiki. Give it a read; you can use libLAS to import into GRASS, and then use many of the GRASS tools once it's in there.

Is there anything more digested or step-by-step? There are a lot of gaps to bridge there... –  Bryce Jan 27 '12 at 1:53
    
So far I'm having some good results with lasview.exe from cs.unc.edu/~isenburg/lastools , which is at least letting me verify the data is reasonably good. –  Bryce Jan 27 '12 at 2:03
    
GRASS 7 is offering v.in.lidar: grass.osgeo.org/grass70/manuals/html70_user/v.in.lidar.html –  markusN Jan 27 '12 at 16:07
    
Hi Bryce, I don't know of anything more 'digested' and am far from a LiDAR expert. I suspect you should be able to piece some of that stuff together and at least get started, learning the rest as you go. –  Darren Cope Jan 27 '12 at 19:13

Lastools are a great candidate to be added to the QGIS processing framework. Anyone interested in supporting its implementation? –  Giovanni Manghi Feb 13 '12 at 14:09
