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.
