This topic is devoted to all things related to Lidar data visualization, analysis, and editing. I have been developing a tool for the past couple of years. It is documented and can be run from: http://people.eecs.ku.edu/~miller/Wo...dar/index.html. In addition to basic visualization, interactive capabilities include rendering based on (nearly) any per-point attribute in the file, filtering based on the same, spatial filtering based on airspaces and/or (some types of) shapes in an ESRI shape file. Subsets of a lidar file can be saved. Various editing capabilities exist including adding imagery to the points (stored as per-point RGB) and adding LAS codes to the points based on image files or shape files. The documentation at the web site listed above describes these and other capabilities.
There are two programs documented on the site that can be run: one is a World Wind application that displays the point cloud georeferenced on the globe; the other is a standalone application that offers many of the same interactive capabilities. This non-world wind application is useful for at least two reasons: (i) much larger lidar files (and/or much larger subsets of given files) can be displayed, and (ii) many lidar files do not contain information describing their coordinate projections and hence cannot be reliably placed on the globe.
I welcome any and all to try out the applications, share your experiences, and generally participate in a discussion of all things lidar!
