This data series contains 142 Light Detection and Ranging (LiDAR) LAS (version 1.2 format) tiles. The data cover an area of the Challis National Forest near Stanley Idaho. The original LiDAR data was collected by Watershed Sciences, Inc. (WS) on August 4th and 5th, 2010. Ground point classification was done using the command-line tool MCC-LIDAR (http://sourceforge.net/apps/trac/mcclidar/) that incorporates a multiscale curvature algorithm. This algorithm requires two variables: a scale parameter and a threshold parameter. For each of the tiles the scale parameter was 0.66667 and the threshold parameter was 0.07.
