Abstract

This resource contains lidar data, collected at the TW Daniels Experimental Forest (TWDEF) on six separate flights in 2008 and 2009 measuring surface and canopy properties during snow-on and snow-off conditions. It was collected for the purposes of obtaining a digital elevation model (DEM) to characterize the area for snowmelt modeling, and by differencing between snow-on and snow-off observations to characterize the spatial distribution of snow depth. Canopy lidar returns also characterize the vegetation. The data was collected by the Utah State University (USU) Lidar-Assisted Stereo Imaging (LASSI) laboratory. The data was initially processed at USU shortly after collection and additionally processed by the Space Dynamics Laboratory (SDL) in support of iUtah lidar efforts in 2016.

The metadata report (sdl16-1363-.pdf) gives details about the hardware used for data collection, the flight plans and resulting data, the data processing steps, and a brief error analysis.

Zip files are named by the collection date and contain:
- Terra Scan Binary Files
- LAS Files (one for each flight line and the combined file)
- KML Files (one for each flight line)
- ASC DEM file (1 m resolution)
- PNG Hillshade file
A complete list can be found on pp. 17-22 of the metadata report.
