SnowEx20-21 QSI Lidar DEM 3m UTM Grid V001
Listed in NASA Earthdata CMR
Description
This data set is part of the SnowEx 2020 and SnowEx 2021 campaigns and provides bare Earth digital elevation models (DEM) acquired by a scanning lidar system at a 3.0 m spatial resolution, and derived from point cloud digital terrain models. DEMs are available for September 2021 and from multiple areas in Colorado, Idaho, and Utah. These data were produced alongside <a href="doi.org/10.5067/K67GKZQ9WUEI">Vegetation Height</a> and <a href="doi.org/10.5067/4VO7438DP332">Snow Depth</a> data sets.
