SnowEx20-21 QSI Lidar DEM 0.5m UTM Grid, Version 1

This data set is part of the SnowEx 2021 campaign and provides bare Earth digital elevation models (DEM) acquired by a scanning lidar system at a 0.5 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 Vegetation Height and Snow Depth data sets.

本数据集隶属于雪实验（SnowEx）2021野外考察计划，包含由扫描式激光雷达系统以0.5米空间分辨率获取、基于点云数字地形模型生成的裸地数字高程模型（Digital Elevation Model, DEM）。该数据集涵盖2021年9月科罗拉多州、爱达荷州与犹他州多个区域的相关数据，且与植被高度及雪深数据集同步生成。
