SnowEx20 Boise State University Terrestrial Laser Scanner (TLS) Point Cloud, Version 1

This data set contains terrestrial laser scanner (TLS) point cloud data collected as part of the 2020 SnowEx campaign in Grand Mesa, Colorado. Data were collected under both snow-off (September 2019) and snow-on (February 2020) conditions, at both open and forested locations. Multiple scans were conducted at each site and registered together using common targets. Each point contains X, Y, and Z coordinates (Easting, Northing, and Elevation), as well as intensity (i). These TLS data can be used to determine snow depth and explore the interactions between snow and vegetation.本数据集包含2020年SnowEx雪情科考行动在科罗拉多州格兰德梅萨（Grand Mesa）采集的地面激光扫描仪（terrestrial laser scanner, TLS）点云数据。数据采集覆盖无雪（2019年9月）与有雪（2020年2月）两种场景，涵盖开阔点位与森林覆盖区域两类测点。每个测点均开展多次扫描，并通过公共靶标完成多扫描点云的配准。每个点云数据点均包含X、Y、Z坐标（分别对应东向、北向与高程）及强度值（intensity，记为i）。该TLS点云数据可用于反演积雪深度，同时可用于探究积雪与植被间的相互作用机制。
