Airborne Laser Scanning (ALS) Point Clouds of Trail Valley Creek, NWT, Canada (2016)@en

The airborne laser scanning (ALS) datasets were acquired at the Arctic tundra site of Trail Valley Creek (TVC), Northwest Territories, Canada, which is underlain by continuous permafrost. Basic processing and filtering steps were applied to the ALS point cloud. Based on a classification into ground and vegetation points, a Digital Terrain Model (DTM) and rasters of mean and maximum vegetation heights are derived. Detailed metadata are included.

本机载激光扫描（airborne laser scanning, ALS）数据集采集于加拿大西北地区特雷尔谷溪（Trail Valley Creek, TVC）的北极苔原站点，该区域下伏连续永久冻土。已对该ALS点云执行基础处理与滤波操作。基于将点云分类为地面点与植被点的结果，推导得到数字地形模型（Digital Terrain Model, DTM）以及植被平均高度与最大高度的栅格数据。本数据集附带详细元数据。
