Airborne Laser Scanning (ALS) Point Clouds of Trail Valley Creek, NWT, Canada (2018)

The airborne laser scanning (ALS) datasets were acquired at the Arctic tundra site of Trail Valley Creek (TVC), Northwest Territories, Canada (68°44'25'' N 133°29'36'' W, Marsh et al. 2008), which is underlain by continuous permafrost. The point cloud data were acquired...

Description
Summary:The airborne laser scanning (ALS) datasets were acquired at the Arctic tundra site of Trail Valley Creek (TVC), Northwest Territories, Canada (68°44'25'' N 133°29'36'' W, Marsh et al. 2008), which is underlain by continuous permafrost. The point cloud data were acquired with a Riegl LMS-Q680i airborne laser scanner on board the Alfred Wegener Institute's POLAR-5 science aircraft. 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. OPALS software was used to process the raster (tif). Detailed metadata are included.
