Abstract:
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.
