LiDAR DEM Smoothing and the Preservation of Drainage Features

LiDAR DEM Smoothing and the Preservation of Drainage Features

Fine-resolution Light Detection and Ranging (LiDAR) data often exhibit excessive surface roughness that can hinder the characterization of topographic shape and the modeling of near-surface flow processes. Digital elevation model (DEM) smoothing methods, commonly low-pass filters, are sometimes appl...
