Abstract
Stream networks shown on public maps are often incomplete and their accuracy fails to meet the full needs of forest managers. Stream Network Extraction (SNE) from a LiDAR Digital Elevation Model (DEM) has the potential to add to the already mapped streams and provide more hydrographical information. This report describes the potential of two different SNE programs with a LiDAR-derived DEM.
