LiDAR-derived Products for the Dry Creek Watershed, Idaho
Idaho LiDAR Consortium
Light Detection and Ranging (LiDAR) has emerged as a promising technology in many disciplines, including geology, forestry, and hydrology. Despite a growing body of LiDAR literature, gaps in information on issues related to acquisition and processing of LiDAR data still exist (Gatziolis and Andersen, 2008). In recent years, various efforts have been made, at state level and beyond, for web-based distribution of raw LiDAR data (e.g. OpenTopography, CLICK) as well as LiDAR-derived products (e.g. INSIDE Idaho). However, proper processing of raw data, and documenting the processing steps in a standard-compliant metadata are essential before LiDAR data and value-added products can be made available to the public domain through data portals. This data provides a demonstration of a LiDAR workflow for NSF Idaho EPSCoR project Water Resources in a Changing Climate.
This is collection level metadata for LAS files collected by University of Idaho, College of Natural Resource, Moscow, ID as a part of a larger project to use LiDAR for studying eco-hydrology and snow modelling. The lidar survey was conducted by vendor Watershed Sciences, Corvallis, OR. Leica ALS50 Phase II lidar instrument was flown in a Cessna Caravan 208B aircraft over the period of November 10-18, 2007. The data was delivered in LAS 1.1 format with information on return number, easting, northing, elevation, scan angle, and intensity for each return.
