2015 NOAA Lidar: Pelekane Watershed (HI)

This metadata describes the Digital Elevation Model (DEM) 1 meter products derived from the airborne LiDAR data collected in August of 2015 for the Pelekane Watershed on the big island of Hawaii. The point cloud dataset was acquired with an Optech Orion M300 Airborne LiDAR Terrain Mapper with a nominal point spacing of 0.33 m. The DEM for this delivery was made from airborne LiDAR in LP360. A triangulated irregular network (TIN) was generated based on the LiDAR ground information (Using the tenderloin part of the point cloud only), and was later converted in a 1-meter raster file (DEM). Horizontal positions are referenced to UTM Zone 5 North (NAD83 PA11). Vertical elevations are in an orthometric datum derived from applying Geoid12b to NAD83(2011) ellipsoid heights and are in meters.
