Product: Classified LAS 1.4 files formatted to 1,652 individual 1,000 m x 1,000 m tiles for the Rogue River Siskiyou Project Area. Geographic Extent: This dataset and derived products encompass an area covering approximately 569 square miles within Siskiyou and Del Norte Counties in California as well as Josephine and Jackson Counties in Oregon. Dataset Description: The Rogue River Siskiyou lidar project called for the planning, acquisition, and processing of lidar data collected at an aggregate nominal pulse spacing (ANPS) of 0.35 meters. Project specifications are based on the U.S. Geological Survey National Geospatial Program Base lidar Specification, Version 1.3. The data was developed based on the NAD83(2011) horizontal datum and NAVD88 (GEOID12B) vertical datum. Data was projected in UTM Zone 10N. Lidar data was delivered as processed Classified LAS 1.4 files, formatted to 1,652 individual 1,000 m x 1,000 m tiles. Derived products include: tiled Intensity Imagery, tiled DZ orthos, tiled hydroflattend bare earth DEMs and 3D waters edge breaklines. Ground Conditions: Lidar was collected in fall 2019, while the presence of snow on the ground was at a minimum and rivers were at or below normal levels. In order to post process the lidar data to meet task order specifications and meet ASPRS vertical accuracy guidelines, QSI established a total of 65 ground control points distributed throughout the Rogue River Siskiyou, Oregon project area. Lidar data was calibrated to these known ground locations. An additional 70 independent accuracy checkpoints, 43 in Bare Earth and Urban landcovers (NVA points) and 27 in Shrub, Tall Grass, and Forest categories (VVA points) were used to assess the vertical accuracy of the project data. These checkpoints were not used to calibrate or post process the data. The NOAA Office for Coastal Management (OCM) downloaded the: 1. Lidar point data from this USGS site: ftp://rockyftp.cr.usgs.gov/vdelivery/Datasets/Staged/Elevation/LPC/Projects/OR_RogueSiskiyouNF_2019_B19/OR_RogueRiverSiskiyouNF_B1_2019/ 2.
