Product: These lidar data are processed Classified LAS 1.4 files, formatted to 1773 individual 1000 m x 1000 m tiles.
Geographic Extent: 7 counties in Oregon, covering approximately 684 total square miles.
Dataset Description: The Wallowa-Whitman National Forest project called for the planning, acquisition, processing, and derivative products of lidar data to be collected at a nominal pulse spacing (NPS) of 0.35 meters. Project specifications are based on the U.S. Geological Survey National Geospatial Program Base LiDAR Specification, Version 1.3. LiDAR data were delivered as processed Classified LAS 1.4 files formatted to 1773 individual 1000 m x 1000 m tiles. Continuous breaklines were produced in Esri file geodatabase format.
Ground Conditions: Lidar was collected in summer 2020, while no snow was on the ground and rivers were at or below normal levels. Twenty-seven independent accuracy checkpoints, 27 in Bare Earth and Urban landcovers (27 NVA points) were used to assess the vertical accuracy of the data. These checkpoints were not used to calibrate or post process the data.
The original lidar specification information has been retained below. However, the class system does not match the data as received by NOAA from USFS, nor the current class system. See the processing lineage for more detail.
This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
