2017 USGS Lidar: Forest County, WI

NOAA
The Forest County lidar project area covers approximately 1056 square miles which includes a 100 meter buffer around the county boundary. The lidar data was acquired at a nominal point spacing (NPS) of 0.7 meters and a single swath nominal point density (NPD) of 2.0. Project specifications are based on Forest County requirements and on the U.S. Geological Survey National Geospatial Program LiDAR Base Specification, Version 1.2. The data was developed based on a horizontal projection/datum of NAD83(2011) / Forest County (ftUS) (EPSG Code: 7606), and vertical datum of NAVD88 - Geoid12B (Feet). LiDAR data was acquired using the Leica ALS70 SN7161 and SN7178 sensors from April 22, 2017 through April 25, 2017 in seven total lifts. Acquisition occurred with leaves absent from deciduous trees, when no snow was present on the ground, and with rivers at or below normal levels. Data were converted to ellipsoid heights in meters and geographic coordinates for ingest into the Digital Coast Data Access Viewer. Further conversion may be done there using this metadata as a template. There may also be an orthometric download available (see Distribution section). This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
