Abstract
This data represents LiDAR elevation information for the St. Louis River Area of Concern in Douglas County, Wisconsin in 2015. The following derivative products are available: classified LAS, contours, hydro breaklines, hydro-enforced (breakline) DEM, countywide DEM, tiled DEM, countywide DSM, intensity images, and tiled DSM. [The St. Louis River Area of Concern project area covers approximately 308 square miles. Lidar data was acquired with a nominal point spacing (NPS) of 0.7 meters . Project specifications are based on the U.S. Geological Survey National Geospatial Program Base LIDAR Specification, Version 1.0. The data was developed based on a horizontal projection/datum of Coordinate System: NAD_1983_UTM_Zone_15N, Meters and vertical datum of NAVD1988 (GEOID12A), Meters. LiDAR data was acquired using the Orion Optech H300 sensor. Collection occurred from October 17-19, 2015, while no snow was on the ground and rivers were at or below normal levels.]
Purpose
This data is intended for reference and mapping purposes, and may be used for basic applications such as viewing, querying, and map output production, or to provide a basemap to support graphical overlays and analysis with other spatial data. [This data, along with its derivitives, is part of a watershed stressor and habitat assessment in the larger Nemadji River watershed. This data was produced all from lidar information as of 2015.]
Supplemental Information
Data is available for download from: https://web.s3.wisc.edu/wsco-wisconsinview/lidar/Douglas/St_Louis_River_Area_of_Concern_2015/SLRAOC_2015_WDNR_Delivery_COMPLETE/ Detailed, original metadata accompanying this LiDAR data is available inside the ‘Metadata’ folder from WisconsinView. Classified LAS: Point classification using semi-automated techniques on the point cloud to assign the feature type associated with each point. Lidar points can be classified into a number of categories including bare earth or ground, top of canopy, and water. The different classes are defined using numeric integer codes in the LAS files. Contours: A line through all contiguous points of equal elevation value. Contours are vector features used to represent the elevation of a landscape in a relatively familiar way. They are typically used for basemaps and general topographic representation. Hydro Breaklines: Breaklines maintain the definition of water-related features in an elevation model. They are used to capture linear discontinuities in the surface, lake shorelines, single-line drains for small rivers, and double-line drains for large rivers. Countywide Digital Elevation Model (DEM): A DEM represents the bare-Earth surface, removing all natural and built features. The dataset contains a single file covering the entire county. Tiled Digital Elevation Model (DEM): A Digital Elevation Model (DEM) represents the bare-Earth surface, removing all natural and built features. The data contains (possibly) hundreds of individual files available to download as small tiled geographic areas over the extent of an entire county. Digital Surface Model (DSM): A Digital Surface Model (DSM) captures both the natural and built/artificial features of the environment.

[None. However, temporal changes to the Earth's surface may have occurred since the acquisition of the lidar data and may no longer represent current bare earth surface conditions.]
