- Abstract
- This data represents LiDAR elevation information for the City of Superior in Douglas County, Wisconsin in 2019. The following derivative products are available: classified LAS, contours, hydro breaklines, citywide DEM, and derived terrain.[EagleView acquired highly accurate Light Detection and Ranging (LiDAR) elevation data for WICSUP19. The area of interest is comprised of approximately 45.5 square miles. The horizontal data projection is NAD 1983 HARN WISCRS Douglas County US Survey Feet and the vertical datum is NAVD88 Geoid12B. LiDAR for this dataset was classified and quality controlled by EagleView.]
- 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. [The purpose of this dataset is to provide a high accuracy land surface model for WICSUP19 and provide geographic products to the client. These products include a LiDAR point cloud with standard classification, a bare-Earth digital elevation model (DEM) in ArcGIS GRID format with a cell-size of 3ft, and elevation contours with an interval of 1ft.]
- Supplemental Information
- Data is available for download from: https://bin.ssec.wisc.edu/pub/wisconsinview/lidar/Douglas/CityofSuperior_2019_City_Delivery/ 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. Derived Terrain: A vector data set composed of regularly spaced points and natural features such as ridges and breaklines. A DTM augments a DEM by including linear features of the bare-earth terrain 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. Citywide 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 city.
