- Abstract
- This data represents LiDAR elevation information for Pepin County, WI in 2019. The following derivative products are available: classified LAS, hydro breaklines, and tiled DEM. Also included are several countywide products created by the WisconsinView Partners - the WI Department of Administration’s Geographic Information Office in collaboration with the UW-Madison Space Science and Engineering Center’s (SSEC) WisconsinView repository. Original lidar data in tiled format from federal (USGS 3DEP) and/or local county lidar projects were used to create countywide mosaics of specific datasets such as DEMS, Intensity values and DSMs in various projections and coordinate systems. [The Pepin County lidar project area covers approximately 255 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 aggregate nominal point density (ANPD) of 2.0. Project specifications are based on Pepin County requirements and on the U.S. Geological Survey National Geospatial Program LiDAR Base Specification, Version 1.3. The data was developed based on a horizontal projection/datum of NAD83(2011) / Pepin County (ftUS) (EPSG Code: 7624), and vertical datum of NAVD88 - Geoid12B (Feet). LiDAR data was acquired using the Riegl VQ 1560i SN061 Sensor on May 4, 2019 in 1 total lift. Acquisition occurred with leaves absent from deciduous trees, when no snow was present on the ground, and with rivers 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 derivatives, is the result of a countywide elevation mapping with cooperative partnerships from Pepin County, Wisconsin DOA, and the USGS 3DEP program. This data was produced from lidar data collected in May 2019, which was processed and delivered in 2020.]
- Supplemental Information
- Data is available for download from: https://web.s3.wisc.edu/wsco-wisconsinview/lidar/Pepin/Pepin_2019_3DEP_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. 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. 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.
