The project vendor, Woolpert, Inc., acquired highly accurate Light Detection and Ranging (lidar) elevation data for the Duluth area during the Fall of 2012. Lidar data are in the UTM Zone 15 coordinate system, NAD83 96, NAVD88 Geoid09 meters tiled by USGS 1/16, 1:24,000 quadrangles.

The vendor delivered the data to the Minnesota Department of Natural Resources (DNR) in several formats:

1) One-meter digital elevation model
2) Edge-of-water breaklines
3) Classified LAS formatted point cloud data

DNR staff created four additional products: two-foot contours, building outlines, hillshades and a difference grid between this data and lidar data collected in 2011.

This metadata record was created at the Minnesota Geospatial Information Office by combining information supplied by Woolpert and DNR.

This dataset is a LAS (industry-standard binary format for storing lidar point clouds) dataset containing light detection and ranging (lidar) data and sonar data representing the beach and near-shore topography of Lake Superior at Minnesota Point, near the Duluth entry, Duluth, Minnesota. Average point spacing of the LAS files in the dataset are as follows: lidar, 0.094 meters (m); multibeam sonar, 0.501 m; single-beam sonar, 1.876 m. The LAS dataset was used to create digital elevation models (DEMs) of 10 m (32.8084 feet) and 1 m (3.28084 feet) resolution, of the approximate 1.75 square kilometer surveyed area. Lidar data were collected August 22, 2022 using a boat mounted Velodyne VLP-16 unit and methodology similar to that described by Huizinga and Wagner (2019). Multibeam sonar data were collected August 22-23, 2022 using a Norbit integrated wide band multibeam system compact (iWBMSc) sonar unit and methodology similar to that described by Richards and Huizinga (2018). Single-beam sonar data were collected August 23, 2022 using a Ceescope echosounder and methodology similar to that described by Wilson and Richards (2006).This project followed similar methods to that of Wagner, Lund, and Sanks (2020), who completed a similar survey in 2019.

This dataset contains lidar-derived elevation products for the Minnesota portion of the Red River of the North Basin. The Minnesota Department of Natural Resources (DNR) processed the data to make it consistent with other lidar data available in Minnesota, including converting it to UTM Zone 15 coordinates and tiling to 3.25 square mile blocks based on 1/16 of a standard USGS 1:24,000 quadrangle.

Data covers the following Minnesota counties: Becker, Beltrami, Big Stone, Clay, Clearwater, Grant, Kittson, Koochiching (northern portion), Lake of the Woods, Mahnomen, Marshall, Norman, Otter Tail, Pennington, Polk, Red Lake, Roseau, Stevens, Traverse, Wilkin. Products included are: One- and three-meter DEMs, one- and three-meter hillshades, and two-foot contours, plus a tile index map for each county. Since breaklines were not available for all of the Minnesota portion of the basin, the data has not been hydro-flattened.

The original data was provided by the International Water Institute (IWI) and the United States Geological Survey. IWI's Red River Basin Mapping Initiative acquired a highly accurate digital elevation model (DEM) for the Red River of the North Basin south of the U.S./Canada border in UTM Zone 14 coordinates.

This metadata record was created at the Minnesota Geospatial Information Office by combining information from the IWI and DNR.

This dataset is a LAS dataset containing light detection and ranging (lidar) data and multibeam sonar data representing the beach topography and near-shore bathymetry of Minnesota Point near the Duluth Entry of Lake Superior, Duluth, Minnesota. The LAS dataset used to create a digital elevation model (DEM) of the approximate 1.87 square kilometer surveyed area. Lidar data were collected using a boat mounted Velodyne VLP-16 unit. Multibeam sonar data were collected using a Norbit integrated wide band multibeam system compact (iWBMSc) sonar unit. Single-beam sonar data were collected using a Ceescope sonar unit. All elevation data were collected June 22-24, 2021. Methodology similar to Wagner, D.M., Lund, J.W., and Sanks, K.M., 2020 was used.

The original data was classified bare-earth lidar DEM and photogrammetrically derived breaklines generated from lidar intensity stereo-pairs in Esri ASCII 3D Generate format and Microstation SE .dgn format for Blue Earth County, Minnesota. The data was further processed by the Minnesota Department of Natural Resources to create and distribute feature classes in this geodatabase version.

The lidar data for Blue Earth County was collected under contract by the county. Thus, the data format is not entirely consistent with some of the other lidar data available in Minnesota. Specifically, the Blue Earth county collect only required classification of Bare Earth in the lidar LAS files, so there is no information on buildings, vegetation, or model key points.

Breaklines captured as part of this effort are also a bit different since they are 3D Polyline features rather than 3D Polygon features. They also include road centerlines, stream courses and other features that are not part of the Statewide collect specifications.

The LiDAR data for Stearns County was collected under contract by the county. Thus, the data format is not entirely consistent with some of the other LiDAR data collected by the State of Minnesota. Specifically, the Stearns County collect required classification of only Bare Earth returns in the LiDAR LAS files, so there is no information on buildings, vegetation, or model key points.

Breaklines captured as part of this effort are also a bit different. In Stearns County, the breaklines are 3D Polyline features rather than 3D Polygon features. They also include road centerlines, stream courses and other features that are not part of the Statewide collect specifications.

The following data was delivered to the Minnesota Department of Natural Resources (DNR):

1. Bare Earth LAS files
2. 1-foot DEMs
3. Breaklines (edge of water, curb and centerlines)

DNR staff created the two-foot contours.

The lidar data for McLeod County was collected under contract by the county. Thus, the data format is not entirely consistent with some of the other lidar data collected by the State of Minnesota. Specifically, the McLeod County collect required classification of only Bare Earth in the lidar LAS files, so there is no information on buildings, vegetation, or model key points. The LAS data used for this process were acquired from the U.S. Geological Survey. No breaklines were available for processing this data.

This metadata record was created at the Minnesota Geospatial Information Office using information supplied by McLeod County and the Minnesota Department of Natural Resources.
