Hanson, J.L., Sattler, S.R., and Lund, J.W., 2021, XYZ dataset of lidar and multibeam data collected at Lake Superior at the Duluth Entry, Duluth, MN, September 2020: U.S. Geological Survey data release, https://doi.org/10.5066/P9JH0O1X.

Summary

This dataset consists of two files containing northing, easting, and elevation ("XYZ") information for light detection and ranging (lidar) data representing the beach and near-shore topography of Lake Superior at the Duluth Entry, Duluth, Minnesota. The point data is the same as that in the LAS dataset used to create a digital elevation model (DEM) of the approximately 1.87 square kilometer surveyed area. Lidar data were collected September 23, 2020 using a boat mounted Velodyne unit. Multibeam sonar data were collected September 22-23, 2020 using a Norbit integrated wide band multibeam system compact (iWBMSc) sonar unit. Methodology similar to Wagner, D.M., Lund, J.W., and Sanks, K.M., 2020 was used.

Purpose

Data were collected in cooperation with the U.S. Army Corps of Engineers (USACE), Detroit District, to define beach topography and near-shore bathymetry areas that have been scoured by high water levels and wave activity. This post-placement survey was completed to evaluate movement of placed material and overall changes to the barrier island and surrounding nearshore area. The XYZ files are provided for input use in CAD and other computer programs that require space-delimited position and elevation information.
