Summary

This dataset consists of three files containing northing, easting, and elevation ("XYZ") information for light detection and ranging (lidar) data representing the beach topography and near-shore bathymetry of Minnesota Point near the Duluth Entry of Lake Superior, Duluth, Minnesota. The point data is the same as that in the LAS dataset used to create a digital elevation model (DEM) for 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, [...]

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 prior to beach nourishment in areas of Minnesota Point near the Duluth Entry to Lake Superior that have been scoured by high water levels and heavy wave activity. This survey was completed to obtain baseline data and establish pre-nourishment conditions before placing dredge spoils to mitigate beach erosion in September 2021. The XYZ files are provided for input use in CAD and other computer programs that require space-delimited position and elevation information.
