Summary

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 data were 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 October 5-11, 2021. Methodology similar to Wagner, D.M., Lund, J.W., and Sanks, K.M., 2020 [...]

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 post-nourishment data where dredge materials were placed to mitigate beach erosion. The data will be used to compare against pre-nourishment conditions of June, 2021. The LAS dataset is provided because it was used to generate the elevation surface of the surveyed area and can be used to generate additional DEMs with different resolutions.
