MBES bathymetry of Lake Michigan nearshore near Ogden Dunes/Burns Harbor, Indiana, July 25, 2016

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2020-08-14T00:00:00Z
These data are high-resolution bathymetry (lake bottom elevation) in XYZ format, generated from the July 25, 2016, topographic and hydrographic survey of Lake Michigan in an area near Ogden Dunes, Indiana. Hydrographic data were collected using a multibeam echo-sounder (MBES) with integrated inertial navigation solution (INS) mounted on a marine survey vessel. Data were collected as the vessel traversed the lake along survey lines distributed throughout the area. Data collection software integrated and stored the depth data from the multibeam sonar and the horizontal and vertical position and attitude data of the vessel from the INS in real time. Data processing required computer software to extract bathymetric data from the raw data files and to summarize and map the information.
