Since 2010, NPS and partners have developed high resolution benthic habitat maps for six coastal parks in the Great Lakes, using a novel combination of LiDAR, multi-beam sonar, and satellite imagery. In addition to high resolution bathymetry, we collected photo and video imagery to validate substrate and benthic features documented in our mapping...
