2021 NOAA Bathymetric Lidar: Sleeping Bear Dunes National Lakeshore, MI
Woolpert, Inc. was contracted to acquire and process high-resolution topo-bathy lidar to support mapping and modeling needs at the Sleeping Bear Dunes National Lakeshore (SLBE), which will be used for the creation of new benthic mapping products using the Coastal and Marine Ecological Classification Standard (CMECS). Woolpert sub-contracted NV5 to acquire the lidar data using their HawkEye 4X topo-bathy lidar sensor, to provide high density topo lidar with an ANPS of greater than or equal to 1 pulse per square meter with a vertical accuracy of less than or equal to a 15 cm RMSE for the bathymetric lidar.
Woolpert also collected topographic ground control and check points covering some extended survey lines.
This dataset is the classified lidar point cloud in LAS v. 1.4 format. collected on August 31 and September 3, 2021 using a Leica HawkEye4X sensor. Classifications are as follows: 1 - Unclassified, 2 - Ground, W7 - Low Point (Noise), 9 - Water Surface Topo, W18 - High Noise, 40 - Bathymetric Point, 41 - Water Surface Bathy, S42 - Derived Water Surface, 43 - Submerged Object, W45 - No Bottom Found At
In addition to these lidar point data, the bare earth Digital Elevation Models (DEM) created from the lidar point data are also available. These data are available for custom download at the link provided in the URL section of this metadata record.
