    • 2016 South Manitou Island, MI Benthic Cover-Geodatabase

    Metadata Updated: March 15, 2024

    This dataset has been developed for the National Oceanic and Atmospheric Administration's (NOAA) Office for Coastal Management (OCM) as a collaborative and cooperative project with the National Park Service (Sleeping Bear Dunes National Lakeshore). A workflow combining photointerpretation, object-based image analysis, field verification, and expert manual interpretation has produced benthic habitat maps including CMECS Substrate and Biotic Components for a 42km2 project area at South Manitou Island in Lake Michigan. The Substrate and Biotic Components were classified to at least the CMECS Subclass level. For both components, Co-Occurring Elements and Modifiers (i.e. Percent Cover, Induration, Surface Pattern) were added to provide further detail to CMECS units. Refer to project report for example images and corresponding CMECS classifications. This file geodatabase contains the Substrate and Biotic components as separate feature layers. Several existing data sets formed the source for the mapping effort, including underwater photography, aerial imagery, and acoustic backscatter (side-scan and multi-beam sonar). High-resolution LIDAR data was also collected around the island in 2016 which also was used to support the mapping. Field observations were collected over 2 days in August 2017 to assure the accuracy of the map products. In addition to the Substrate and Botic data, this file Geodatabase also contains field validation points collected during summer of 2017, a GPS navigation track for each field site, and digital video clips for many of the sites.
