    "description": "These data were created as part of the National Oceanic and Atmospheric Administration Office for Coastal Management's efforts to create an online mapping viewer called the NOAA Lake Level Viewer. It depicts potential lake level rise and fall and its associated impacts on the nation's coastal areas. The purpose of the mapping viewer is to provide coastal managers and scientists with a preliminary look at lake level change, coastal flooding impacts, and exposed lakeshore. The viewer is a screening-level tool that uses nationally consistent data sets and analyses. Data and maps provided can be used at several scales to help gauge trends and prioritize actions for different scenarios. The NOAA Lake Level Viewer may be accessed at: https:\/\/coast.noaa.gov\/llv.\n      \n      This metadata record describes the Lake Huron digital elevation model (DEM), which is a part of a series of DEMs produced for the National Oceanic and Atmospheric Administration Office for Coastal Management's Lake Level Viewer described above. This DEM includes the best available lidar and US Army Corps of Engineer dredge surveys known to exist at the time of DEM creation that met project specifications. This DEM includes data for Alcona, Alpena, Arenac, Bay, Cheboygan, Chippewa, Huron, Iosco, Mackinac, Presque Isle, Sanilac, St. Clair, and Tuscola counties in Michigan.\n      \n      The DEM was produced from the following lidar data sets:\n      1. 2013-2015 USACE NCMP Topobathy Lidar: Lake Huron (MI)\n      2. 2013 USACE NCMP Topobathy Lidar: Lake Michigan South (MI)\n      3. 2010 ARRA Lidar: 4 Southeast Counties (MI)\n      4. 2008 USACE NCMP Topobathy Lidar: Lake Huron (MI)\n      5. 2007 USACE NCMP Topobathy Lidar: Lake Huron (MI)\n      6. 2007 USACE NCMP Topobathy BE Lidar: Lake Michigan (MI), Lake Erie (PA), Lake Huron (MI)\n      7. 2006 USACE NCMP Topobathy Lidar: Lake Michigan (IN), Lake Erie (OH,PA), Lake Huron (MI)\n     \n\n      The DEM was produced from the following sonar data sets:\n      8. 2015 USACE Detroit District, Point Lookout Harbor, MI\n      9. 2015 USACE Detroit District, Au Sable Harbor, MI\n     10. 2015 USACE Detroit District, Hammand Bay Harbor, MI\n     11. 2014 USACE Detroit District, St. Mary's River, MI, West Neebish Channel\n     12. 2014 USACE Detroit District, St. Mary's River, MI, Middle Neebish Channel\n     \n     \n\n      The DEM is referenced vertically to the North American Vertical Datum of 1988 (NAVD88) with vertical units of meters and horizontally to the North American Datum of 1983 (NAD83). The resolution of the DEM is approximately 3 meters.",
