* » Abstract

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.

This metadata record describes the Lake Michigan 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, US Army Corps of Engineer dredge surveys, and National Park Service multibeam data known to exist at the time of DEM creation that met project specifications. This DEM includes data for Allegan, Antrim, Benzie, Berrien, Charlevoix, Delta, Emmet, Grand Traverse, Leelanau, Mackinac, Manistee, Mason, Menominee, Muskegon, Oceana, Ottawa, Schoolcraft, and Van Buren counties in Michigan; Lake, La Porte, and Porter Counties in Indiana, Cook and Lake Counties in Illinois, and Brown, Door, Kenosha, Kewaunee, Manitowoc, Marinette, Milwaukee, Oconto, Ozaukee, Racine, and Sheboygan Counties in Wisconsin.

The DEM was produced from the following lidar data sets:

1. 2016 NOAA Topobathy Lidar: Upper Lake Michigan Islands

2. 2015 FEMA Marinette County

3. 2013 Indiana Statewide Lidar Collection: Lake, La Porte, Tippecanoe, Newton, Jasper and Porter County Buy-Up

The DEM was produced from the following NPS multibeam sonar data sets:

40. 2011, National Park Service, Sleeping Bear Dunes National Lakeshore Multibeam Sonar

41. 2012, National Park Service, Sleeping Bear Dunes National Lakeshore Multibeam Sonar

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.
* Purpose

The NOAA Office for Coastal Management has developed high-resolution digital elevation models (DEMs) for use in the Office's Lake Level Viewer internet mapping application. These DEMs serve as source datasets used to derive data to visualize the impacts of inundation and shore exposure resulting from lake level change along the coastal United States in the Great Lakes.

The DEM is derived from the source lidar and sonar data. Horizontal accuracy testing is not performed on the DEM. Lidar source data assumed to meet 1 meter horizontal accuracy.
Vertical Positional Accuracy

The DEM is derived from the source lidar and sonar data. Vertical accuracy is not tested on the DEM. Project specifications require all source lidar data used in constructing the DEM to meet FEMA Specifications for Flood Hazard Mapping.

Completeness Report

A visual qualitative check was performed to ensure data completeness. All available lidar and sonar data known at the time of DEM creation that meets project specifications has been used to develop the DEM. Known data gaps may exist where lidar and sonar coverage was incomplete.
Conceptual Consistency

Data covers the tile scheme provided for the project area. Elevation data checked for anomalous elevation values outside expected range.

Process Step Number 2
» Description

Source elevation data and their associated hydro-breaklines, where available, were downloaded. Data were then reviewed and edited to meet the project's requirements. The major requirements were delineating data extent for topography and bathymetry; removing areas less than 0.01 square kilometers; creating separate terrain datasets for topography and bathymetry; converting to rasters; and mosaicing the topography and bathymetry together for the final product. NOAA's VDatum datum conversion tool was used to convert geoids.
