This study area encompasses the Saginaw Bay region of the state of Michigan. Please refer to the process steps and https://glcwra.wim.usgs.gov/ for further explanation on the methods. The purpose of the study area is to define the extent of GLCWRA's restoration assessment for the SBRA. This vector layer was used as a geographic limit for all other datasets associated with the SBRA (parameters 0-6 and the DEM). The purpose for releasing version 2.0 of these datasets is that they were created with more recent and more accurate input data. For changes between versions 1.0 and 2.0, please see the Release History text file. 2024 publication date Complete None planned -84.2818 -82.4771 44.5432 43.1146 ISO 19115 Topic Category environment geoscientificInformation inlandWaters Marine Realms Information Bank (MRIB) keywords lake lakeshore wetland wetland restoration stream river hydrology resource management USGS Thesaurus hydrology natural resource management water quality remediation wetland ecosystems Holocene Common geographic areas Great Lakes Lake Huron Saginaw Michigan None.

Digital datasets obtained from public repositories and datasets including the National Hydrography Dataset (NHD), National Wetland Index (NWI), 3D Elevation Program (3DEP), U.S. Census Bureau, National Geospatial Program, U.S. Fish and Wildlife Service, National Oceanic and Atmospheric Association (NOAA), Protected Areas Database of the U.S. (PAD-US), National Land Cover Database (NLDC), Gridded Soil Survey Geographic Database (gSSURGO), Coastal Change Analysis Program (C-CAP) U.S. Geological Survey 2016 application/service Geonarrative map website for GLCWRA study https://glcwra.wim.usgs.gov/ The attribute values of this dataset were inspected and confirmed to be within the proper range of values. The attribute values were reviewed, and spatial data was visually inspected to verify the that the data values and their locations accurately describe the purpose of the data. This dataset is considered complete for the information presented, as described in the abstract. This dataset provides coverage for the entire Saginaw Bay Restoration Assessment study area. Approximately 20% of the spatial data was visually inspected to verify the positional accuracy of its features. The review consisted of comparing the spatial data to its input datasets and to underlying GIS basemaps. While this data has been reviewed, the spatial data is only as spatially accurate as the input data sources. This dataset does not have a vertical component, so testing for vertical accuracy was not necessary.

This elevation is 1 meter above the maximum water level from the NOAA water level gage 9075035 which is the most centrally located gage in the study area. The contour line was then buffered by 1 kilometer using the 'Buffer' tool (Side Type = Full, End Type = Round, Method = Planar, Dissolve Type = Dissolve all output features into a single feature). 20230915 A second buffer polygon was created by buffering the portion of the shoreline of Lake Huron within the area of interest by 2 kilometers by using the 'Buffer' tool (Side Type = Full, End Type = Round, Method = Planar, Dissolve Type = Dissolve all output features into a single feature). Then this buffer polygon and the polygon created in the previous step were merged together using the 'Merge' tool. The resulting polygon represents the SBRA study area. 20230915 Vector G-polygon 1 Universal Transverse Mercator 17 0.9996 -81.0 0.0 500000.0 0.0 coordinate pair 0.6096 0.6096 meters North_American_Datum_1983 GRS_1980 6378137.0 298.257222101 SBRA_Study_Area.shp Vector dataset (in shapefile format) containing the boundary of the SBRA study area.
