Abstract

The feature classes HYDROL and HYDROP contain vector lines and polygons representing the coastal shoreline and hydrography used in the creation of the Environmental Sensitivity Index (ESI) for Great Lakes - St. Clair / Detroit River System - 2019 ESI Geodatabase. The HYDROP (hydrography polygons) layer delineates the shoreline, and identifies areas as either Land or Water. The HYDROL (hydrography lines) layer includes features that are not captured in the HYDROP data layer, such as breakwaters, fenders, groins, jetties, and piers.

The study area includes a small portion of southern Lake Huron at its outlet, the St. Clair River (which flows out of Lake Huron), Lake St. Clair, the Detroit River (which flows into Lake Erie), a small portion of western Lake Erie, and adjacent lands and waters in southeastern Michigan.

As a whole, the ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil, and include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources.

None

Use Constraints:

DO NOT USE MAPS FOR NAVIGATIONAL PURPOSES. Management boundaries are not to be considered legal boundaries. Edges may have been altered for cartographic processes. Note that the ESI database should not be used to the exclusion of other pertinent data or information held by state or federal agencies or other organizations. Likewise, information contained in the database cannot be used in place of consultations with environmental, natural resource, and cultural resource agencies, or in place of field surveys. Recognize that the information contained in the ESI database represents known concentration areas or occurrences of natural, cultural, and human-use resources, but does not necessarily represent the full distribution or range of each species or resource. This is particularly important to recognize when considering potential impacts to protected resources, such as endangered species, wetlands, etc. Besides the above warnings, there are no use constraints on these data. Acknowledgement of the originators, publishers, contributors, and sources listed would be appreciated in products derived from these data.

Abstract:

The feature classes HYDROL and HYDROP contain vector lines and polygons representing the coastal shoreline and hydrography used in the creation of the Environmental Sensitivity Index (ESI) for Great Lakes - St. Clair / Detroit River System - 2019 ESI Geodatabase. The HYDROP (hydrography polygons) layer delineates the shoreline, and identifies areas as either Land or Water. The HYDROL (hydrography lines) layer includes features that are not captured in the HYDROP data layer, such as breakwaters, fenders, groins, jetties, and piers.

The study area includes a small portion of southern Lake Huron at its outlet, the St. Clair River (which flows out of Lake Huron), Lake St. Clair, the Detroit River (which flows into Lake Erie), a small portion of western Lake Erie, and adjacent lands and waters in southeastern Michigan.

As a whole, the ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil, and include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources.

Purpose:

The ESI data are intended to provide baseline environmental data for oil spill planning and response. The Clean Water Act with amendments by the Oil Pollution Act of 1990 requires response plans for immediate and effective protection of sensitive resources. The ESI data may be appropriate for many other coastal management efforts, though the original intent should be kept in mind.

Data Set Information

Data Set Scope Code: Data Set
Data Set Type: GIS Files
Maintenance Frequency: As Needed
Maintenance Note:

Data content is considered static once published. However, if issues with the Geodatabase linkages or table contents are identified, the Geodatabase and/or the associated Map Document may be updated. Assure most current data is being used by downloading from https://response.restoration.noaa.gov/esi_download and/or comparing modification dates provided at this site.

Data Presentation Form: Map (digital)
Entity Attribute Overview:

In addition to the geographic data layers and their attribute tables, an associated data table, SOURCES, is used to store the source data information in the ESI data structure. The geographic data layers containing resource information (in this case, HYDROL; HYDROP does not link to the SOURCE table) are linked to the SOURCES table using the SOURCE_ID. The entity-relationship diagram describes relationships between attribute tables in the ESI data structure.

The SOURCES data table is described in detail in this document as an Entity or "Child Item". See the Browse_Graphic section for a link to the entity-relationship diagram, which describes the way these tables relate to the geographic data layers and other attribute tables in the ESI data structure.

Activity Log

Activity Log 1

CC ID: 891201
Activity Date/Time: 2019-10
Activity Type: Metadata creation
Responsible Party: Katy Beckham (Research Planning)
Description:

Metadata for the Great Lakes - Straits of Mackinac and St. Clair / Detroit River System ESI atlases were initially created by Research Planning Inc. (RPI) in October 2019.

Activity Log 2

CC ID: 893381
Activity Date/Time: 2020-01
Activity Type: Metadata review, revision, and publication
Responsible Party: David Moe Nelson
Description:

Metadata for the Great Lakes - Straits of Mackinac and St. Clair / Detroit River System ESI atlases were reviewed, revised, and prepared for publication by NOAA in January 2020.

Technical Environment

Description:

The software packages used to develop the atlas are Environmental Systems Research Institute's ArcGIS for Desktop 10.4.1(R) and SQL SERVER(R) (version 2005). The hardware configuration is PCs with Windows Operating System 10.

Data Quality

Accuracy:

A multi-stage error checking process is used to verify both attribute accuracy and logical consistency throughout data production. The process includes a standardized data entry methodology, data review by in-house and external resource experts, a final Quality Assurance/Quality Control (QA/QC) process, and multiple automated logical consistency checks. Quantitative data (such as densities, counts, abundances, or concentrations) provided by resource experts for inclusion in the data set may vary widely in attribute accuracy, depending upon the methodology used to collect and compile such data. For a more detailed evaluation of source data attribute accuracy, contact the sources listed in the Lineage section.

Completeness Report:

These data represent linear hydrography and land/water polygons for the Great Lakes - St. Clair-Detroit River System.

Conceptual Consistency:

A multi-stage error checking process, described in the above Attribute Accuracy Report, is used to verify both attribute accuracy and logical consistency throughout data production. This process includes multiple automated logical consistency checks that test the files for missing or duplicate data, rules for proper coding, GIS topological consistencies, and SQL SERVER(R) to ArcGIS(R) consistencies. A final review is made by the GIS manager, before the complete Geodatabase and metadata are created. After the data are delivered to NOAA, they are again subjected to a several consistency checks, and processed into the final delivery format.

Lineage

Lineage Statement:

Sources and Process Steps cited below in this metadata record include those used for two distinct areas of the Great Lakes: the Straits of Mackinac in northern Michigan, and the St. Clair / Detroit River System in southeastern Michigan. This is because these two study areas were initially combined into a single ArcGIS geodatabase, before being separated for publication. As a final procedural step to prepare the geodatabases for publication, the spatial data data corresponding to each respective area were clipped in ArcGIS according to the two distinct geographic study areas.

Process Steps

Process Step 1

CC ID: 891220
Description:

The HYDROL dataset was derived from the National Shoreline composite (2011) and verified using ESRI Basemap World Imagery (2010-2017) as well as Google Earth imagery (2014-2018). Piers and docks were trimmed/extended to match the shoreline if this was implied; however, structures such as groins, jetties, fenders, and breakwaters that appeared to extend inland of the shoreline were left as is.

Process Date/Time: 2019-09-23 00:00:00
Process Contact: Office of Response and Restoration (ORR)

Process Step 2

CC ID: 891221
Description:

The land and water polygons in the area of interest (RPI 2018-2019) for the HYDROP dataset were derived primarily from digital coastline data originating from the integration of the National Oceanic and Atmospheric Administration (NOAA) Continually Updated Shoreline Product (CUSP, 2006-2007) and National Shoreline composite (2011); the U.S. Geological Survey (USGS) high resolution National Hydrography Dataset (NHD, 2011-2016); the U.S. Fish and Wildlife Service (USFWS) National Wetlands Inventory (NWI) dataset (1975-2013); the Ontario Ministry of Natural Resources dataset (1998-2018) and manual digitization at 1:4,000 from BING Bird’s Eye and Aerial imagery (2012-2019), ESRI Basemap World Imagery (2010-2017), and Google Earth aerial imagery (2014-2018). The most recent shoreline was utilized where available. Additional sources used to verify ESI classification and identify land and water polygons included: U.S. Army Corps of Engineers Oblique Imagery (2012), Marinas.com (2018, Marinas only), and Land Use 2010 from Agriculture and Agri-Food Canada.

Email Address: orr.esi@noaa.gov

Process Step 3

CC ID: 891222
Description:

Depending on the type of source data, four general approaches are used for compiling these data layers: 1) hardcopy maps are digitized at their source scale; 2) digital data layers are evaluated and used "as is" or integrated with the other data sources; 3) overflight classifications are digitized from the scanned and registered hardcopy field maps; and/or 4) classifications are interpreted from oblique gps referenced photography or video taken during the overflights. After the initial shoreline classification, these data are edgematched and checked for logical consistency errors. Review maps are plotted at 1:50,000 scale for verification of polygonal and linear attributes. See the Lineage section for additional information on the type of source data for this data layer. The ESI, biology, and human-use data are compiled into the standard ESI digital data format. A second set of interviews with participating resource experts are conducted to review the compiled data. If necessary, edits to the HYDROL and HYDROP data layers are made based on the recommendations of the resource experts, and final hardcopy maps and digital data are created.

Email Address: orr.esi@noaa.gov

Process Step 4

CC ID: 896256
Description:

Sources and Process Steps cited above in this metadata record include those used for two distinct areas of the Great Lakes: the Straits of Mackinac in northern Michigan, and the St. Clair / Detroit River System in southeastern Michigan. This is because these two study areas were initially combined into a single ArcGIS geodatabase, before being separated for publication. As a final procedural step to prepare the geodatabases for publication, the spatial data data corresponding to each respective area were clipped in ArcGIS according to the two distinct geographic study areas.
