Data Management Plan

These feature classes reside within the SOCECON Feature Data Set of the Great Lakes St. Marys River - 2021 ESI Geodatabase. They contain vector lines and points representing Socioeconomic human-use resource data for the Great Lakes St. Marys River System and adjacent lands and waters. The study area includes the St. Marys River at the southern portion of Lake Superior beginning just east of Monocle Lake and south of Iroquois Island ending to the headwaters of Lake Huron.

These data sets contain information about the following resources: airports, archaeological sites, abandoned vessels, beaches, historical sites, pipelines, and rail routes in the St. Marys River.

Object specific Type and Source information are stored in the related data tables, SOC_DAT and SOURCES (described below). These are stand-alone tables within the Geodatabase, designed to be used in conjunction with these spatial data layers.

This data set is a portion of the ESI data for Great Lakes St. Marys River System. 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.

Process Steps:

• 2021-07-01 00:00:00 - Information on socioeconomic features within the Great Lakes St. Marys River - 2021 ESI study region were acquired from multiple sources. Socioeconomic features include airports, archaeological sites, abandoned vessels, beaches, historical sites, pipelines, and rail routes in the St. Marys River. The main sources of data that were used to depict human-use resources for this data layer include: 1) personal interviews and digital data provided by resource experts from the Michigan Department of Natural Resources (MIDNR); 2) digital data provided by the U.S. Department of Transportation (USDOT) Federal Aviation Administration (FAA) Aeronautical Information Services, NOAA's Office of Coast Survey (NOAA OCS) Automated Wrecks and Obstructions Information System (AWOIS), Google maps, U.S. Energy Information Association (USEIA), and the Michigan Geographic Framework (MGF). Locations of airports were downloaded from the United States Department of Transportation (USDOT) Federal Aviation Administration (FAA) – Aeronautical Information Services. Generic archaeological sites were provided by Michigan Department of Natural Resources (MIDNR). Data on locations of abandoned and derelict vessels comes from NOAA’s Office of Coast Survey Automated Wrecks and Obstructions Information System (AWOIS). Locations of recreational beaches used for activities such as swimming, sun-bathing, fishing, etc., were located via Google maps. Historical sites from Michigan Department of Natural Resources (MIDNR) depict point locations of Michigan’s historical markers. Major crude oil pipelines were provided by the U.S. Energy Information Association (USEIA). Locations of railways were downloaded from the Michigan Geographic Framework (MGF).
• 2021-07-01 00:00:00 - These data were developed as SOCECON_POINTS and SOCECON_LINES within the Great Lakes St. Marys River - 2021 ESI study region, following ESI Guidelines. Additional data are contained in the joined table SOC_DAT using HUNUM as a unique ID, and in SOURCES using SOURCE_ID as a unique ID. Depending on the type of source data, three general approaches are used for compiling the data layer: 1) information gathered during initial interviews and from hardcopy sources are compiled onto U.S. Geological Survey 1:50,000 topographic quadrangles and digitized; 2) hardcopy maps are digitized at their source scale; 3) digital data layers are evaluated and used "as is" or integrated with the hardcopy data sources. A second set of interviews with participating resource experts are conducted to review the compiled data. If necessary, edits to the SOCECON_POINT or SOCECON_LINE data layers are made based on the recommendations of the resource experts, and final hardcopy maps and digital data are created.
