These meadows provide shelter for juvenile fish, and invertebrates. In certain locations they also help stabilize unconsolidated sediments and shorelines. Maine's Department of Marine Resources has mapped the SAV habitat for the entire coast using the Coastal Change Analysis Protocol. This mapping was accomplished from aerial photography acquired between 1993 and 1997. The unified coastal SAV data set is a composite of these multiple year data. The benthic data is classified according to the System for Classification of Habitats in Estuarine and Marine Environments (SCHEME). This system is fully described in "Development of a System for Classification of Habitats in Estuarine and Marine Environments (SCHEME) for Florida, Report to U.S. EPA - Gulf of Mexico Program, Florida Fish and Wildlife Conservation Commission, Florida Marine Research Institute. Review Draft 12/04/02." Original contact information: Contact Org: NOAA Office for Coastal Management Phone: 843-740-1202 Email: coastal.info@noaa.gov The state of Maine is mapping and monitoring SAV beds to assist in locating sensitive areas for protection in the event of an oil spill. The SAV maps also will form a baseline to determine trends in this system. completed NOAA Office for Coastal Management (843) 740-1202 2234 South Hobson Ave Charleston SC 29405-2413 coastal.info@noaa.gov https://coast.noaa.gov WWW:LINK-1.0-http--link NOAA Office for Coastal Management Website NOAA Office for Coastal Management Home Page information pointOfContact NOAA Office for Coastal Management (843) 740-1202 2234 South Hobson Ave Charleston SC 29405-2413 coastal.info@noaa.gov https://coast.noaa.gov WWW:LINK-1.0-http--link NOAA Office for Coastal Management Website NOAA Office for Coastal Management Home Page information custodian asNeeded https://coast.noaa.gov/data/Images/Collections/BenthicCover_thumbnail.jpg Sample of benthic cover data JPEG EARTH SCIENCE > BIOSPHERE > ECOSYSTEMS > MARINE ECOSYSTEMS > BENTHIC EARTH SCIENCE > BIOSPHERE > ECOSYSTEMS > MARINE ECOSYSTEMS > COASTAL EARTH SCIENCE > BIOSPHERE > ECOSYSTEMS > MARINE ECOSYSTEMS > ESTUARY theme Global Change Master Directory (GCMD) Science Keywords 17.0 CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > MAINE place Global Change Master Directory (GCMD) Location Keywords 20.8 Aquatic Benthic CMECS Coastal and Marine Ecological Classification Standard Eelgrass Environmental Monitoring Habitat OCM Benthic Habitat Mapping SAV Seagrass Spill Substrate Component Subtidal theme Casco Bay Coastal Maine Englishman Bay Frenchman Bay Penobscot Bay place DOC/NOAA/NOS/OCM > Office of Coastal Management, National Ocean Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

The vector polygon data was loaded into a field PC and displayed in ArcView software. A tracking software allowed the analyst to travel to specific points in the data with precision and to check the type of habitat in the field. Sample sites were selected based on their location and distribution along the coast. No empirical accuracy statistics were generated. Horizontal Positional Accuracy Horizontal accuracy meets national map accuracy standards. This was one of the most important factors in the initial field visit. Vertical Positional Accuracy Vertical accuracy was not tested. Completeness Report All SAV habitat interpretable from aerial imagery was mapped. No gaps exist in the geographic distribution of the data. Conceptual Consistency Following interpretation and digitization, a Arc format polygon coverage was produced using the BUILD commands. An editing process was also conducted to ensure proper polygon labeling and closure. Aerial photography acquisition Conventional color (Kodak Aerochrome 2448) film was acquired over the Maine coast at a nominal scale of 1:12,000. The coast was flown in an incremental fashion in 1993, 1994, 1995, 1996, and 1997. The film was flown according to the environmental parameters recommended in the C-CAP protocol. The mission specifications included 60% endlap and 30% sidelap for adjacent lines. A 153mm color corrected lens and Wild RC10 camera were used to collect the imagery.Process Date Range is 1993-1997 1997-01-01T00:00:00 Photo-Interpretation: The duplicated film diapositives were interpreted monoscopically on a large-format light table. SAV habitat was annotated on acetate overlays attached to the film. The habitat was assigned to 1 of four density classes based on percent ground coverage by actual eelgrass. The photography was interpreted by a skilled analyst who is very familiar with the local environment. GPS controlled field work was used to develop signatures suitable form mapping.Process Date Range is 1993-1997 1997-01-01T00:00:00 Data Vectorization: At the conclusion of the interpretation process, the diapositives were with overlays attached were placed on the light table below mylar USGS 7.5 minute quads. The photos were manually fitted to the USGS map and the habitat polygons were transferred to the quad mylars. Then the annotated mylar was scanned and an automated vectorization software was used to capture the linework as ESRI vectors. These vectors were manually edited and a polygon coverage was built using ArcInfo software. The benthic data is classified according to the System for Classification of Habitats in Estuarine and Marine Environments (SCHEME). This system is fully described in "Development of a System for Classification of Habitats in Estuarine and Marine Environments (SCHEME) for Florida, Report to U.S. EPA - Gulf of Mexico Program, Florida Fish and Wildlife Conservation Commission, Florida Marine Research Institute. Review Draft 12/04/02."Process Date Range is 1993-1997 1997-01-01T00:00:00 The data were converted from a single ESRI polygon shapefile classified according to the System for Classifying Habitats in Estuarine and Marine Environments (SCHEME) to the Coastal and Marine Ecological Classification Standard (CMECS) 2012 format (which can be found at https://coast.noaa.gov/digitalcoast/tools/cmecs-crosswalk) which produces separate geoform, substrate, and substrate feature layers from the original input benthic habitat dataset. This substrate feature layer contains CMECS substrate component attributes where an "Equal" or "Nearly Equal" SCHEME value was present in the original data. Polygons for which no substrate information was present have been removed. No other changes to the original polygon boundaries or any other alterations of the original SCHEME data were made during this process. 2015-01-01T00:00:00 Source Contribution: The aerial photography was used to identify and delineate SAV habitat.
