North Carolina Seagrass Submersed Rooted Vasculars 1990 Geodatabase

A GIS data set of polygon data interpreted from aerial photography taken by NOAA/NOS Photogrammetry Branch depicting areas of Aquatic Beds of Rooted Vascular Plants in coastal north Carolina. Predominantly submersed rooted vasculars (SRV) but including some floating rooted vasculars (FRV). The nomenclature and definitions originally developed according to the Coastal Land Cover Classification System for the NOAA Coastal Change Analysis Project (C-CAP), Journal of Coastal Research 9(3):862-872 have been crosswalked into the Florida System For Classification of Habitats in Estuarine and Marine Environments (SCHEME) to build consistency with similar NOAA developed benthic data sets.

Photointerpretation with a Wild AVIOPRET stereoscope. Photographs and data were compiled on a Bausch and Lomb stereo zoom transfer scope at a scale of 1:24,000 on USGS 7.5' topographic maps or on NOAA shoreline topographic sheets scaled to 1:24,000 (original scale 1:20,000). Data is a merge of several coverages dependent on map base, photo mission, and photographic scale.

This file geodatabase contains three feature layers corresponding to the CMECS 2012 Geoform, Substrate, and Biotic components. These layers were converted from an earlier version classified according to the System for Classifying Habitats in Estuarine and Marine Environments (SCHEME) using the CMECS Crosswalk Tool. Each feature layer has its own metadata record describing the attributes, and data development methods associated with it.
