Name: NOAA Seaside Oyster Mapping Patch Reefs

Display Field: SUBTIDAL_O

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: These data are part of a comprehensive survey to describe and quantify oyster habitat and the oyster population on the Seaside of Virginia's Eastern Shore. Overall, we have included aquaculture, restoration and traditional natural reef structure in addition to other habitats: marsh and flats of varying tidal inundation regimes and manmade shoreline. The specific data in this shapefile represent isolated patch and finge reef features as polylgons. Polygons were digitized based on Virginia Base Map Program 1-m resolution aerial images (2002 & 2007). Aerials overflights were undertaken to evaluate the presence of reefs that were suspected based on these images. Companion datasets for oyster habitat polygons modified from National Wetlands Inventory and manmade shoreline data are available.
