Description: This is a hybrid of the 2014 Virginia Administrative Boundaries - county (VGIN) and the 2004 County Boundaries (DCR) with a portion of the Chesapeake Bay removed. VA_COUNTY represents the best available city and county boundary information to VGIN.VGIN initially sought to develop an improved locality and town boundary dataset in late 2013, spurred by response of the Virginia Administrative Boundaries Workgroup community. The feature class initially started from the locality boundaries from the Census TIGER dataset for Virginia. VGIN solicited input from localities in Virginia through the Road Centerlines data submission process as well as through public forums such as the Virginia Administrative Boundaries Workgroup and VGIN listservs. Data received were analyzed and incorporated into the VA_COUNTY feature class where locality data were a superior representation of the city or county boundary.

Description: This shapefile was generated by the Virginia Marine Resources Commission (VMRC). VMRC is responsible for siting, surveying, and creating oyster reef restoration sites in the Virginia portion of the Chesapeake Bay. GPS locations are taken on site using a combination of GPS and navigational equipment. Generally three to four sites delineate the outer edge of the reef (or proposed reef) site. These data are converted into shape files which contain polygons depicting reef boundaries.

Description: The "Baylor Survey" was conducted over a two year period begining in 1894. This massive survey located and mapped the naturally productive oyster beds, rocks, and shoals throughout Virginia's tidal waters. These Public Baylor Grounds are reserved for public shellfish harvesting and can not be leased or used for other purposes.

Description: This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the United States and its Territories. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and near shore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery. By policy, the Service also excludes certain types of "farmed wetlands" as may be defined by the Food Security Act or that do not coincide with the Cowardin et al. definition. Contact the Service's Regional Wetland Coordinator for additional information on what types of farmed wetlands are included on wetland maps. This dataset should be used in conjunction with the Wetlands Project Metadata layer, which contains project specific wetlands mapping procedures and information on dates, scales and emulsion of imagery used to map the wetlands within specific project boundaries.
