Contours - Western

In the spring of 2017, the Commonwealth of Virginia, through the Virginia Geographic Information Network Division (herein referred to as VGIN) of the Virginia Information Technologies Agency (VITA) contracted with Fugro Geospatial, Inc. to provide aerial data acquisition, ground control, aerial triangulation and development of statewide ortho quality DEM and digital orthophotography data. The Virginia Base Mapping Program (VBMP) update project is divided into three collection phases: In 2017, Fugro flew the eastern third of Virginia at one foot resolution, with options for localities and other interested parties to upgrade resolution or purchase other optional products through the state contract. The middle third of Virginia will be flown in 2018 and the western third in 2019. Ortho products are 1-foot resolution statewide with upgrades to 6-inch resolution tiles and 3-inch resolution tiles in various regions within the project area. The Virginia Base Mapping project encompasses the entire land area of the Commonwealth of Virginia over 4 years. The State boundary is buffered by 1000'. Coastal areas of the State bordering the Atlantic Ocean or the Chesapeake Bay are buffered by 1000' or the extent of man-made features extending from shore. This metadata record describes the generation of new Digital Terrain Model (DTM) and contours generated at 2-foot intervals. All products are being delivered in the North American Datum of 1983 (1986), State Plane Virginia North. The vertical datum was the North American Vertical Datum of 1988 (NAVD88) using GEOID12B. Lines of equal elevation on a surface. An imaginary line on the ground, all points of which are at the same elevation above or below a specified reference surface (vertical datum)
Commuter Lots

This point data layer portays commuter lots within Prince William County with associated attributes that include name, spaces, address, nearest intersection, bicycle accommodations, slug line availability, transit service, lot manager and alternate name(s). A combination of sources have been used to compile this data. The owner/servicer's publicly available digital information, as well as publicly available digital imagery, were the primary sources utilized. When the owner's and servicer's data didn't match, the owner's information was used. For some extended attributes and private lots, the Virginia Department of Transportation (VDOT) website and publicly available slug line websites were utlized.

The collection of aerial photography and production of an ortho quality DEM and orthophotography was executed to capture the existing ground conditions at a specific point in time for the purpose of GIS analysis. Orthophotography along with DEM data typically provides an accurate base for digitally representing geographic features upon which a GIS is built. The Virginia Geographic Information Network Division (VGIN) is the lead public agency in the Commonwealth for spatial data and GIS. VGIN's mission is to facilitate the cost-effective development and use of spatial data, GIS, and related technologies in organizations throughout the Commonwealth. Quantico Marine Corp Base (QMCB) area within Prince William County was excluded from 2017 Contour project. This area digital imagery was flown at 12 inch pixel resolution. The remainder of Prince William County was captured at a 6-inch resolution. The Contour and other associated data was created utilizing the 6-inch resolution. A Breakline is a line used to connect data representing a distinct surface feature, like a ridge line, edge of pavement, toe of a slope, centreline of a road, or flowline of a ditch or stream. A breakline is a linear feature that describes a change in the smoothness or continuity of a surface.

Land Cover 2017

A Green Infrastructure map county of Prince William, VA was developed to provide quantification of canopy and associated data for environmental monitoring. Digital aerial imagery, collected for the National Agriculture Imagery (NAIP) program at 1 meter resolution was classified to a Green Infrastructure Level 1 classification scheme with the following classes: 1) Non Woody Vegetation, 2)Woody Vegetation, 3) Impervious, 4) Water and 5) Bare Soil. The image was classified using Classification and Regression Tree techniques (CART analysis) and raster modeling. The classification accuracy assessment gave an overall accuracy of 95.25%This 2012 update is the result of a change detection process which buillt on the original 2008 classification. Changed areas were updated, and several other classification scheme changes were made, such as the reclassification of pools as impervious surfaces.

This data layer contains polygon features representing the approximate locations of dam break inundation zones and special flood hazard areas (Floodplains and Floodways). It was created to provide users the ability to overlay these features onto the parcel boundary layer.The dam break inundation zone layer provided by the Virginia Department of Conservation. The special flood hazard area layer was provided by Federal Emergency Management Agency (FEMA). Users should consult these agencies for legal inundation zone and special flood hazard area boundaries.
Resource Protection Areas (RPA)

This data layer contains polygon features representing the approximate locations of Resource Protection Areas located within Prince William County, Virginia. RPAs include the land area within 100 feet of a perennial stream bank or edge of wetlands adjacent to the perennial stream. RPA areas are protected under state law and local ordinances. In general, no development, land disturbance, or vegetation removal is allowed in an RPA. RPAs were designated along all perennial streams in the County. The layer was derived from PASA (Preservation Area Site Assessment) studies that have been approved by Watershed Management Branch, Environmental Management Division, Department of Public Works.
VBMP Tile Grid - South 3-inch (50 Scale)

Tile polygons used by the Virginia Base Mapping Program (VBMP) for the production, storage and delivery of base map data such as as orthoimagery, digital terrain model and lidar data. Grids exist for both the North and South Virginia State Plane Zones, and at scales of 1 in = 200 ft (1-ft pixel imagery), 1 in = 100 ft (6-in pixel imagery),and 1 in = 50 ft (3-in pixel imagery). The tile nest within the tiles at larger scale. Please note that not all products are available at all scales for each VBMP project year.
Perennial Streams Shapefile

The Code of Virginia, §62.1-44.123, states: “Any person who owns property in the Chesapeake Bay watershed on which 20 or more bovines are pastured shall install and maintain stream exclusion practices sufficient to exclude all such bovines from any perennial stream in the watershed.” The Department of Conservation and Recreation Perennial Stream dataset has been created in accordance with §62.1-44.122 of the Code of Virginia to determine compliance with §62.144-123 of the Code of Virginia. The dataset adheres to all requirements established by the Virginia Soil and Water Conservation Board (Board) and the Department of Conservation and Recreation (Department) guidance document entitled Virginia Soil and Water Conservation Board Guidance Document on the Methodology for Identifying Perennial Streams. The Board and the Department reserve the right to utilize the data for other purposes as approved by the Board or Department.
Virginia COVA Agency Facilities

This layer began as part of the Virginia.gov data development project in 2008-2009. VGIN was tasked to generate cartography and data for a specific application for location of Virginia state agency locations in relation to the project. In 2010, The State Broadband Data Development Program (SBDD) Community Anchor Institutions (CAI) dataset leveraged much of that data and catalogued broadband service to a specific feature. The points have since been checked and updated annually as part of the Virginia Landmark dataset. The data is matched to the Virginia Address Point dataset. There are numerous data sources associated to the point. The general development methodology is as follows: The facility data was extracted and geocoded to the VGIN Geocoding service. If results were positioned on the Road Centerline by the RCL locator, those features were subsequently updated and moved to match the address point in the data layer. Unmatched results were added to the map. Non-spatial address location data is harvested into a spreadsheet by the source agency and checked against the GIS data annually. Fields for Landmark Name, Place Type, Source, and Source Type can be used to differentiate specific data as stored in the dataset.
