The collection of aerial photography, update of the DTM surface and production of orthophotography was executed to capture the existing ground conditions at a specific point in time for the purpose of GIS analysis. Orthophotography along with DTM 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. |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>In the spring of 2009, 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 the Sanborn Map Company to provide aerial data acquisition, ground control, aerial triangulation and development of statewide DTM and digital orthophotography data. The Virginia Base Mapping Program (VBMP) update project is divided into two collection phases: the Eastern half was collected in Spring 2009 and the Western half was collected inSpring 2011. Ortho products are 1-foot resolution statewide ortho-imagery with upgrades to 6-inch resolution tiles and 3-inch resolution tiles in various regions within the project area. All data acquired in 2011 is jurisdiction based and is mostly in the western half of the state with upgrades requested in the eastern half of the state. 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.</SPAN></P></DIV></DIV></DIV> |

This VBMP data has been developed using procedures designed to produce data to comply with the Model Virginia Map Accuracy Standards (1992) and is intended for use at 1" = 100' or 1" = 200' scale. It is requested that the Commonwealth of Virginia be cited for any use of the orthophotography as follows: "Imagery Courtesy of the Commonwealth of Virginia". |
