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 2014, 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 2014 and the Western half will be collected in Spring 2015. 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 2014 is jurisdiction based and is 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> |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>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. Pursuant to Section 54.1-402, paragraph C of the Code of Virginia, which is quoted below, this data may not be used for purposes listed in said paragraph C, since the data was not created, nor is it maintained under the supervision of a licensed land surveyor. C. Persons utilizing photogrammetric methods or similar remote sensing technology shall not be required to be licensed as a land surveyor pursuant to subsection B of § 54.1-404 or 54.1-406 to: (i) determine topography or contours, or to depict physical improvements, provided such maps or other documents shall not be used for the design, modification, or construction of improvements to real property or for flood plain determination, or (ii) graphically show existing property lines and boundaries on maps or other documents provided such depicted property lines and boundaries shall only be used for general information. Any determination of topography or contours, or depiction of physical improvements, utilizing photogrammetric methods or similar remote sensing technology by persons not licensed as a land surveyor pursuant to § 54.1-406 shall not show any property monumentation or property metes and bounds, nor provide any measurement showing the relationship of any physical improvements to any property line or boundary. Any person not licensed pursuant to subsection B of § 54.1-404 or 54.1-406 preparing documentation pursuant to subsection C of § 54.1-402 shall note the following on such documentation: "Any determination of topography or contours, or any depiction of physical improvements, property lines or boundaries is for general information only and shall not be used for the design, modification, or construction of improvements to real property or for flood plain determination. 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".</SPAN></P></DIV></DIV></DIV> |
