vector_DBO_Contour

Sanborn Map Co. February 2007 vector_DBO_Contour_2ft vector digital data withheld vector_DBO_Contour_2ft These 2' contours were produced as part of the VGIN mapping project executed in 2006 and 2007. Contours were provided to jurisdictions who chose to use the upgrade option for contour generation. The contours are provided in Personal Geodatabase format. Due to size limitations, a jurisdiction may contain more than one GeoDatabase. The aerial photography and creation of the subsequent contour data was executed to capture the existing ground conditions at a specific point in time for the purpose of GIS analysis. A GIS is a system of computer software, hardware, and data that allows a user to manipulate, analyze, and present information that is tied to a spatial location. GIS technology is used in scientific investigations, resource management, development planning, and many other applications that require analysis of spatial data. VGIN sub-contracted with the Sanborn Map Company to execute a Statewide mapping contract in the years 2006 and 2007. This contract updated and enhanced the existing 2002 map data. The Virginia Geographic Information Network (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. en The analog aerial photography was collected at 1"=600' scale and flown in Spring 2006 and 2007. The aerial photography was controlled with strategic photo-identifiable ground control points. The ground control points were referenced to a Statewide adjusted Network in North American Datum 1983; Virginia State Plane North. The film was scanned at 14 microns and the aerotriangulation was executed using Zeiss ISAT software. The accuracy of the aerotriangulation data supports 1"=100' mapping and the generation of 2' contours. The Digital Terrain Model (DTM) and subsequent Triangular Irregular Network (TIN) used to the interpolate the contours was photogrammetrically stereo-compiled using fully manual methods to collect masspoints and breaklines. The data was initially compiled in tile (2,500' X 2,500') tile format and seamlessly merged together into GeoDatabase format for final delivery.
