Service Description: 2006/2007 VBMP Specifications In the spring of 2006, the Commonwealth of Virginia, through the Virginia Geographic Information Network Division (VGIN) of the Virginia Information Technologies Agency (VITA) contracted with the Sanborn Map Company to provide aerial data acquisition, ground control, aerotriangulation and development of statewide DTM and digital orthophotography. Approximately 15% of the State was acquired in the year 2006 and the balance in 2007. All data acquired in 2006 is jurisdiction based and has been delivered to VGIN. The data acquired in 2007 includes overlap along the boundaries of jurisdictions captured in the previous year 2006. This ensures each jurisdiction has full coverage from either Year 2006 or 2007, without "mixing" imagery vintage along the edge of a jurisdiction. The 2007 data is currently being delivered to VGIN and delivery should be complete sometime during late spring / early summer of 2008. During this update, the imagery was developed at one of 2 scales: 1:2,400 scale (1' resolution) over the entire Commonwealth and 1:1,200 scale (1/2' resolution) in areas where localities chose the option to purchase higher accuracy product. Each locality was then offered the opportunity to upgrade to two additional products. They could choose to add contours or building planimetrics. The resolution of the upgrades was dependent on the resolution of the orthophotography chosen. Deliverables include: Full resolution orthophotography in GeoTiff and MrSID format 1 meter resampled orthophotography in GeoTiff and MrSID format Digital Terrain Models in Microstation dgn format 2 or 4 foot contours for select areas in ESRI Personal Geodatabase format Building planimetrics for select areas in ESRI Personal Geodatabase format Raw image scans
