Service Description: See http://www.vita.virginia.gov/isp/default.aspx?id=12118 for a full description of this and other VGIN aerial imagery. On January 29, 2002, the Commonwealth contracted with VARGIS LLC. of Herndon, Virginia to produce full color, leaf-off, digital orthophotography for the entire land base of Virginia. The imagery was developed at one of 3 scales: 1:4,800 scale (2' resolution) in rural areas 1:2,400 scale (1' resolution) in urban and suburban areas and 1:1,200 scale (1/2' resolution) in areas where localities chose the option to purchase higher accuracy product. The extent of each scale was initially determined by evaluating population and housing densities to determine those areas that would be flown for 1:4,800 and 1:2,400 scale imagery. Each locality was then offered the opportunity to upgrade the scale of imagery in their locality by providing the cost difference between what the program would have paid and the cost of their optional upgrade. 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 Countywide TINs Digital Elevation Models in ESRI Grid format for Virginia State Plane North and South zones Raw image scans
