Virginia Partnership with USDA NAIP• 2008 Imagery Acquisition by USDA
– “leaf on” summer collection– One meter resolution– True color – ~85% coverage for Virginia
• With Partnership– 4 Band color (true color and near infrared)– Improved Accuracy using VBMP Control Pts.– 100% coverage

Virginia Partnership with USDA NAIP• Total NAIP Budget for VA: $740,296• Total provided by Virginia:
– VA Department of Forestry: $25,000– VA Department of Transportation: $25,000– VA Information Technologies Agency/VGIN:
$40,000 plus all VBMP Control Points ($25,000 value)
– Total: $90,000 plus control points
• Without partnership, VA would not have been captured in 2008 due to USDA budget cutbacks

Using NAIP – Urban Tree Canopy Analysis
Virginia Department of Forestry• High resolution landcover is integrated with
planimetric datasets, such as buildings and roads, to determine the existing Urban Tree Canopy and possible Urban Tree Canopy
• Leaf on, infra-red photography is essential to accurately identify tree crowns (infra-red NAIP provides this)
• Collaboration with communities: VDOF provides landcover classification and advice, communities provide GIS data and goal setting process
