Presentation Transcript

  1. 2009-2012 Update Cycle • RFP Closed on September 24th • Image Capture Split Between 2009 and 2011 • Eastern Half of State Will Be Captured during 2009 and Western Half Will Be Captured during 2011 • Digital Capture • Faster Delivery – Within 6 Months of Acquisition • Multiple Upgrade Options • Requested upgrades include resolution upgrades, contours, planimetrics, true orthophotography, color infrared, and off year flights • Vendors were encouraged to submit other upgrade options

  2. 2009/2011 Flight Areas

  3. City of Richmond Orthophoto

  4. City of Richmond TRUE Orthophoto

  5. 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

  6. 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

  7. NAIP Deliverables • Initial Delivery – County Mosaics • Preliminary Format with Limited QA/QC • JPEG 2000 Format • Entire State Has Been Delivered • Final Delivery – Quarter Quadrangles • Full QA/QC • GeoTiff Format • Delivery on or before September 30, 2009

  8. NAIP Distribution • Available Soon for Download through the VGIN Metadata Portal at http://gisdata.virginia.gov/ • Radford University Will Also Host Data for Download at http://geoserve.asp.radford.edu/

  9. 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

  10. Using NAIP – Urban Tree Canopy Analysis Classified Image 2008 NAIP Image Near-infrared (Band 4) enhances vegetation

  11. Using NAIP – Change Detection 2007 VBMP 2008 NAIP

  12. Using NAIP – Water Feature Detection True Color Color Infrared Infrared Only
