  1. 2008 NAIP Orthoimagery Update Chris Cialek MN Land Management Information Center May 7, 2008

  2. Agreement • Shared-funding agreement to provide state coverage of color digital aerial photographs in 2008 • Brokered through the USDA’s Farm Service Agency (FSA) as part of its National Agriculture Imagery Program (NAIP)  • Eight state agencies are helping to provide state’s share to fund the project

  3. Product Specifications • Full statewide coverage • 1-meter resolution (options may exist for higher resolution data cost-sharing partnerships) • Digital, four band camera: red, green, blue, near-infrared (NIR) • Orthorectification using ground control coordinated by MnDOT • Two products will be delivered: • Compressed county mosaics • Natural color (no NIR in this format) • JPEG2000 format • Delivery likely to begin in September 2008 • Uncompressed quarter-quadrangle files • Four bands: red, green, blue and NIR • GeoTIFF format • Delivered as quality-control is completed, likely during the first quarter of 2009

  4. Control Targets • MnDOT establishing control point network to assure accuracy • Contributors: • MnDOT >100 points • 80 counties ~300 points (11 completed) • Accuracy • Contracted: 6 meters • Anticipated (MnDOT): 4-5 meters

  7. Recent Developments • FSA will allow early flights over six northeastern counties – Cook, Lake, St. Louis, Carlton, Koochiching and Itasca – in hopes of collecting leaf-off imagery.  Weather conditions will largely dictate how successful this effort will be.  • In addition to providing leaf-off orthoimagery for the Arrowhead, SURDEX is considering flying the region at a lower elevation to produce two-foot resolution orthoimagery, in addition to the federally-contracted one-meter product.  Incremental cost of providing the higher resolution product is about $15.00 per square mile.  • If you think your county or municipality might be interested in partnering in this higher resolution “buy-up”, or if you have questions about the project, please contact Minnesota’s NAIP state liaison, Chris Cialek, as soon as possible.
