  1. 2008 NAIP States Introduction Brian Vanderbilt USDA Farm Service Agency Aerial Photography Field Office brian.vanderbilt@slc.usda.gov

  2. Topics • Products and Formats • CCM Formats • 4-band • JPEG 2000 • Absolute Accuracy • Seamline Shapefiles

  3. Who’s Getting What? • 4-band & JPEG 2000 • CT, IN, KS, MN, RI, TN, TX, VA, VT • Absolute Accuracy • IN, MN, NH, NC, VA, VT, TX • Seamline Shapefile • IA, IN, KS, OK, TX, VA

  4. 4-band Imagery

  5. 4-band Imagery • Natural color is default • Band Order in ArcGIS – RGBIR • Tools, Options, Raster… • LizardTech™ MrSID compression does not currently support 4-band imagery • 2008 4-band CCMs will be compressed using JPEG 2000 • RFI was released Nov 07 asking for end user/industry input on settings • Settings were published in 2008 RFP

  6. 4-band Imagery 2007 NAIP (AZ)

  7. 4-band Imagery 2007 NAIP (AZ)

  8. Absolute Horizontal Accuracy

  9. Absolute Horizontal Accuracy • Need for absolute identified • Partners were requesting change • Dataset accuracy is better described (valuable) • Pilots conducted • 2006 (UT) • UT: 3.40m RMSE (400+ check points) • 2006 UT NAIP Absolute Accuracy Pilot Summary Report • http://www.fsa.usda.gov/Internet/FSA_File/naip06_ut_pilot_summ_rep.pdf • 2007 (AZ) • AZ: 2.87m RMSE (530 check points) • 2007 AZ NAIP Accuracy Versus MDOQ • http://www.fsa.usda.gov/Internet/FSA_File/az_absolute_cntrlpdf.pdf • Future states will be phased in • Once converted, state will not revert

  10. Absolute Horizontal Accuracy • Working with other Federal and State agencies to create a photo identifiable control database for QA check points • Will be asking for your assistance, if we haven’t already • Thanks for your efforts

  11. Seamline Shapefile

  12. Seamline Shapefile • 2007 NAIP Pilot (AZ) • Better represent image dates • Majority dates in QQ • “Look” can vary greatly by sensor

  13. Seamline Shapefile • Successful pilot was conducted in 2007 (Arizona) using ADS-40 • Expanded seamline shapefile requirements in 2008 • Test different digital camera footprints • Resolve “unknowns” before proceeding to all states

  14. ADS-40 based seamline shapefile 2007 NAIP (AZ) Seamline Shapefile 2007 NAIP (TN) Standard rectangular shapefile

  15. Seamline Shapefile

  16. 2007 NAIP Survey Results • Draft summary for review soon • Final sometime in June or July • Thank you for your participation!!!
