The 2008 NAIP program provided data as quarter quadrangle tiles in JPEG2000 uncompressed format and as county mosaics in compressed (15:1 target compression) JPEG 2000 format. The FSA created the compressed county mosaic product to provide timely information for the FSA compliance program. The 2008 NAIP dataset includes polygons (shapefile format) delineating the seam boundaries between acquired imagery used in the creation of the quarter quadrangle images and the county mosaics. Users can use these polygons as a tool to determine the image source date for each portion of the dataset. The metadata for each quarter quad image includes the source date of the image.
The 2008 NAIP program implemented two major changes from previous years: terrain correction to true ground position and acquisition of four band imagery (red, green, blue, and near infrared frequencies). All images were rectified to true ground control points, rather than existing imagery as in previous years to improve accuracy. Mapping personnel worked closely with NAIP staff to acquire ground control points used for quality assurance assessments. Users may view the 4 band imagery either as natural color or color infrared images by changing the band display options. The cost of adding the fourth band to the deliverable product was not significantly more than the cost of a 3 band image acquisition and provided users with more information.
