The National Agriculture Imagery Program (NAIP) acquires aerial imagery during the agricultural growing seasons in the continental U.S. A primary goal of the NAIP program is to make digital ortho photography available to governmental agencies and the public within a year of acquisition. NAIP projects are contracted each year based upon available funding and the FSA imagery acquisition cycle. Beginning in 2003, NAIP was acquired on a 5-year cycle. 2008 was a transition year, and a three-year cycle began in 2009.
NAIP 2011 program maintained the significant additions to data handling as compared to the years 2003-2007. Adding “Inland lakes water quarter quads” to state coverages, and dropping JPEG2000 format, and offering Compressed County Mosaics (CCMS) with absolute Horizontal Accuracy Specifications, for example. Terratracer offers single delivery on portable hard disk drives nationwide.
NAIP is administered by the USDA's Farm Service Agency (FSA) through the Aerial Photography Field Office in Salt Lake City. This "leaf-on" imagery is used as a base layer for GIS programs in FSA's County Service Centers, and is used to maintain the Common Land Unit (CLU) boundaries.
