Abstract:
The US Department of Agriculture - Farm Services Agency (USDA-FSA) NAIP program is designed to acquire 4-band digital ortho imagery from airborne and/or space-based platforms during the agricultural growing seasons in the U.S. This Emergency declaration from October - December 2021 NAIP product provides 30 cm ground sample distance (GSD) ortho imagery rectified to a horizontal accuracy of within +/- 4 meters to true ground at a 95% confidence level. The tiling format of NAIP imagery is based on a 3.75' x 3.75' quarter quadrangle with a 300 pixel buffer on all four sides. NAIP quarter quads are formatted to the UTM coordinate system using NAD83 Zones 15 (west) and 16 (east). NAIP imagery may contain as much as 10% cloud cover per tile. The county files were generated by compressing NAIP quarter quadrangle tiles that cover a county. MrSID compression, with mosaic option, was used. Target values for the compression ratio are 60:1.
