Description:This data set contains imagery from the National
Agriculture Imagery Program (NAIP). The NAIP
acquires digital ortho imagery during the
agricultural growing seasons in the continental U.S..
A primary goal of the NAIP program is to enable
availability of ortho imagery within one year of
acquisition. The NAIP provides two main products: 1
meter ground sample distance (GSD) ortho imagery
rectified to a horizontal accuracy within +/- 5 meters
of reference digital ortho quarter quads (DOQQ's) from
the National Digital Ortho Program (NDOP) or from the
National Agriculture Imagery Program (NAIP); 1 meter
or 60cm GSD ortho imagery rectified within +/- 6
meters to true ground. 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. The NAIP imagery is
formatted to the UTM coordinate system using the North
American Datum of 1983 (NAD83). The NAIP imagery may
contain as much as 10% cloud cover per tile. This file
was generated by compressing NAIP imagery that covers
the county extent. Two types of compression may be
used for NAIP imagery: MrSID and JPEG 2000. The target
value for the compression ratio is 15:1 for the 1 meter
imagery and 60:1 for the 60cm imagery.
