Abstract:
This data set contains imagery from the National Agriculture
Imagery Program (NAIP).  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. NAIP provides two
main products: 1 meter ground sample distance (GSD) ortho
imagery rectified to a horizontal accuracy of 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 GSD ortho
imagery rectified to 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 meter buffer on all four sides.
NAIP quarter quads are formatted to the UTM coordinate system
using NAD83.  NAIP imagery may contain as much as 10% cloud
cover per tile.  This file was generated by compressing NAIP
quarter quadrangle tiles that cover a county.  Two types of
compression may be used for 2008 NAIP imagery: MrSID and JPEG
2000. Target values for the compression ratio are (15:1).
Purpose:
NAIP imagery is available for distribution within 60 days of the end of a flying season and is intended to provide current information of agricultural conditions in support of USDA farm programs. For USDA Farm Service Agency, the 1 meter GSD product provides an ortho image base for Common Land Unit boundaries and other data sets. The 1 meter NAIP imagery is generally acquired in projects covering full states in cooperation with state government and other federal agencies who use the imagery for a variety of purposes including land use planning and natural resource assessment. With an annual cycle, NAIP is also used for disaster response often providing the most current pre-event imagery.

Use_Constraints:
Imagery may be replaced to address defects found in a small
number of products through quality assurance processes.  Imagery
containing defects that require the acquisition of new imagery,
such as excessive cloud cover, specular reflectance, etc., will
not be replaced within a NAIP project year.

Process_Description:
Once DOQQ tiles were completed for a county, images were
color balanced in INPHO Orthovista. For counties that are
split by UTM zone lines, re-projection was completed with
Global Mapper. After individual images are adjusted, the
DOQQs are transformed into compressed county mosaic (CCM)
using MrSid 6.1 or 7.0 from Lizard Tech. Shape files and
metadata were prepared in ArcMap 9.2. CCMs were reviewed
in Erdas Imagine or ESRI ArcMap. CDs/DVDs were burned
after final QC of the CCMs.
