Abstract
| This data set contains natural color 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 sixty days of acquisition.
The NAIP provides 1 meter GSD ortho imagery rectified
within +/- 6 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 (plus or minus 30) pixel buffer
on all four sides. The NAIP quarter quads are formatted to
the UTM coordinate system using the North American Datum
of 1983 (NAD83). Quarter quadrangles were combined to create individual county mosaic's for Oklahoma's 77 counties and then compressed with LizardTech technology (MrSid) and made available to the public as compressed county mosaics (CCM). These MrSid CCM's were processed by the Oklahoma Office of Geographic Information to create jpeg compressed quarter quad geotiffs in the EPSG 4326 (WGS84) coordinate system. These compressed quarter-quads were further processed into 512,512 pixel tiles for distribution through the Geoserver web application, OKMaps. |

Purpose
| NAIP imagery is available for distribution
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. While suitable for a variety of uses the 2 meter
GSD NAIP imagery is primarily intended to assess crop condition
and compliance to USDA farm program conditions. The 2
meter imagery is generally acquired only for agricultural areas
within state projects. |
