USDA-FSA-APFO Digital Ortho Mosaic

USDA_FSA_APFO Aerial Photography Field Office
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
of ortho imagery within one year of acquisition. NAIP provides
four 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); 2 meter GSD
ortho imagery rectified to within +/- 10 meters of reference
DOQQs; 1 meter GSD ortho imagery rectified to within +/- 6
meters to true ground; and, 2 meter GSD ortho imagery rectified
to within +/- 10 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. MrSID compression, with mosaic
option, was used. Target values for the compression ratio
are (15:1) and maximum number of compression levels are used.
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. 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.

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.

Direct digital capture using ZI Imageing DMC sensors flown
with 30% lateral overlap at 26,000+/- feet AMT. Download
and imagery QA/QC performed using Intergraph PPS software
suite. Inertial measurement and GPS data was collected and
processing was performed using Applanix PosPAC version 4.3
or higher, this provides both the position and orientation
of the sensor during flight. The control Exterior Orientation
file used in the ortho production was ceated from the
Applanix resulting position file. Orthorectification was
performed on the imagery on a image-by-image basis using
Intergraph Orthopro software. The imagery is then mosaiced
using both automatic and manual seam-line generation
processes to mosaic the imagery together into a seamless
product both geometrically and radiometrically. This
seamless mosaic is cut into the DOQQ tiles with a 300m
buffer. Each DOQQ is inspected for relative horizontal
accuracy with adjacent DOQQ tiles. A sample of DOQQs is
inspected for relative horizontal accuracy with the USDA
furnished data. Completed and approved DOQQs were assembled
into a countywide MrSID file; a Compressed County
Mosaic (CCM), using a compression factor of 15:1. The
countywide MrSID mosaics are edge-inspected against the
prior generation county mosaics to ensure accuracy. All
data was delivered with absolute accuracy, 1-meter Ground
Sample Distance (GSD).
