资源简介:
This data set contains imagery from the National Agriculture
Imagery Program (NAIP). The NAIP program is administered by
USDA FSA and has been established to support two main FSA
strategic goals centered on agricultural production.
These are, increase stewardship of America's natural resources
while enhancing the environment, and to ensure commodities
are procured and distributed effectively and efficiently to
increase food security. The NAIP program supports these goals by
acquiring and providing orthoimagery that has been collected
during the agricultural growing season in the U.S. The NAIP
orthoimagery is tailored to meet FSA requirements and is a
fundamental tool used to support FSA farm and conservation
programs. Orthoimagery provides an effective, intuitive
means of communication about farm program administration
between FSA and stakeholders.
New technology and innovation is identified by fostering and
maintaining a relationship with vendors and government
partners, and by keeping pace with the broader geospatial
community. As a result of these efforts the NAIP program
provides three main products: DOQQ tiles,
Compressed County Mosaics (CCM), and Seamline shape files
The Contract specifications for NAIP imagery have changed
over time reflecting agency requirements and improving
technologies. These changes include image resolution,
horizontal accuracy, coverage area, and number of bands.
In general, flying seasons are established by FSA and are
targeted for peak crop growing conditions. The NAIP
acquisition cycle is based on a minimum 3 year refresh of base
ortho imagery. The tiling format of the 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 the North American Datum of 1983.
NAIP imagery may contain as much as 10% cloud cover per tile.
