Title: 2014 Coastal Illinois NAIP Digital Ortho Photo Imagery
Short Name: 2014_illinois_naip
Status: Completed
Publication Date: 2015-02-05
Abstract:

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 ortho imagery that has been collected

during the agricultural growing season in the U.S. The NAIP

ortho imagery is tailored to meet FSA requirements and is a

fundamental tool used to support FSA farm and conservation

programs. Ortho imagery 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.

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 and 1/2 meter

GSD product provides an ortho image base for Common Land Unit

boundaries and other data sets. The 1 meter and 1/2 meter NAIP

imagery is generally acquired in projects covering full states in

cooperation with state government and other federal agencies that

use the imagery for a variety of purposes including land use

planning and natural resource assessment. The NAIP is also used

for disaster response. While suitable for a variety of uses,

prior to 2007 the 2 meter GSD NAIP imagery was primarily intended

to assess "crop condition and compliance" to USDA farm program

conditions. The 2 meter imagery was generally acquired only

for agricultural areas within state projects.

Data Quality

Horizontal Positional Accuracy:

NAIP horizontal accuracy specifications have evolved over

the life of the program. From 2003 to 2004 the

specifications were as follows: 1-meter GSD imagery was

to match within 3-meters, and 2-meter GSD to match within 10

meters of reference imagery. For 2005 the 1-meter GSD

specification was changed to 5 meters matching the reference

imagery. In 2006 a pilot project was performed using true

ground specifications rather than reference imagery. All

states used the same specifications as 2005 except Utah,

which required a match of +/- 6 meters to true ground.

In 2007 all specifications were the same as 2006 except

Arizona used true ground specifications and all other states

used reference imagery. In 2008 and subsequent years

no 2-meter GSD imagery was acquired and all specifications

were the same as 2007 except approximately half of the

states acquired used true ground specifications and the

other half used reference imagery. The 2008 states that

used absolute ground control where; Indiana, Minnesota,

New Hampshire, North Carolina, Texas, Vermont, and Virginia.

From 2009 to present all NAIP imagery acquisitions used

the +/- 6 meters to ground specification.

Description:

CCM Production Process Description

USDA FSA APFO NAIP Program 2014

State: Illinois

The imagery was collected using the following digital sensors:

Microsoft UltraCam Eagle (Serial Number 00817310)

Microsoft UltraCam Eagle (Serial Number 50617043)

with an 80mm lens and TrackAir firmware 4.08.

Cameras are calibrated radiometrically and geometrically

by the manufacturer and are all certified by the USGS.

Collection was performed using a combination of the

following twin-engine aircraft:

Turbines flying at 28,000 ft above mean terrain

(tail numbers: C441 N87WS, C441 N441MD)

With these flying heights, there is a planned

30% sidelap and a 60% forward overlap. The

collected data nominal ground sampling distance

of 0.50 meters at 28,000. Based-upon the

CCD Array configuration present in the UltraCam

Eagle digital sensor, imagery for each frame

line is 20,010 by 13,080 pixels. Red, Green, Blue,

Near-Infrared and Panchromatic image bands were collected.

The UCE has the following band specifications:

Pan 380-725

Red 585-740

Green 485-720

Blue 395-605

Near Infrared 685-1000

all values are in nanometers

Collected data was downloaded to portable hard drives and

shipped to the processing facility daily. Raw flight data

was extracted from external data drives using UltraMap

software. Airborne GPS / IMU data was post-processed using

POSMMS software and reviewed to ensure

sufficient accuracy for project requirements.

Using OrthoPro software, planar rectified images were

generated from the collected data for use in image quality

review. The planar rectified images were generated at five

meter resolution using a two standard deviation histogram

stretch. Factors considered during this review included but

were not limited to the presence of smoke and/or cloud

cover, contrails, light conditions, sun glint and any sensor

or hardware-related issues that potentially could result in

faulty data. When necessary, image strips identified as not

meeting image quality specifications were re-flown to obtain

suitable imagery.

External Orientation (EO) values were calculated from

airborne trajectory data and exposure timing data in

Applanix POSMMS. Calculated EO's were applied to image

frames in Intergraph GeoMedia OrthoPro, and the oriented

image frames were orthorectified to the USGS 10-meter NED.

Positional accuracy was reviewed in the rectified imagery by

visually verifying the horizontal positioning of the known

photo-identifiable survey locations using ArcGIS software.

The red, green, blue, and infrared bands were combined to

generate a final ortho-rectified image strip. The UltraCam

sensor collects twelve bit image data which requires

radiometric adjustment for output in standard eight

bit image channels. The ortho-rectified image strips

were produced with the full 12 bit data range, allowing

radiometric adjustment to 8 bit range to be performed

on a strip by strip basis during the final

mosaicking steps.

The 12 bit data range was adjusted for display in standard

eight bit image channels by defining a piecewise histogram

stretch using UltraMap Radiometry software. A constant

stretch was defined for each image collection period, and

then per image adjustments were made as needed to

account for changes in sun angle and azimuth during the

collection period. Per mission were also made to

match mission statistics as closely as possible to

APFO specified histogram metrics and color balance

requirements. Automated balancing algorithms were applied

to account for image hotspots as a final step

before the conversion to 8 bit data range. The imagery was

mosaicked using automatic seam line generation in Intergraph

GeoMedia OrthoPro.
