Item Identification

Title: 2017 Florida NAIP 4-Band 8 Bit Imagery
Status: Completed
Publication Date: 2015-12-18
Abstract:

This data set contains polygons delineating the seamline

boundaries of imagery acquired as part of the

National Agriculture Imagery Program (NAIP), and used in

the creation of DOQQs and compressed county mosaics

(CCM). These seam polygons can be used as a

tool in determining the image source and date of each

portion of the DOQQ or the CCM. The NAIP acquires

4 band digital ortho imagery from airborne and/or space

based platforms during the agricultural growing seasons

in the 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 or 1/2 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).

Purpose:

The NAIP imagery is typically 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 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. The NAIP is

also used for disaster response often providing the most

current pre-event imagery.

Lineage

Process Steps

Process Step 1

CC ID: 1313584
Description:

The imagery was collected using the following digital sensors:

Leica ADS-100 (Serial Number 10541)

Leica ADS-100 (Serial Number 10548)

Leica ADS-100 (Serial Number 10564)

with Flight and Sensor Control Management

System (FCMS) firmware 4.54.

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 16,500 ft above mean terrain

(tail number: AC90 N910FC)

(tail number: C441 N441CJ)

(tail number: C441 N441MD)

With these flying heights, there is a 23% sidelap,

giving the collected data nominal ground sampling distance

of 0.40 meters at 16,500.

Based-upon the CCD Array configuration present in

the ADS digital sensor, imagery for each flight

line is 20,000-pixels in width. Red, Green, Blue,

Near-Infrared and Panchromatic image bands were collected.

The ADS 100 has the following band specifications:

Red 619-651

Green 525-585

Blue 435-495

Near Infrared 808-882

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 XPro software.

Airborne GPS / IMU data was post-processed using INYS,

PosPac and/or TerraPos software and reviewed to ensure

sufficient accuracy for project requirements.

Using Inpho 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.

Process Step 2

CC ID: 1313585
Description:

Aero triangulation blocks were defined primarily by order of

acquisition and consisted of four to seventeen strips.

Image tie points providing the observations for the least

squares bundle adjustment were selected from the images

using an auto correlation algorithm. Photogrammetric control

points consisted of photo identifiable control points,

collected using GPS field survey techniques. The control

points were loaded in to a softcopy workstation and measured

in the acquired image strips. A least squares bundle

adjustment of image pass points, control points and the

ABGPS was performed to develop an aero triangulation

solution for each block using Pictovera software.

Upon final bundle adjustment, the triangulated strips were

ortho-rectified to the digital elevation model (DEM) The most

recent USGS 10 meter DEMs were used in the rectification

process.

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 ADS 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 OrthoVista Radiometrix software. A constant

stretch was defined for each image collection period, and

then strip by strip adjustments were made as needed to

account for changes in sun angle and azimuth during the

collection period. Strip adjustments were also made to

match the strips histograms as closely as possible to

APFO specified histogram metrics and color balance

requirements. Automated balancing algorithms were applied

to account for bi- directional reflectance as a final step

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

mosaicked using manual seam line generation in OrthoVista.

APFO specified DOQQs were extracted from the final mosaic in

GeoTIFF format. 4-Band DOQQs were produced and 3-Band RGB

CCMs were created. DOQQs corresponding to an individual CCM

were reviewed for overall color balance within the CCM.

Local corrections were made where necessary to ensure

uniformity within the CCM. In the case of DOQQs occurring

in more than one CCM, a separate version of the image was

generated and balanced for each CCM it occurred in. The

color balanced DOQQs were then compressed to MrSID

Generation 3 format at 15:1 compression ratio to create a

composite CCM.
