Title: 2006 USGS Southeast U.S. Imagery
Short Name: aerials_express
Status: Completed
Publication Date: 2006-05

Aerial imagery is a critical geospatial data component in identyfing, planning, and preparing for the protection of the US and its people. This dataset includes approximately 78,000 square miles of coverage along or near the Gulf Coast and the Atlantic coastline, terminating north of Wilmington, North Carolina. The imagery was collected in 2006 using aircraft to produce a 0.5 meter pixel resolution. It is color and ortho-rectified.

The dataset was collected to insure digital imagery coverage of the urban areas along the coastlines most prone to hurricane forces and devastation. The coverage allows all government entities an inter operable common operating picture during a critical event or in pre or post planning.

Data Quality

Horizontal Positional Accuracy:

The horizontal positional accuracy and the assurance of that accuracy depend, in part, on the accuracy of the data inputs to the rectification process. The positions of existing USGS photoidentifiable ground control were evaluated on the Geotiff image and compared with their ground values in order to determine an overall accuracy for the final Urban Area. After image coordinate measurement was completed, a radial RMSE was calculated for the entire block. This value is an estimate of the horizontal accuracy of the tile expressed in meters. Aerials Express does not warrant horizontal accuracy to exceed that of 5.0 meters at 90% (NMAS for 1:12000-scale products).; Quantitative Value: 5.0 meters, Test that produced the value: Federal Geographic Data Committee, 1998, Geospatial Positioning Accuracy Standard, Part 3, National Standard for Spatial Data Accuracy, FGDC-STD-007.3-1998

Completeness Report:

Imagery is seamless and nearly cloud free. Ocean water has been colorized to mask out most light reflections and color issues.

Conceptual Consistency:

The Photography was flown using a film Camera.

Process Steps

Process Step 1

CC ID: 668530

The production process starts when the film is received from the processing lab. The process is broken into four phases: scanning, Automatic-Triangulation, Color Balancing, Seamlines, and quality control. Scanning Much is determined in the first step of scanning. It is important that this step is done correctly in order for the remaining steps to run smoothly. It is for this reason that a ZEISS Photo Scan photogrammetric scanner is used to perform all scanning in-house. This provides complete control for both resolution and color balance at the start of the process. Automatic Triangulation and Rectification We use Intergraph's Image Station Auto-Triangulaton (ISAT) system that works hand-in-hand with IMU/ABGPS data to match photos together. It is an automated process to create automatic tie points between photos. The process uses a bundle adjustment to tighten the accuracy of the tie points. Upon good AT results, we then use a DEM to rectify the photos with Intergraph's Image Station Ortho Pro (ISOP) software. Color Balancing and Seamline Generation After rectification an overall tone balancing using ER MAPPER Software is applied to the aerial photo project. Seamlines or a stitching process are then assigned between each image to ensure a more seamless mosaic. The mosaic is then tiled into tiff images. Quality Control Aerials Express takes great care in the tone and color balance of the imagery. The ER Mapper software provides the automatic color correction of the imagery in batch mode. As a final review, Adobe Photoshop is used to correct color and image density where stitching is not able to fully disguise the match lines. The final step in this process is to color balance the entire image file to the best color, which gives the photography a completely natural look. Production Process for ADS40 LEICA DIGITAL IMAGERY Data processing of ADS40 imagery and metadata is a streamlined digital workflow process utilizing commercial softcopy photogrammetric software including Applanix POSPAC, Leica GPro, ORIMA, SOCET SET and Orthovista. The ADS40 sensor GPS/IMU position and attitude data is directly processed through three separate but continuous steps: Applanix POSPAC for data extracting, POSGPS for data orientation, and POSProc for creating a Smoothed Best Estimate of Trajectory (SBET) for each flight lift. The post-processed GPS data output is displayed onto the flight profile plot, which clearly shows the RMS values of the combined forward and reverse run separations, C/A Code and Carrier Phase. The output IMU data is also verified by a PDOP plot and its value compared to an acceptable threshold range. The processing of ADS40 images is run on Leica GPRO and ORIMA for bundle adjustment. The image is linked to the local coordinate system through the corresponding GPS/IMU SBET data with correct position and orientation. The residual of the tie-points are displayed instantly to reflect the accuracy of the processed data. After the bundle adjustment, ORIMA automatically displays the unit weight standard deviation, the RMS of tie points and the accuracy of the sensor position and orientation. The iteration process on the bundle adjustment is based on the selected parameters to ensure the data integrity and accuracy is within the project specification. The software also provides the measurement of reliability for variance and co-variance component analysis. This ensures the processed data is statistically satisfied on the application demand. The triangulation process involves automatic measurement of tie points. All operations are performed using the graphical working environment of ORIMA. For automatic tie point measurement, the Auto Point Measurement (APM) from Orima, using a very dense point measuring algorithm adapted for the ADS40, is called directly. Highest quality orientation results are obtained by a combined bundle adjustment. The Combined Adjustment Program CAP-A has been extended to handle all types of observations
