- Abstract:
-
The VTORTHO_0_5M_PAN_2011 data includes pancromatic (black and white)
orthophotography (orthophoto) at 1:5000 scale (0.5 meter cell resolution).
The imagery was acquired in April 29, April 30, and May 1, 2011 for Rutland and Windsor Counties in Vermont.
This metadata record describes the acquisition and production of natural color and color infrared digital ground orthoimagery covering a portion of Vermont State. The digital orthophotography and color infrared digital orthos are composed of 24 bit natural color digital orthos at a scale of 1 to 5,000 with a 0.5 meter pixel resolution.

- Logical_Consistency_Report:
-
"Compliance with the accuracy standard was ensured by the placement of GPS ground control. The following checks were performed. 1. The ground control and airborne GPS data stream were validated through a fully analytical bundle aerotriangulation adjustment. The residuals of the adjustment met the required standards for accuracy which are 1 part in 10,000 of the flying height for the horizontal position (X and Y) and 1 part in 9,000 or better of the flying height in elevation (Z). 2. The DTM (Digital Terrain Model) data was checked against the project control. The technician visited and confirmed the accuracy of the project mass points during initial compilation. 3. Any topographic data was checked for edge match, consistency of attribution, and cartographic quality through visual inspection. 4. Digital orthophotography was validated through an inspection of edge matching and visual inspection for image quality."

"The aerial imagery acquisition for Vermont State was flown to support the creation of digital orthophotography with a 0.5 meter pixel resolution. The aerial photographic mission was composed of a total of 3 lifts consisting of 29 North-South oriented flight lines. Photography was obtained at an altitude of 16,047 feet above mean sea level. Aerial photography was collected in conjunction with airborne GPS; the stationary GPS receiver was positioned over a control point located at the airport. All imagery was collected using the Leica ADS40 digital pushbroom sensor."

Vermont Agency of Transportation successfully established ground control for the project area. A total of 24 ground control points were acquired using GPS for both vertical and horizontal coordinate values.

- Process_Description:
-
EarthData utilized an InfoTerra Pixel Factory workflow for processing the aerotriangulation for the orthoimagery of project area. The airborne GPS data was processed and integrated with the inertial measurement unit (IMU). The resulting imagery and control were imported into the InfoTerra Pixel Factory system for use in the aerotriangulation. The ADS40 imagery was downloaded onto the EarthData server and brought over to the UNIX based InfoTerra Pixel Factory system. The ground control was used in conjunction with the processed airborne global positioning system (ABGPS) results for the aerotriangulation. The ground control points were read in all available imagery and tie points between flight lines were selected. A fully analytical bundle adjustment was run. The properly formatted InfoTerra Pixel Factory results were used for subsequent processing. All final results were output into an AT report which is being delivered with the final orthoimagery.

"InfoTerra Pixel Factory was used in the processing of the DSM for orthorectification of the imagery covering a portion of Vermont state project area. InfoTerra Pixel Factory digital surface modeling is based on an auto correlated pixel-matching system within the InfoTerra Pixel Factory software. The auto correlated digital surface model (DSM) surface represents the initial surface model. The following is the process used. 1.The technician verified that there were no voids, and that the data covered the project limits. 2. The technician runs a macro to automatically filter out non-ground features such as trees, noise, and buildings. 3. The technician checks each tile and manually edits where necessary. 4. The technician interpolates voids left over from feature removal. 5. The resulting digital elevation model (DEM) is used in the rectification of the orthoimagery and the deliverable is provided in ASCII format for each tile."

"The digital orthophotography is comprised of a 24 bit, natural color and color infrared, 0.5 meter pixel resolution ground orthos for the project area. The InfoTerra Pixel Factory was used in the generation of the orthoimagery covering all project tiles. After the rectification process was run using the processed DEM surface, quicklook (reduced resolution rectification) ortho for all flight lines were created. The quicklook orthos were radiometrically balanced using FEDI proprietary software. The radiometrically balanced imagery were then re-imported into the Pixel Factory and the histogram from the quicklook was applied to the full resolution imagery. Quicklook orthos were also used to generate the automatic mosaic lines, which were placed to mosaic the full resolution ortho of the ADS40 imagery strips. An initial QA/QC was performed by the technician to ensure that the mosaic lines were appropriately placed and that there was appropriate imagery coverage. The final imagery data set is removed from the InfoTerra environment in a process called "packaging" where the individual tiles are created. All data processing in the InfoTerra system is performed in UTM meters; it is during "packaging" that final datum and projection are defined. The created tiles are reviewed to ensure the output was successful and ground control points are measured and verified for accuracy. QA/QC was performed on each tile looking for anomalies, smears and other indications of problems within the digital Orthophoto creation process, and interactive radiometric adjustments were applied where needed. Additional global radiometric adjustments were applied to the completed orthos in Adobe Photoshop to enhance the color and/or contrast as needed. The orthos were clipped to a project boundary consisting of 4,000 meter by 4,000 meter tile layout. The orthos were produced as GEOTIFF with a .prj file using GDAL software. A Fugro EarthData proprietary software was used to generate the specified header information in the associated TFW file. All data was delivered on firewire."
