Abstract:
The VTORTHO_0_5M_CLR_2011 data includes truecolor and color infrared (4 band) 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 the greyscale digital orthoimagery covering a portion of Vermont State. The digital orthophotography are composed of 8 bit greyscale digital orthos at a scale of 1 to 5,000 with a 0.5 meter pixel resolution.

Attribute_Accuracy_Report:
This data has been produced to be fully compliant with the American Society for Photogrammetry and Remote Sensing Accuracy Standards for Class 1 mapping requirements (ASPRSC1) at a scale of 1 to 5,000.
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.

Source_Contribution:
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.

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.

Process_Description:
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."

Process_Description:
The original digital orthophotography is comprised of a four band (RGB color + color IR) imagery. This imagery was converted where the Red, Green, and Blue bands were converted to an 8 bit greyscale image having a 0.5 meter pixel resolution for the project area. The orthos were clipped to a project boundary consisting of 4,000 meter by 4,000 meter tile layout. The greyscale orthos were produced in both uncompressed and compressed (JPEG2000 format using a compression factor of 18:1). All image data was delivered on firewire.
