Orthoimagery combines the image characteristics of a photograph with the geometric qualities of a map. The PAMAP 2005 natural color orthoimages were produced at 1-foot pixel resolution. Each orthoimage provides imagery for a 10,000 x 10,000 ft. block on the ground. The projected coordinate system is Pennsylvania State Plane North with a NAD83 datum. There is no image overlap been adjacent files. The orthoimage filenames were derived from the northwest corner of each ortho tile using the first four digits of the northing and easting coordinates referenced to the Pennsylvania State Plane coordinate system, followed by the State designator "PA," and the State Plane zone designator "N." This dataset consists of 10000 x 10000 ft. uncompressed natural color (24-bit) GeoTIFF files at a pixel resolution of 1 foot. The imagery was captured at a negative scale of 1:19200 for the purpose of producing orthophotos. Aerial survey of the Commonwealth of Pennsylvania. Orthophotos serve a variety of purposes, from interim maps to field references for earth science investigations and analysis. The digital orthophoto is useful as a layer of a geographic information system and as a tool for revision of digital line graphs and topographic maps. en 20050410 20050411 ground condition Complete Unknown -75.734987 -75.697597 41.576246 41.548164 2520000.000000 2530000.000000 510000.000000 520000.000000 The Originator, Publisher and Distributor exclude any and all implied warranties and make no warranty or representation with respect to the data files or accompanying documentation, including quality, performance, merchantability or fitness for a particular purpose.

All control was prepared under the supervision of licensed Professional Land Surveyors. 20050520 withheld Aerial photography utilizing airborne GPS techniques was acquired at an altitude of 9600' AMT producing a negative scale of 1" = 1600'. Aerial photography was exposed on color negative aerial film. 20050411 withheld Softcopy aerotriangulation utilizes the GPS ground control, airborne GPS data, and image coordinate measurements which are run through bundle block adjustment software computing the exterior orientation parameters for each image of the photogrammetric project. The original aerial film was scanned utilizing a Socet Set DSW700 precision photogrammetric scanner at a resolution of 12.5 microns. Using these scans the aerotriangulation process employs a rigorous mathematical model which detects measurement errors, and corrects for systematic image distorion, film shrikage, atmospheric refraction and camera lens distortions. The final bundle adjustment results are inspected to ensure that the RMSE meets the required 1 part in 10000. withheld 20050906 withheld withheld A combination of manual stereo compilation and auto-correlation techniques were used to generate a DTM/DEM to support the accurate generation of the orthophotos. withheld 20051101 withheld withheld Digital orthorectification includes a spatial and radiometric transformation of the scanned image from line/sample space into the specified ground coordinate system. The interior and exterior orientation parameters from the aerotriangulation process are used to project each pixel into the ground coordinate system, while the DEM is used to correct for relief displacement. The Color orthophotos are generated by Intergraph's Base Rectifier using a cubic convolution algorithm. Once the images are ortho-rectified, they are checked for geometric accuracy and image quality, and tone-balanced. The individual overlapping orthophotos are mosaicked together using Automatic Image Mosaicker (AIM) software into one seamless image data set. Final tiles are then extracted from the image set to the project tiling scheme. withheld 20060227 withheld withheld withheld RETTEW Associates, Inc. 20050520 CD-ROM GPS Ground Control To be utilized in the analytical aerotriangulation process.

The residuals of the final adjustment ensured compliance with NSSDA standards. The Pre Adjustment Gross Error Detection Statistical Test (Data Snooping, with a confidence level of 99.9%) have been applied to all observations included in the aerial triangulations. To detect small gross errors, during Adjustment Robust Estimators were used with the same confidence level and a power of the test of 1-beta=0.2. Systematic errors were eliminated through self calibration and through Additional Parameters. Their numerical stability, statistical significance, internal and external reliability were checked using Student-t test with the same confidence level and Variance/Co-variance analysis. Finally, the arrived variance factor C was submitted to a Chi-square test against the pre-adjustment variance factor using a confidence level 99.9%. During the scanning of the original aerial film, the image histogram for each frame is carefully examined to ensure that the image has been scanned so that the minimum and maximum brightness values are captured to eliminate any loss of detail due to saturation of dark or light areas. Evaluation of the DEM includes checking the terrain data for spikes and wells, omissions, and other anomalies that do not meet the project accuracy requirements. The horizontal and vertical accuracy has been tested by comparing the coordinates of well-defined points in the dataset with coordinates of the same points from an independent source of higher accuracy. The program ORTHOQC is able to match the original image pixels of pass/tie points, ground control points, and check points, extract the corresponding horizontal coordinates from the digital ortho and compare them with the original measured points in the field. Values of statistics such as RMSE, Max and Min Discrepancies, etc. are then derived and analyzed. All files are inspected by the Production Manager to ensure that they conform to the specified file naming conventions, all files load in their correct geographic position when loaded using the ASCII file header, all files conform to the project specifications for pixel resolution, file standard, dimensions, and compression, and all files do not contain blemishes such as visible seam lines, tone differences, data dropout or artifacts; scan swathing, or warped bridges and overpasses. All imagery is visually inspected for completeness to ensure that no gaps or image misplacement exists in the image area. Imagery is mosaicked to ensure complete coverage for map sheets. The imagery has been checked to ensure that the boundary and the content has been covered in its entirety. The horizontal accuracy standard follows the NSSDA-1998 standard. The maximum permissible RMSE for 95% of the horizontal check points for the mapping product is 5 feet or better. The DEM data meets the required vertical accuracy necessary to ensure that the horizontal accuracies of the orthophotos are met. 20060302 mailing and physical address
