An orthoimage is a remotely sensed image that has been positionally corrected for camera lens distortion, vertical displacement, and variations in aircraft altitude and orientation. Orthoimagery combines the image characteristics of a photograph with the geometric qualities of a map. Source images were captured in natural color at a negative scale of 1:19200. PAMAP data are organized into blocks, which do not have gaps or overlaps, that represent 10,000 feet by 10,000 feet on the ground. The coordinate system for blocks in the northern half of the state is Pennsylvania State Plane North (datum:NAD83, units: feet); blocks in the southern half of the state are in Pennsylvania State Plane South. A block name is formed by concatenating the first four digits of the State Plane northing and easting defining the block's northwest corner, the State identifier "PA", and the State Plane zone designator "N" or "S" (e.g. 45001210PAS). Aerial survey of the Commonwealth of Pennsylvania. Orthoimages serve a variety of purposes-- from interim maps to field references for earth science investigations and analysis. The digital orthoimage is a useful layer in a geographic information system for revision of digital line graphs and topographic maps. en ground condition Complete Unknown -75.735836 -75.698463 41.548809 41.520727 2520000.000000 2530000.000000 500000.000000 510000.000000 None digital orthophoto digital image map aerial photograph rectified photograph rectified image orthophoto DEM LiDAR DMC Digital Mapping Camera ISO 19115 Topic Category imageryBaseMapsEarthCover None Pennsylvania Lackawanna County Luzerne County Wyoming County None 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.

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%. The LiDAR flying height, field of view, laser repetition rate, aircraft speed, and the maximum baseline distances from the aerial platform to the ground based GPS stations have been fine tuned to ensure an RMSEz of the processed data at the 18.5 cm level for the bare earth surface as required by the FEMA guidelines. See the PAMAP Technical Proposal dated November 30, 2007 for further QA/QC procedures. 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, 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 and contours are met.

The aerotriangulation process employs a rigorous mathematical model which detects measurement errors, and corrects for systematic image distortion, 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 withheld 20080630 withheld Sandra Elfreth-Howery BAE Systems Project Manager mailing and physical address

Raw LiDAR data was collected using a sensor equipped with an airborne GPS/IMU system. Flight lines with a 30% sidelap were flown with a nominal average LiDAR point spacing of 1.4 meters using a 43 degree field of view (full angle) at a laser pulse rate of 40.6 kHz. The raw LiDAR data is processed and filtered to remove LiDAR points on elevated features such as vegetation, buildings, cars, etc. in order to create a bare earth surface meeting the accuracies required for orthophoto and contour generation. withheld withheld 20080630 withheld Sandra Elfreth-Howery BAE Systems Project Manager mailing and physical address

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. 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 and the final tiles are then extracted from the image set to the project tiling scheme. withheld withheld withheld 20090515 withheld Sandra Elfreth-Howery BAE Systems Project Manager mailing and physical address
