Contours were derived from a bare-earth digital elevation model constructed from PAMAP LiDAR (Light Detection and Ranging) elevation points. 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). General-purpose aerial topographic survey of the Commonwealth of Pennsylvania. Topographic data are useful for a variety of scientific and resource management applications such as hydrologic modeling, resource monitoring, mapping, global change research, and landscape visualization. en 20070421 20070423 ground condition Complete Unknown 2070000.000000 2080000.000000 510000.000000 520000.000000 696.000000 1982.000000 None DEM contours topography LiDAR DMC Digital Mapping Camera ISO 19115 Topic Category imageryBaseMapsEarthCover elevation None Pennsylvania Cumberland County Franklin County Huntingdon County Juniata County Mifflin County Perry 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 January 11, 2006 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, all files conform to the project specifications for file standard and content. All files are visually inspected for completeness to ensure that no gaps or misplacement exists in the data. The files have 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 vertical accuracy will meet the requirements of NSSDA at the 95% confidence interval (1.96 x RMSE). RETTEW Associates, Inc. 20060424 CD-ROM 20060424 ground condition GPS Ground Control GPS control points are used to support the acquisition of the imagery and LiDAR data. Photo identifiable ground control points (panels) based on the control plan are utilized in the analytical aerotriangulation process. A number of "blind-point" panels were established and used during the QA/QC check of the orthophotos, LiDAR data and contour information. All horizontal and vertical control was prepared under the supervision of licensed Professional Land Surveyors.

Horizontal and Vertical control points were acquired utilizing GPS collection techniques. All control was prepared under the supervision of licensed Professional Land Surveyors. 20060424 GPS Ground Control Digital aerial photography was obtained utilizing a Zeiss/Intergraph DMC camera in accordance with the project specifcations. The photography was obtained at an altitude of 10,000 feet AMT and captured at a pixel resolution of 1.0 foot. 20070423 Aerial Photography 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 aerotriangulation process employs a rigorous mathematical model which detects measurement errors, and corrects for systematic image distorion, 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. GPS Ground Control Aerial Photography 20070630 Analytical Aerotriangulation LiDAR collection and processing generally adhered to FEMA Guidelines and Specifications for Flood Hazard Mapping Partners, Appendix A: Guidance for Aerial Mapping & Surveying, Section A.8: Airborne Light Detection and Ranging (LiDAR) Surveys. 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. Raw LiDAR GPS Ground Control 20080624 Processed LiDAR To supplement the LiDAR data, photogrammetrically compiled breaklines are collected along various planimetric features and significant breaks in grade. The processed LiDAR data is combined and integrated with these breaklines to generate a final terrain surface of the project area. This surface was then used to support the accurate generation of the orthophotos and 2' contours. Aerial Photography Analytical Aerotriangulation Processed LiDAR 20080624 DEM The DEM was used to create contours at a two foot interval in MicroStation format. The contour types include index, index depression, intermediate, and intermediate depression contours. The contours were then exported in DXF format for conversion to ESRI 3D Shapefiles. Topology checks are performed to find errors in edgematching, dangles, and intersections. DEM 20080724 ESRI 3D Contour Shapefile Metadata imported.
