PAMAP Program, PA Department of Conservation and Natural Resources, Bureau of Topographic and Geologic Survey 20100705 PAMAP Program Topographic Contours (2 ft Interval) of Pennsylvania Middletown, PA PAMAP Program, PA Department of Conservation and Natural Resources, Bureau of Topographic and Geologic Survey 18002610PAS_cont vector digital data This dataset, produced by the PAMAP Program, consists of topographic contours mapped at an interval of 2 feet. 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 20080313 20080317 ground condition Complete Unknown -75.467471 -75.430972 39.804680 39.776523 2610000.000000 2620000.000000 170000.000000 180000.000000 -4.000000 114.000000 None DEM contours topography LiDAR DMC Digital Mapping Camera ISO 19115 Topic Category imageryBaseMapsEarthCover elevation None Pennsylvania Delaware 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, 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).

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 Debra A.

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 Debra A.
