This dataset consists of classified LiDAR (Light Detection and Ranging) elevation points produced by the PAMAP Program.
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. LiDAR 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. These data were used in conjunction with color aerial photography to create color digital orthophotos, raster digital elevation models, and topographic contours (2 ft interval).

Users should be aware that temporal changes may have occurred since this data set was collected
and some parts of this data may no longer represent actual surface conditions. Users should not use
this data for critical applications without a full awareness of its limitations. These data
depict the heights at the time of the survey and are only accurate for that time.

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.
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.
Independent accuracy testing was performed by Dewberry using 24 high accuracy
quality control checkpoints distributed on near level open bare terrain,
high grass, brush, forest and urban terrain. Dewberry uses testing procedures
consistent with those specified by both the NSSDA/FEMA and NDEP/ASPRS methods.
NSSDA/FEMA: (1) Compared to criteria RMSEz less than or equal to 0.61 ft in Open
Terrain, tested 0.535 ft; (2) Compared to criteria Accuracyz less than or equal
to 1.19 ft at 95% confidence level, tested 1.049 ft.
NDEP/ASPRS: (1) Compared to criteria Fundamental Vertical Accuracy less than or
equal to 1.19 ft at 95% confidence level, tested 1.049 ft; (2) Compared to
criteria Consolidated Vertical Accuracy less than or equal to 2.38 ft at 95%
confidence level, tested 1.134 ft.

The 95% confidence level could be phrased as "95% of the points meet or exceed
the specified accuracy level." This statistic provides information on the quality
of the data collection parameters (global quality). It can be calculated using
RMSE x 1.96 if the errors have a normal distribution, which most bare-earth points follow
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.
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.

GPS control points are used to support the acquisition of the imagery and LiDAR data. A number of "blind-point" panels were established and used during the QA/QC check of the orthophotos, LiDAR data and contour information.

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. In some areas, laser pulse rate/power were modified in order to achieve specified point spacing. As a result, these areas do not have more than 2 returns per pulse. 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.

The NOAA Office for Coastal Management received topographic files in zipped LAS files. The files contained lidar elevation and intensity measurements. The data were received in 24 blocks, 12 each for northern and southern blocks. The LAS files were in Pennsylvania North State Plane coordinates, zone 3701, NAD83 orthographic coordinates. The vertical units of the data were feet. OCM performed the following processing for data storage and Digital Coast provisioning purposes:
1. The topographic las files were cleaned of bad elevations above 3300 and below 200 ft.
2. The classifications were reclassed to properly fit the Digital Coast classifications. Class 1 - unclassified, Class 2 - ground, Class 3 - low veg, Class 4 - med veg, Class 5 - high veg, Class 6 - building, Class 7 - low point (noise), Class 8 - Model Key-point (mass point), Class 9 - Water, Class 10 - merged original classes 15/16 (road edges)
3. The topographic las files were converted from orthometric (NAVD88) heights to ellipsoidal heights using Geoid03.
4. The topographic las files were converted from a Projected Coordinate System (PA SP North) to a Geographic Coordinate system (NAD83).
5. The topographic las files' vertical units were converted from feet to meters.
6. The topographic las files' horizontal units were converted from feet to decimal degrees.
