Title: 2006-2008 PAMAP LiDAR Data of Pennsylvania (Northern Counties)
Short Name: pa2006_2008_pamap_north_m2573_metadata
Status: Completed
Publication Date: 2013-09-27
Abstract:

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).

The following are the collection dates for each county chronologically from 2006-2008:

Purpose:

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).

Data Quality

Accuracy:

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.

Horizontal Positional Accuracy:

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.

Vertical Positional Accuracy:

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.

; Quantitative Value: 0.21 meters, Test that produced the value:

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

Completeness Report:

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.

Conceptual Consistency:

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.

Process Step 2

CC ID: 1134687
Description:

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.

Process Step 5

CC ID: 1134690
Description:

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.
