Additional information is available at the PAMAP website: www.dcnr.state.pa.us/topogeo/pamap. 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: Chester : 20060321 - 20060502 ---- Cumberland : 20060406 - 20060429 ---- Dauphin : 20060406 - 20060429 & 20060321 - 20060502 ---- Delaware : 20060406 - 20060429 ---- Fayette : 20060406 - 20060429 & 20070430 ---- Franklin : 20060406 - 20060429 & 20060321 - 20060502 ---- Fulton : 20060406 - 20060429 ---- Greene : 20060406 - 20060429 ---- Huntingdon : 20060406 - 20060429 ---- Indiana : 20060406 - 20060429 ---- Juniata : 20060426 - 20060430 ---- Lancaster : 20060426 - 20060430 ---- Lawrence : 20060426 - 20060430 & 20060406 - 20060429 & 20060321 - 20060502 ---- Adams : 20070430 ---- Allegheny : 20070430 ---- Armstrong : 20070430 ---- Beaver : 20070430 ---- Bedford : 20070430 ---- Berks : 20070430 ---- Blair : 20070430 ---- Bucks : 20070430 ---- Butler : 20070430 ---- Cambria : 20070430 ---- Lebanon : 20080330 - 20080418 & 20080419 - 20080420 ---- Lehigh : 20080330 - 20080418 & 20080419 - 20080420 & 20080415 - 20080419 & 20080423 - 20080424 ---- Mifflin : 20080410 - 20080411 & 20080330 - 20080418 & 20080410 - 20080419 ---- Montgomery : 20080410 - 20080411 & 20080425 ---- Northampton : 20080410 - 20080418 & 20080402 - 20080403 & 20080321 - 20080326 ---- Perry : 20080410 - 20080419 & 20080410 - 20080418 & 20080424 & 20080415 - 20080419 ---- Philadelphia : 20080410 - 20080419 & 20080424 & 20080414 - 20080510 ---- Schuylkill : 20080414 - 20080425 & 20080414 - 20080510 & 20080321 - 20080326 ---- Snyder : 20080414 - 20080425 & 20080410 - 20080418 - 20080510 ---- Somerset : 20080414 - 20080425 & 20080410 - 20080418 & 20080321 - 20080326 ---- Washington : 20080419 - 20080420 & 20080415 - 20080419 & 20080423 - 20080424 & 20080402 - 20080403 ---- Westmoreland : 20080419 - 20080420 & 20080423 - 20080424 ---- York : 20080419 - 20080420 ---- This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data. 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). credit: PAMAP Program, Bureau of Topographic and Geologic Survey, PA Department of Conservation and Natural Resources The custom download may be cited as National Oceanic and Atmospheric Administration (NOAA) Digital Coast Data Access Viewer.

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. dateTime: DateTime: 2007-03-08T00:00:00 processStep: (LI_ProcessStep) description: Horizontal and Vertical control points were acquired utilizing GPS collection techniques.

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. dateTime: DateTime: 2013-09-25T00:00:00 source: (LI_Source) description: Source Contribution: GPS control points are used to support the acquisition of the imagery and LiDAR data.
