PASDA is pleased to have as one of its data partners the Pennsylvania Department of Conservation and Natural Resources PAMAP Program. This exceptional program has provided terabytes of valuable data to the Commonwealth of Pennsylvania including aerial photography and LIDAR data. The high resolution aerial photography from the PAMAP Program is some of the most heavily used data available through PASDA and has been accessed by a diverse range of users. From watershed organizations and local governments to the energy industry and agricultural stakeholders, PAMAP data has become an indispensable component of the data infrastructure for the Commonwealth. The PAMAP LiDAR project is one of the first in the nation to provide high-resolution elevation data for an entire state. This project started in 2006 and the final data will be collected in 2008 and completed in early 2009. This data consists of LiDAR point clouds at a 1.4 meter post spacing in LAS format, a 1-meter raster DEM, breaklines, and 2-foot interval contours. The PAMAP imagery and elevation data are provided as tiled data. The PAMAP Program has established a 10,000x10,000 tile structure covering the state, divided into North and South State Plane Zones. The North Zone tile index has 6,679 tiles, and the South Zone tile index has 6,736 tiles. To ease finding data, the Program and PASDA provide the following resources:

PASDA would like to thank the PAMAP program for providing this data to the clearinghouse and making it available for use by the citizens, non-profit organizations, government agencies, and businesses in the Commonwealth. To learn more about the PAMAP program, please visit their website.
