PAMAP is a new, electronic map of Pennsylvania being compiled by the PA Department of Conservation & Natural Resources (DCNR). As part of this program DCNR has collected high-resolution aerial photos and extremely accurate elevation data for the entire state. The elevation data was collected using LiDAR (Light Detection and Ranging) technology and processed into 2' contours. Some of this data is currently available to the public. A total of 67 counties have been flown, processed, and checked for quality. Individual downloads of these files in ESRI Shapefile format can be accomplished at the Pennsylvania Spatial Data Access (PASDA) web site for free. OSGIS has developed several services and products to help more organizations use the PAMAP LiDAR data, including the LiDAR derived contours in AutoCAD DWG format.
