The PAMAP contours are jagged compared to the contours from the printed quadrangle map, a reflection of the data-centric (as opposed to cartographic) origin of the PAMAP contours. Obtaining the Data. As mentioned above, the official distributor of PAMAP lidar data is PASDA. Lidar data can be attributed with RGB (red, green, and blue) bands. This attribution often comes from imagery collected at the same time as the lidar survey. GPS time. The GPS time stamp at which the laser point was emitted from the aircraft. The time is in GPS seconds of the week. Scan angle. The scan angle is a value in degrees between PAMAP. PAMAP involved the collection of high-resolution digital aerial photographs and lidar elevation data that can be used to produce high-quality digital base maps for Pennsylvania. Orthorectified photographs and bare-earth digital elevation models (DEMs) processed from the lidar data become the base layers in digital maps.
