Description: This dataset, produced by the PAMAP Program, consists of a raster digital elevation model with a horizontal ground resolution of 3.2 feet. The model was constructed from PAMAP LiDAR (Light Detection and Ranging) elevation points. 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 seamless DEM Raster Dataset was created using the following scripting procedure:First, the script must delete the file geodatabase, PA_DEMs, containing the seamless DEM raster dataset if it has been created previously. This is because the geodatabase cannot be overwritten. The next step recreates the geodatabase.The script then creates a file geodatabase, PA_DEMs, which will contain the seamless raster dataset for the MAWC area of service. A new raster dataset, DEMs_all, is then created by the script within the PA_DEMs file geodatabase. This raster dataset will contain a seamless mosaic of all DEMs within the MAWC area of service. The script then loops through each subfolder in the main folder containing the DEM TIFF files, then using the “mosaic” function, adds each DEM file to the DEMs_all raster dataset. After all DEM files are added, the seamless raster dataset is complete.
