The individual and merged Lidar tiles are located on this CD within the LIDAR folder. A series of subfolders house the edited Lidar DEM GeoTIFF, hillshade grid, contour shapefile, and tile extent shapefile for a specific map tile. These subfolders are named according to the UTM coordinates of their upper-left corner (in thousands of meters). Each GIS layer has an accompanying XML file that holds the metadata.

Located on the root of this CD is a separate folder named Shapefiles. This contains all the vector data that was used while creating the PDF maps. These layers include the state of Maryland coastline, boundary of Thomas Stone National Historic Site, and Lidar tile centroids.

All files are consistent with the UTM Zone 18 N Coordinate System, NAD83 Datum, and GRS80 Spheroid.
