Raw Data
Located on this DVD is a folder named LIDAR.
Each subfolder within the LIDAR
folder contains an edited Lidar
DEM GeoTIFF,
hillshade grid, contour shapefile, and tile extent shapefile for a
specific map tile.
The sub-folders are named according to the UTM coordinates of their
upper-left
corner (in thousands). Each GIS layer has an
accompanying XML file
that holds the metadata.
There is also a folder named Shapefiles
that contains the vector data that was used while creating the PDF maps. These layers
include the coastlines of Virginia and Maryland, the boundary of
Assateague Island, the boundary of Assateague Island National Seashore,
and the Lidar tile
centroids.
All files are consistent with the UTM Zone 18 N
Coordinate System, NAD83
Datum, and GRS80
Spheroid.
From the list below, select a tile to
see a folder of associated GIS layers for that
region.
