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
which contains the vector data that was used while creating the pdf maps. These layers
include the state of Virginia coastline, Colonial National Historical
Park boundary, and 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.
