Shown above is a DLG map. DLG stands for Digital Line Graphs and are used by the USGS (United States Geological Service.) Digital line graph maps are used to view various streets, rivers, and certain boundaries. The map above is a digital line graph map of Gettysburg, Pennsylvania. It is easily understood it is a DLG because of the clear roads, streets, and boundaries that are shown throughout the map.
