Digital Line Graph (DLG)


A digital line graph (DLG) is a graph that digitally altered in order to show geographic structures more clearly, such as roads, lakes and mountains. The above map was taken of the Lake Tahoe Basin. The red outline is of surrounding roads. You can also see the outline the lake and lines that indicate where streams are going into the lake. DLGs help us to know where geographical features are located.
