The DLG map is a digital line graph which is formed by the USGS. These types of maps come in three different types of scales including large scale, intermediate scale, and small scale maps. The DLG map has nine different categories including public land survey system, boundaries, transportation, hydrography, non-vegetative features, survey control and markers, man-made features, and vegetative surface cover. This map is represents many of the different features I have just discussed.
