What are topographic maps?

Topographic maps contain data on the natural features of the land, such as elevations, contours, water bodies, and other features, plus they may also contain man-made features such as roads, railroads, buildings and structures, etc. The main concept of topographic maps is that they show the way the landscape would appear if viewed from above. A detailed history of the USGS topographic map program describes the creation of this valuable series. For more on the USGS topographic maps, see:
