WebJul 2, 2024 · One frequently-used type of map is called the topographical (or, topo) map. The most important feature of a topo map is that it shows the elevation (or height) of the land using contour lines (see Figure 2). Contour lines connect points around a given area (think of a mountain) that are at the same elevation. WebJan 12, 2024 · The U.S. Geological Survey (USGS) produced the first topographical survey maps that included contour representation of terrain relief, and this paved the way to soft copy, digital modeling and representation of land topography, and diminished the need for contour lines. The use of breaklines evolved as the digital mapping industry matured.
