WebFeb 5, 2024 · A map with contour lines on it is called a topographic map. Topographic maps use a combination of colors, shading and contour lines to represent changes in elevation and terrain shape. Essentially, topographic maps represent the three-dimensional landscape of Earth within the two-dimensional space of a map. Credit: ThingLink Terrain or relief (also topographical relief) involves the vertical and horizontal dimensions of land surface.
