A contour interval is the vertical distance between two adjacent contour lines. It also represents the spacing between two horizontal planes on a topographic surface. On a topographic map, contour intervals are made equal and are inversely proportional to the map scale — the larger the map scale, the smaller the contour interval, and vice versa.
