In modern mapping, a topographic map is a type of map characterized by large-scale detail and quantitative representation of relief, usually now using contour lines, but historically using a variety of methods.Traditional definitions require a topographic map to show both natural and man-made features. topographic map is typically published as a map series, made up of two or more map sheets that combine to form the whole map. A contour line is a line connecting places of equal elevation.
Mountain passes make use of a gap, saddle or col (also sometimes a notch, the low point in a ridge). A topographic saddle is analogous to the mathematical concept of a saddle surface, with a saddle point marking the highest point between two valleys and the lowest point along a ridge.
