Two independent papers introduced the topographic distance and defined the watershed as a SKIZ of the minima for this distance [36],[29]. The equidistant lines from the minima are the level lines of the topographic surface. This definition was thus compatible with the presentation of the watershed lines

WebMapping is a crucial part of Earth science. Topographic maps represent the locations of geographical features, such as hills and valleys. Topographic maps use contour lines to show different elevations on a map. A contour line is a type of isoline; in this case, a line of equal elevation. If you walk along a contour line you will not go uphill ...
