What Are Contour Lines On Topographic Maps Gis Geography Cross contours may be horizontal or vertical, as on the right side of the example, or both. often, in more complex forms, cross contours will be drawn at varying angles. in this rather lumpy example, the grid of cross contours looks a bit like the gridlines on a globe or a diagram of a black hole in space. liveabout is part of the dotdash. Contour lines are simply "outlines". we typically use contour lines to define the edges of objects and details within them. contour lines are visible lines or lines defined by contrast. in other words, we can actually see contour lines in most circumstances. cross contour lines are implied lines that may or may not be visible on the subject. Here are just a few details a topographic map may bring to light: elevation changes, which are shown through contour lines. streams, rivers, lakes, and various other important bodies of water. mountains, forests, tree cover, and other large natural features. trails, roads, railroads, and other major transportation infrastructure. Contour lines show stream direction with the v shaped lines through which you see the streams and rivers run through on a topo map. because water flows downhill, the v shape always points in the opposite direction that the water is flowing. this is called the “rule of v’s”. contour lines vs. relief.

When the terrain is an overhang or cliff, contour lines will cross or touch. the cliffs in látrabjarg, iceland are up to 440 meters tall. when you generate 100 meter contours, they are very close to converging. in 3d, you can see how steep these cliffs are. so if these contours did cross, it’s very likely an overhang. Contour lines are important tools for understanding the terrain and planning routes, whether you’re a hiker, a mountaineer, or a geologist. 1. understanding elevation. one of the primary functions of contour lines is to represent changes in elevation. each contour line on a map represents a specific elevation above sea level, and the lines.
