![]() The contour lines above would make the topographic map shown here. Imagine that someone has painted lines on the mountains, and that each line is 500 feet higher than the line before. The elevation at the first hachured contour line is the same as the adjacent, lower regular contour line.Ī topographic map shows the height or elevation of land areas.Hachures on contour lines indicate the elevation is decreasing.Contour lines form V’s when they crossstreams.Contour lines NEVER cross or join contour lines of different elevations.Counter lines that are close together represent steepslopes those that are far apart represent gentleslopes.A contour line connects the points of equal elevation.The second example in Figure 2, then, shows an area that has an elevation at its center of 35 meters. In Figure 2, these lines indicate that the elevation is decreasing, notincreasing. Sometimes the contour lines have smallerlines extending inward.So the elevation of the peak of this mountain is 0ver 65 meters. In this case, there are 3more contour lines inside the 50 meter line.The intervals between each contour line on the contour map in Figure 1 are 5 meters.So each line represents an elevation of 5 meters above the line just outside of it.Notice that the first curved line has a number 50, which in this case means an elevation of 50meters. In Figure 1 a mountain is drawn as it might appear on a topographic map. And each contour line passes throughareas of equal elevation.A mountain, for example, on a topographic map is drawn as a series of curved loops, one loop inside the other.People use different kinds of maps to find out different kinds of information.A topographic map is a flat map that can be used to show elevation.
