the detailed mapping of the configuration and relief features of a region
On a topographic map, contour lines that are closer together indicate a steeper slope.
The average slope is the ratio of the change between two points
A topographic map shows the physical features of the land, such as elevation, contour lines, and natural landmarks like mountains and rivers. In contrast, a road map primarily focuses on highways, roads, and transportation routes, providing information for navigation and getting from one place to another.
A topographic map shows equal lines of elevation, in set distances which can vary between maps (dependent on the grade of elevation change). elevation,relief,and slope.
Contour lines that are close together on a topographic map indicate an area of steep slope. If they essentially overlap you have a cliff.
contour lines
contour lines that are very close together
elevation. the closer the lines the steeper the slope.
Hill,Slope or Mountain
If the contour lines are far apart, then that indicates the land has a gentle slope (low slope).
If the topographic lines are closer together it means that it has a steeper slope grade, if they are farther apart, it means that they have a more relaxed slope grade. There is usually a scale on the map that can tell you in exact measurements of the slope.
