What is contour interval definition?

Contour interval definition refers to the vertical distance between adjacent contour lines on a topographic map. It represents the difference in elevation between each contour line and can be expressed in feet, meters, or other units of measurement. For example, a contour interval of 10 feet means that each contour line on the map represents a change of 10 feet in elevation. The contour interval is determined by the scale and elevation range of the map, and can vary from map to map. A smaller contour interval provides greater detail and accuracy in depicting the terrain features, while a larger contour interval is used for maps that cover a wider area or have a broader elevation range. The contour interval plays a crucial role in understanding the topography of an area and helps hikers, surveyors, and other users to plan their routes and navigate safely through the landscape.
