A contour map is a type of map that represents the three-dimensional shape of the Earth’s surface in a two-dimensional format. Contour maps are used to show the elevation of the land at various points on the map by using contour lines, which are lines that connect points of equal elevation.

Each contour line on a contour map represents a specific elevation, and the spacing of the lines indicates the steepness of the slope. Contour lines that are close together represent a steep slope, while contour lines that are far apart represent a gentle slope.

Contour maps are commonly used in a variety of fields, including geography, geology, and civil engineering. They are used to analyze the topography of an area, plan infrastructure and development projects, and assess the impact of natural disasters such as floods and landslides.
