A relief map is a map that depicts the variations in elevation using colors, shading, or physical modeling. Unlike a contour map, which uses lines, a relief map provides a more visual representation of the terrain. Think of it as a three-dimensional model of the land shrunk down onto a map. Mountains appear raised, valleys appear sunken, and colors often indicate different elevations. It's a great way to quickly grasp the overall shape and topography of an area.
