elevation maps
Height-showing charts
Elevation maps display the height of terrain above a reference point, typically sea level.
They use contour lines, color gradients, or shading to represent changes in altitude across a landscape.
Hikers, pilots, and urban planners rely on them to understand topography: The elevation map showed a steep climb ahead.
Digital versions often render terrain in three dimensions.
