topographical map
Elevation-showing chart
A topographical map represents terrain features through contour lines showing elevation changes, along with natural features like rivers and forests and human-made structures like roads and buildings.
Hikers, engineers, and military planners use them to understand landscape: The topographical map showed a steep ravine between us and the summit.
