shaded relief


Also found in: Dictionary, Wikipedia.

shaded relief

A cartographic technique that provides an apparent three-dimensional configuration of the terrain on maps and charts by the use of graded shadows that would be cast by high ground. The darker the shade, the higher the elevation of the ground. Shaded relief usually is used in combination with contours. See hypsometric tinting.
