Shaded relief maps are most directly in

Shaded relief maps are hill shading maps that show features on the surface, such as mountains, valleys, plateaus, and canyons. Areas that are flat or have few features are smooth on the map, whereas areas with steep slopes and mountains appear more rough. Colors are used to show variations in elevation. These shaded relief maps are used in the GIS software and geovisualization and are helpful in wildland fire fighting, forestry and archaeology.
