topographical maps

Elevation-showing charts

Topographical maps show the physical features of terrain—hills, valleys, rivers, forests—using contour lines to represent elevation changes.

Lines close together indicate steep slopes; lines far apart show gentle grades.

Hikers, surveyors, and military planners rely on them to understand landscape before seeing it: We studied the topographical map to find the easiest route through the mountains.
