contour lines
Map elevation markers
Contour lines are lines on a map connecting points of equal elevation, showing the shape and steepness of terrain.
Closely spaced lines indicate steep slopes; widely spaced lines show gradual inclines.
The technique extends to any field where lines connect equal values: The contour lines on a weather map show areas of equal barometric pressure.
