The difference, in feet or meters, in elevation between two adjacent contour lines.

The contour interval on a topographic map is the amount of vertical distance between contour lines. For example, a forty-foot contour interval means that each contour line represents a change in elevation of forty feet.

Describes the elevation difference represented between successive contour lines on a topographic map.

The difference in elevation represented by two adjacent contours.

The elevation difference between adjacent contour lines

The difference in elevation of two adjacent contour lines. Typical Contour Intervals are 1', 2', 5' and 10'.

the difference in elevation, in feet or meters, between two adjacent contour lines. This figure can be found near the scale on Trails Illustrated maps.

difference in elevation between two consecutive contour lines

Difference in elevation between two adjacent contours.

The difference in elevation between adjacent contours. For example, on a map with a contour interval of 10 feet, the ground rises or drops 10 feet with each successive contour. Contour intervals can vary greatly depending on scale and terrain. On most USGS maps, the contour interval is listed in the center of the bottom margin, above the scale bar.

The difference in elevation between successive contour lines

the difference in elevation between adjacent contour lines on a map.

The vertical distance between two adjacent contour lines.

Difference in elevation between two successive contour lines. The interval at which contours are drawn on a map depends on the amount of the relief depicted and the scale of the map.

The difference in surface values between contours.

The interval at which contour lines are drawn on a map.
