contour interval

The contour interval should be the same over a single map.

Maps measure 17 x 11 inches; contour interval 20 feet.

The scale is 1:500,000, with a contour interval of 500 feet.

An area of low slope generally uses contour intervals of 10 feet or less.

The contour interval is a maximum of 20 metres.

Usually contour intervals are consistent throughout a map, but there are exceptions.

The contour interval varies greatly and is based on the maximum recorded value over the network for each event.

The contour interval is 2 ft between successive contour lines.

Contour intervals, spot elevations, and horizontal distances are also specified in meters.

With this system it is possible to draw a set of regularly spaced lines which the computer interprets as contour intervals.

The contour interval is about 0.3μm since a He-Ne laser was used in the system.

Land forms are shown using contour lines with a contour interval of 5 metres.

Relief shown by 25 meter contour intervals.

In cartography, the contour interval is the elevation difference between adjacent contour lines.

Sometimes intermediate contours are present in flatter areas; these can be dashed or dotted lines at half the noted contour interval.

On topographic maps, stream gradient can be easily approximated if the scale of the map and the contour intervals are known.

Like a topographic map, each band of color represents a contour interval; in this case, the intervals represent 2.8cm of movement.

The contour interval of a contour map is the difference in elevation between successive contour lines.

The relief is represented by means of contours or isolines (to show areas at the same relative elevation), and color-coded contour intervals.

Other information is required to be on the printed map although the presentation is not specified, e.g. scale, contour interval and scale bar.

The elevation of the highest summit in the county appears to be between 1730' +/- 10' due to the 20' closed contour interval according to this map:[1].

Of course, to determine differences in elevation between two points, the contour interval, or distance in altitude between two adjacent contour lines, must be known, and this is given at the bottom of the map.

The contour intervals are 0.04g for PGA and the three spectral acceleration parameters (only two of which are used by HAZUS), and 4 inches/second for PGV.

By counting the number of lines that cross a certain segment of a stream, multiplying this by the contour interval, and dividing that quantity by the length of the stream segment you can determine the stream gradient.

In addition, because a computer-produced map can be redrawn quickly (or viewed on a graphics terminal) the cartographer can experiment with different contour intervals, or levels of shading, and can try different perspectives and projections with ease.
