Contour Interval - The difference in elevation of two adjacent contour lines. Typical contour intervals are 1', 2', 5' and 10'.
Contour Interval
Difference of elevation between two consecutive contours. In general, one contour interval is used per data set.

A contour interval between intermediate contour lines to increase the topographic expression of an area, usually in areas of extremely low relief (also known as supplementary contour) e.g. 10 m contour interval and 5 m auxiliary contour interval ...
7. Contour interval: this is to be shown in the lower margin near the graphic scales. It should be in the form: "Contour interval ... metres (or feet)". When necessary the note "Supplementary contours at ... metres (or feet)" is to be added.
Set the contour interval to 10 m.
Place the output as a shapefile called Contour_10m.
After a few moments, the process will finish, and a new line layer will be added to the data frame.
Zoom in so that you can see the contour lines clearly.
Regardless of the contour interval chosen, you will notice that there are at least two types of contour lines on a topographic map. Thick contour lines, called index contours, have elevations printed on them periodically over their length.

In cartography, a contour interval is any space between contour lines, representing a difference in elevation between the lines. When calculated as a ratio against the map scale, a sense of the hilliness of the terrain can be derived.
The contour interval on this map is 3 meters (we can tell this by exaning the laebeled contours and their logical order, assuming that the shoreline is 0 meters. 'newcontour.jpg', 'docs', 800, 640, true);return false"

The standard deviation is added to the mean to identify the breakpoint for the upper contour interval and subtracted to set the lower interval.
may come as a surprise to most who've never worked on or utilized topographic data sets or maps to learn that much of the global land surface (as well as parts of ocean floors) has not been mapped at other than coarse (large value) contour intervals.
The difference in elevation between contour lines is known as the contour interval. Specific points of known elevation, called spot heights, are often included to provide more accurate information.
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.
Firstly, please note that for the scale bar for hypsometric tints the contour interval is not even - the contour intervals being 200, 300 then 500 metres for the land and 200, 1800 then 2000 for the sea.

The contour interval of the dew point contours is five degrees Fahrenheit. From the map above you can sometimes find warm fronts, cold fronts, and drylines. Fronts are usually located where the dew point changes drastically over a short distance.
The first map is from the extensive collection of 1:100,000 (20m contour interval) Ukrainian maps. The second is taken from a 1:50,000 (10m interval) Russian map of the Negev region in Is real.
2. No more than 10% of the elevations (on an elevation map) tested will be in error by more than one half the contour interval.
3. Accuracy should be tested in comparison to actual survey data.
Using the 3D Analyst toolbar, you can select the "Surface Analysis" tab and render a hillshade, slope, aspect or contour model. (Be careful not use too small a contour interval- it'll lock up the program.) ...
Many contour lines can be labeled at once by drawing a line across them, then specifying start and the contour interval. Good polygon recognition. Little work needed on vectors brought into ARC/INFO.
