Definition Of Contour Interval
Definition Of Contour Interval. A contour interval is a vertical distance or a difference in elevation between contour lines in a topographic map, index contour lines are bold or thick lines that appear on every fifth contour line and if the number associated with specific contour lines is increasing, the elevation of the area is also increasing. You can find the contour interval in the map key, usually located underneath the scale of the map at the bottom center.
Contour interval is the vertical distance between any two consecutive contours as shown in the figure above. If the numbers associated with specific contour lines are increasing, the elevation of the terrain is also increasing. The contour interval is kept constant for the contour plan.
The Contour Interval Is Kept Constant For The Contour Plan.
Index contours are bold or thicker lines that appear at every fifth contour line. Contour interval is the vertical distance between any two consecutive contours as shown in the figure above. Suppose a map having contour lines of 100 m, 97 m, 94 m, and so on.
Usually There Are Different Contour Intervals For The Different Maps.
Consideration in making the choice of the proper contour interval. Contour interval definition, the difference in elevation represented by each contour line on a topographic map. A contour interval is the vertical distance or difference in elevation between contour lines.
The Following Factors Govern The Selection Of Contour Interval For A Project:
You can find the contour interval in the map key, usually located underneath the scale of the map at the bottom center. The contour interval is 50 feet according to the map key. Use contour plots to display the relationship between two independent variables and a dependent variable.
To Be Precise, If Z ( T) Is The Parametrization Of The Arc, Then Having Z ′ ( T) ≠ 0 Anywhere In The Interval Of T Means Smooth.
Increasing order of contour interval represents a hilly terrain surface and decreasing order of contour interval represent a valley or ridge. The distance between two consecutive contours on a map. A contour interval is a vertical distance or difference in elevation between contour lines.
There It Is Defined That Contour Is A Piecewise Smooth Arc, Where Smooth Arc Is A Differentiable Arc Having Nonzero Derivative Of The Arc Parametrization.
The small contour interval, the survey work and plotting have to be more accurate. One use for contour integrals is the evaluation of integrals along the real line that are not readily found by using only real variable. The difference in elevation between two adjacent contour lines.
