Contour fail to show some of the heights due to limitation of vertical interval.
It can be used in drawing cross section of the given features on the mapped areaĭisadvantages of using contour to represent relief on the map.
In this instance, it looks the same but if I vary the function it will not.
It provide the basis for coloring method. \begingroup I am using the NDSolve Value to find the value of xtrajt, I do not want the value of NDSolve, yet here all the plots are plotting the value of NDSolve instead of xtrajt.
By reading contour interval it is easy to determine the different elevation of the landscape.
contour (X,Y,Z) specifies the x and y coordinates for the values. The column and row indices of Z are the x and y coordinates in the plane, respectively. MATLAB automatically selects the contour lines to display.
It depict slope and size of different landforms on map. contour (Z) creates a contour plot containing the isolines of matrix Z, where Z contains height values on the x - y plane.
Advantages of using contour to represent relief on the map The following are the advantages and disadvantages of using contour as the method of representing relief on the mapped area, starting with advantages.
two contours of different elevation usually do not cross each other.
when two or more contour lines merge with each other, they represent feature of vertical slope such as cliff and waterfall.
contour lines and their shapes represent the height and slope or gradient of the landforms.
a contour lines is drawn to show places of equal heights.
The horizontal distance between contour lines is large when the slope is gentle and decreases with increasing slope gradient features of contour lines While contour interval between two successive contour lines is constant, the horizontal distance (horizontal equivalent) between contour lines varies from place to place depending on the nature of the slope. The contour lines on the map provide a useful insight into the topography of an areaĮarlier ground surveys and leveling were used to draw contours on topographical maps however, nowadays aerial photographs are used insteadĭistance between one contour line and another is called contour interval and is generally expressed in meters. Contour are lines drawn in the map to show the areas with equal altitude from sea level.Ī map showing the landforms of an area by contours is called a contour map
