How do you draw a contour line on a grid?
A general way to draw contour lines is to determine the values of f(x,y) at regular intervals of x and y, creating a grid of values. The location of a contour line can then be approximated by drawing it at or between the appropriate grid values.
What does contour line mean in art?
A contour line defines the outline of a form, as well as interior structure, without the use of shading. A fundamental basis of drawing, contour lines are usually the first technique children adopt to draw people, houses, and trees.
What does contour mean?

What is the space between contour lines called?
The space between the contour lines is called the contour interval and represents a specific (set) distance. If the contour interval is 50 feet, the vertical space between the two contour lines is 50 feet.

How do you calculate contour lines?
Divide the difference in elevation between the index lines by the number of contour lines from one index line to the next. In the example above, the distance 200 is divided by the number of lines, 5. The contour interval is equal to 200 / 5 = 40, or 40-unit contour intervals.
What is the contour interval given in the grid sheet?
A contour line is a line drawn on a topographic map to indicate ground elevation or depression. A contour interval is the vertical distance or difference in elevation between contour lines.
