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.

A road that contours a mountain follows along its edge and a mattress that contours to your body, adjusts to your shape.

What are the 5 Rules of contour lines?

Rule 1 – every point of a contour line has the same elevation. Rule 2 – contour lines separate uphill from downhill. Rule 3 – contour lines do not touch or cross each other except at a cliff. Rule 4 – every 5th contour line is darker in color.

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.
