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.10 sept. 2020

What are 3 types of contour lines?
1. Index lines are the thickest contour lines and are usually labeled with a number at one point along the line.
2. Intermediate lines are the thinner, more common, lines between the index lines.
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 block contouring?
By squares (block contouring)- In this method the area to be surveyed is dividing into no of the square of size 5 to 20m. depending upon the nature of ground and contour interval required. The elevation of the corner of the square is determined by the mean of the process of levelling.
How do you calculate contour survey?
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.
