blub civil Methods of Contouring Direct Method • In the direct method of contouring, the reduced level of various selected points on a contour line are obtained and their positions are located. The contours are then drawn by joining these points. It is a very accurate method but it is slow and tedious Direct method- In direct method contour to be plotted is actually traced on the ground. These points are plotted on ground and contours are marked through them. This method is fallowed where great accuracy is required. ... The indirect method is less tedious and speedy as compared to the direct method. You can find the contour interval in the map key, usually located underneath the scale of the map at the bottom center. There are two methods of contour surveying: Direct method. Indirect method. ... Indirect Method of Contouring Method of squares. Method of cross-section. Radial line method.
