Students were divided into groups to accomplish their tasks. They plotted the area of site selected for survey through radiation method on drawing sheet at the field and also studied the intersection method. Intersection method is useful where it is not possible to measure the distances on ground as in case of a mountainous area. Hence, this method is employed for locating inaccessible points, the broken boundaries, rivers, fixing survey stations, etc. They also took the level reading at different edge points of the site and calculated the area of site which was done by plane table surveying.
