Radiation is a surveying technique used to determine the distance from an instrument station to a point by measuring the angle between the line of sight to the point and a known reference line.
Intersection is a surveying technique used to determine the location of a point by measuring the angles between the lines of sight to the point from two known stations.
Traversing is a surveying technique used to determine the location of a series of points by measuring the angles and distances between the points.
