The objective is to use a total station to survey a quadrilateral with high precision, and calculate the coordinates of the corners of the quadrilateral relative to one corner and edge of the quadrilateral. For this exercise you are to be in groups of three or four. The objective is to measure all angles and distances in the quadrilateral we used in the GPS exercise. See the handout on Surveying a quadrilateral .
Tripods are to be set up over all four points.
Reflectors will be on three points, and the instrument on the fourth. The angles between the three reflectors are then to be measured, as well as the distance between the instrument and the reflectors. All angles should be doubled, and you should repeat and average your angle measurements for accuracy. Each person is responsible for running the instrument at least one point. On the days indicated the group has priority on the equipment needed to measure the quadrilateral.
