1 – Describe how the total station employs different wavelengths to measure a distance.

2 – What is the prism constant? Why is it important to know that value when using a new prism?

3 – Horizontal control is extended by establishing a traverse and vertical is extended by a level loop.

4 – What are the purposes, as mentioned in the lecture, of establishing a traverse?

5- Explain the difference between closed and open traverse. Comment on the advisability of using open traverses.

6- What should be the sum of the interior angles for a closed polygon traverse that has a) 6sides b) 8 sides and c) 12 sides?

7- The interior angles in a five sided closed polygon traverse were measured as A = 139°10”11”, B = 126°17’43”, C = 94°28’30”, D = 71°04’59” and E = 108°58’31”. Compute the angular misclosure. For what order and class is this survey?

8- In adjusting measured traverse angles, why aren’t adjustments made in proportion to angle sizes?

9- Compute and tabulate for the following closed-polygon traverse:

(a) bearings (b) departures and latitudes

(c) linear misclosure (d) relative precision

(e) adjust the traverse using the bowditch rule assuming the coordinates of A are 5000.00E and
