# Survey on Latitude and Departure

PROBLEMS Asterisks (*) indicate problems that have answers given in Appendix G.

12.1* Compute the area enclosed within polygon ABDFGA of Figure 12.1 using triangles.

12.2 Similar to Problem 12.1, except for polygon BGFDB of Figure 12.1.

12.3 Compute the area enclosed by AGBA and the shoreline of Figure 12.1 using the offset method.

12.4 By rule of thumb, what is the estimated uncertainty in 870,684 ft? if the estimated error in the coordinates was +0.2 ft?

CHAPTER 10 These two do with Excel HW1

For the following traverse data:

• Calculate the departures and latitudes
• Calculate departure and latitude misclosures
• Calculate relative precision and relative precision
• Calculate the adjusted departures and latitudes
