Using the sketch above calculate the total error in the angle and both distances. The instrument is a $2^{\text{'}\text{'}}$ total station with a $+-3mm+1\mathrm{.}5ppm$ EDM. Use centering errors appropriate to your skills.

Create a table of errors for a $1^{\text{'}\text{'}}$ total station using ${}_{PE}=(\frac{{}_p}{\sqrt[\phantom{2}]{n}})$ for $2$ through $12$ pointings $($even only$).$

Explain the difference between an EDM constant error and an EDM scale $($ppm$)$ error, demonstrate how each is independently applied to a measured distance.

What environmental systematic errors affect EDM measurements?

To conform to a $1$:$10,000$ standard what is the shortest distance you can measure with a $+-2mm+2\mathrm{.}5$ ppm EDM?
