In a traverse with a total length of 2180.91 m, one course has a latitude of 380.00 m and a departure of
0.00 m. The closure of the traverse in latitude is 0.042 m and in departure is 0.145 m. What is the
adjusted latitude and departure for that course if a compass rule adjustment is used? - ANSWERSlat adj=
= (course dist./total dist.)(lat error)

=(380.00/2180.91)(0.042)

=0.007 m



depart adj = (course dist/total dist.)(depart erro)

= (380.00/2180.91)(0.145)

=0.025 m



380.00 - 0.007 = 379.993 (adj. lat)
