Stakeout Computation
Station Point: N += Sta * cos(Az), E += Sta * sin(Az)
Offset: N += Off * cos(Az+90), E += Off * sin(Az+90)
Right offset = Az+90, Left offset = Az-90
Compute stakeout point coordinates from a baseline direction, station along the baseline, and perpendicular offset.
What would make it better?
Station Point: N += Sta * cos(Az), E += Sta * sin(Az)
Offset: N += Off * cos(Az+90), E += Off * sin(Az+90)
Right offset = Az+90, Left offset = Az-90
