Older survey

Retracing a survey from 1981. Back then it was T2 and topcon DM on top.?ÿ

For us it's deep timber, Ponderosa pines and brush.?ÿ

Today it's GPS R10 and Robot, so traversing through the trees needs to be closed somehow.?ÿ

So we're thinking bout going back up next time to close everything out and then look at the surveys.?ÿ

At first I thought I was hooking the end of the line to calc points, they were 249.41'(r), 249.42'(m), 435.57(R), 435.57'(m), 251.54(r), 251.52"(m), 435.6'(r), 435.63'(m).

Guess we don't need to close any traverse out.?ÿ

The bearings are constantly 15' rotated so that checks also.?ÿ

Back then we were often on SPC but this was an astronomic survey today it's on SPC, and the 15' is very close to the correct rotation.?ÿ
