Direction - what it is? (Software)

surveyor @, Sonntag, 08. Oktober 2017, 20:17 (vor 68 Tagen) @ Micha

Thank you Micha.

I zoomed in as you suggested and
discover couple more questions :) :

1) My zoomed in sketch for the 1D2D3D (mine) network is
looking a bit different from the tutorial:

For example error ellipses seems to be much bigger, point 788 is green (not changing)
but in my version it has an arrow and pink color (changing).


Figure 1: Network sketch of the underground system

This is my zoomed in.

Zoomed in part of the mine network

Is this a valid result?
-----------------------------------

2) What is the difference between datum point,reference point and stochastic point.

-----------------------------------

3) Is there an example of the network planing (pre-analysis).

----------------------------------
4) In tutorial survey_plan point 4 seems to have invalid coordinate
file: points_new_2d.txt
....
4 1098 2043
....

it seems that better initial approximation will be

4 998 2043


Results with original coordinate

Results with "fixed" coordinate

Regards.
