Hallo,
Is it possible to level loop check (closing polygone composed of leveling lines) in JAG3D for 1D network ?

Hello,

Is it possible to level loop check (closing polygone composed of leveling lines) in JAG3D for 1D network ?

Just sum up the height differences to get the error of the loop. It is a simple task not implemented in JAG3D. However, you can evaluate the loop error by cutting the loop. Let the loop be A-B-C-A. To evaluate the error, change the loop to A-B-C-D and compare the coordinates of A and D.

Kind regards
Micha

For large network, it means when this option exists. Anyway JAG3D program is great.

Hello,

JAG3D does not analyse the topology of your network. There is no loop, line, traverse etc. There are only observations between two points to be analysed. Moreover, most (digital) leveling instruments analyse the loop error during the fieldwork. Maybe, you can use such function.

Anyway JAG3D program is great.

Thank you!

Kind regards
Micha
