Solving Traverse

by marcellini roberto @, Friday, July 03, 2020, 08:19 (38 days ago)

Dear Sirs,
I would like to ask you, if possible, how to be able to readjust and solve with JAG3D the traverse that has been resolved through an excel sheet that you can download from this link:
https://we.tl/t-EIe6kypuAN
I'll appreciate if you can give a step by step instruction to introduce the data inside JAG3D.

Thank and Regards

Hi Roberto,

I'll appreciate if you can give a step by step instruction to introduce the data inside JAG3D.

First of all, you have to create some files containing your observations and points. The easiest file format is a simple flat file having some white-spaces (i.e. blanks or tabs) as column-separator.

Create a txt-file (e.g. new_points.txt) that contains the approx. coordinates of the new (unknown) points. The order is <id> <east> <north>

 1 14185 7288
 2 13762 6403
 3 14659 6007
 4 11465 5631
 5 12203 5574
 6 13156 5553
 7 14213 5127
 8 15162 4876
 9 11849 4741
10 12583 4707
11 13653 4384
12 14552 4158
13 15388 4029
14 12193 3965
15 12990 3688
16 12582 3118

Create a further txt-file that contains the coordinates of your reference (known) points using the same format:


A 12641.506    6754.829
B 15731.413    5812.833
C 11416.224    3921.277
D 14040.478    3286.686


Now, you have to create the observation files. For directions, you have to create a single txt-file for each set of directions. For example: If you observed from station 1 the points A, 2, 3, B, the corresponding txt-file reads (e.g. directions_station_1.txt)

1 A    0.0002
1 2  349.5081
1 3  298.6079
1 B  269.6899

The order is <station id> <target id> <observation value>.

A further set of direction measured from e.g. station 2 reads (e.g. directions_station_2.txt)

2 1    0.0000
2 3   98.1536
2 7  150.0615
2 6  211.1281
2 A  291.0299

Create single files for all of your sets of directions.

If you observed distanced, too, just create a further txt-file (e.g. distances.txt):

1 A  1633.075
1 2   980.743
1 3  1366.205
1 B  2137.366
2 1   980.746
2 3   980.018
2 7  1353.068
2 6  1044.174
2 A  1175.304

(In contrast to the directions, all distances can be joined into a single file.) Some file specifications can be found in the doku-wiki.


Now, import these flat files to your JAG3D project and adjust the network.

Let me know, if it works or if you have further questions.

/Micha
