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
