# JAG3D Deformation monitoring of sites. (Geodäsie/Vermessung)

Hi Jokin,

No Problem!

it is hard without knowing the meaning of some of the variables. Anyway, I think that I will be able to sort it out.

Okay, thats a point. I will explain the table header. Your work with the english version?

Raw-Table (Observation)

Instrument-ID = The point id of your Instrument
Target-ID = The observed point
ih = Instrument height (Default = 0)
th = Target height (Default = 0)
δz, t0, sh0, sr0, v0 = Observation (leveling, direction, distance 2D, distance 3D, zenithangle)
σ0 = a-priori standard deviation (override group-settings)

Result-Table (Observation)

δz, t, sh, sr, v = estimated Observation (leveling, direction, distance 2D, distance 3D, zenithangle)
σ = a-posteriori standard deviation
r = redundance
∇ = estimated gross error
EP = (1-r)*∇ (I don't know the English phrase)
∇(α,β) = boundary value to detect an outlier (in Germany also called as GRZW)
Ω = sum of squares
Tprio/Tpost = test values for outliers detection with respect to the Fisher-distribution
Outlier = true, if Tprio or Tpost were rejected


Result-Table (Points)

(σ, ∇, etc. same as above)
...
A, B, C = semi-axis of the confidence-ellipsoid
α, β, γ = rotation angle of the confidence-ellipsoid
...


I want to use the GAMA software to compute the network solutions.

For classic observation, GAMA produces the same results as JAG3D e.g. Vergleich der Ergebnisse verschiedener Netzausgleichungsprogramme. Anyway, if it is possible to get your raw-data, I will re-calculate your network with JAG3D, too. If you can give me some more details to your deformation-task, I can answered more tightly focused.

If you want to email me, you can contact me here (notice: every field is mandatory).

kind regards
Micha
