I have noticed that in adjustment and deformation analysis for example for 1D height of zero epoch or (Z0 like import data in adjustment) of some point for example is Z0 = 100.00 and after processing is Z = 100.15 (calculated).

Yes, this is possible. Please note, datum points are unknown (new) points, too. These points are estimated within the adjustment process. If the geodetic datum is defined as an average value of several points (instead of some kind of minimal configuration), the datum points get (small) corrections. The size of the correction depends on the quality of the datum definition. In a leveling network, only a single point is needed to define the datum. If so, this (single) datum point will not corrected, i.e., Δz ≡ 0.

In Δz is value of -0.15, Why software sees that point has settlement because there is minus 0.15 but actually point have uplift because new height is 100.15 that mean it is higher for 0.15.

In geodesy (at least in Germany, maybe, you can give me some feedback), we distinguish between an error ε and a correction v. The absolut value is identical, i.e., |ε| ≡ |v|, but the sign is differ: $\hat{l} = l + v = l - \epsilon$.

Points that define the datum are not part of the observation space. Thus, no error can be estimated. However, some users asked me to add some kind of metric that indicates the differences between the a-priori values and the estimated a-posteriori values. Since JAG3D provides the error ε for the observations, the same definition is used for the estimated differences Δ. It seems to be more consistent.

Is that only problem in settings

No, it is just a convention like for the error and the correction. If you need the correction instead of the error, please swap the signs mentally.

Is possible with that software to do pre-processing of network, if is yes do you have some tutorials?

Can you explain, what pre-processing means in your context.

kind regards

Is that only problem in settings, do I need somewhere to put for deviation calculation to be Z-Z0? Not to be like now Z0-Z because that is little confusing. (Z is currently calculated in software, Z0 is imported as known)

Thanks a lot!

I have read on website that is B method but I am not sure what is that.

The B-method (or β-method) was introduced by the pioneer work of Baarda, cf. A testing procedure for use in geodetic networks. It describes a procedure to adjust the α-level (type-I error) based on a joint test power (type-II error). JAG3D supports three methods to adjust the significance level. If you don't like to use the B-method, just select your preferred method, cf. Main menu --> Properties --> Test statistic.

Can you tell me which method is used for deformation analysis and congruence points? Is Karlsruhe, Pelzer...,

The method implemented in JAG3D is described in detail in Kongruenzanalyse auf der Basis originärer Beobachtungen. In contrast to the Karlsruhe or Hannover (Pelzers) approach, which based on preliminary results of (at least) two independent free network adjustments, JAG3D combines the original (raw) observations of both epochs in a joined network adjustment. Like the Karlsruhe approach, JAG3D uses explicit hypothesis tests to detect and to identify possible deformations. From this point of view, it is more related to the Karlsruhe approach.

Kind regards

Thanks for your answer.

I need that information to put in my reports which method is used.

Thanks a lot.

I have tried with tutorial which is on website. But I couldn't get information of deformation in datum points.

You have to enable the option congruence analysis in the least squares setting dialog.
