I was wondering why the projection option 3d reduction had disappeared in the newer versions, while it was integrated in v3.5.20170423 for example.

This module war replaced by a more rigorous mathematical model, i.e. the deviation of the vertical can now be estimated within the adjustment process. Using the current version of JAG3D, you can estimate the position [x/y/z] as well as both vertical deviation angles. You have to enable the option "*Consider deflection of the vertical*", see screenshot. In most cases, the deflection of the vertical can only be estimated for station points, especially, if target points haven't an instrument height.

kind regards

I thought I could ask you a question here, as the answer may be interesting for other people.

I was wondering why the projection option 3d reduction had disappeared in the newer versions, while it was integrated in v3.5.20170423 for example. I see that instead, you have integrated vertical deviation correction, but is there any tool in JAG3d that can help us to calculate a vertical deviation model? (spherical for instance)?

Thank you anyway for the great work you've achieved.
