GeoEasy 3.1.3

Source: 20210205-3st.sdr (gnu-gama-3st-2K.zip)

sheme

Construction network from Resection (3 stations). Cannot calculate or export to GNU Gama. GNU Gama itself processes the data.

Does it solve? https://github.com/zsiki/GeoEasy/commit/c260dc88f8ef19fc92feee0be501ea1996480a7c Before this commit you have to save the SDR input to GeoEasy format and load that.

Hi @zsiki .

I can't check now. I'll try on Monday.

Calculate -> Orientations
Info: Orientation cannot be calculated for any station

zvezdochiot commented 3 years ago

GNU Gama Export ok.

I loaded 20210205-3st.sdr and selected Calculate/Orientations and I got:

Some coordinates are false but calculation works.

@zsiki say:

Put ST1, ST2 and ST3 in "coarse". Does not work.

zsiki commented 3 years ago

What does "coarse" mean in this case. If you erase the coordinates of ST1, ST2, ST3 or make them preliminary, no way to calculate orientation on these points without the station coordinates. On the other hand this is not a network, no sense to use network adjustment.

zvezdochiot commented 3 years ago

@zsiki say:

From the classical point of view, it is not a network. But! This is precisely the modern standard serif construction network. Ce-La-Vi.

zsiki commented 3 years ago

It may be modern but not rigid enough. I would make observations between ST1-ST2 and ST2-ST3.

In most cases this is not possible.

PS: Is it possible, when exporting to GNU Gama, not to write "rough" coordinates to points. Then GeoEasy would at least be a converter for such tasks (see https://github.com/zsiki/GeoEasy/issues/151).
