Base coord origin, and rtk-ppk sideshot selection

This is in DPOS

Our base coordinate origin, can be:
Autonomous
CORS fixed
M-Local (or 1-Local)

Then, FROM this BASE coordinate, we do all out surveying.
And, those side shots, can be RTK, or PPK.

-------------------------------------------------------------------
OPTION A
Here is what is happening:
When we set the base origin to be CORS, and then look at the sideshot coordinates,
we can select RTK, OR PPK, as we wish.

We get a popup, that has 3 options.
1.) Select the PPK coordinate for this point only
2.) Select the PPK Coordinate for ALL points
3.) Auto Select the best RTK/PPK for all points.

This is GOOD, and how it should be.


-------------------------------------------------------------------
OPTION B
When we set the base origin to be 1 LOCAL, and then look at the sideshot coordinates,
we now have ONE LOCAL as an option....
(Which should not be an option, as that should only be an option for the base point).
So, we now have these 3 options, but, should only have 2 options here, and we select RTK, and we get a popup, with 2 options.

1.) Select the RPK Coordinate for ALL points
2.) Auto Select the best RTK/PPK for all points.

But, we should have a popup identical to the one for OPTION A.


---------------------------------------------------------------------------------

I feel that NO MATTER what the base origin is, we should be allowed to select RTK, or PPK, as we wish.
Auto select is ok, but when there is a difference, between these, we should have an option, to "LOOK AT ALL POINTS, with a difference of greater than _________ (User select-able value) , and here, we look at ONLY the points with a significant difference. It would even be better, if we had an option, for



Difference <greater than> 0.30 ft_____ shows up RED. (Worst offenders show up first, and then progressively, by order of magnitude)
Difference <greater than> 0.15' _____ shows up GREY (Worst offenders show up first, and then progressively, by order of magnitude)
Difference <greater than> 0.08'_____ shows up BLUE (Worst offenders show up first, and then progressively, by order of magnitude)
DIfference <greater than> 0.05'_____ shows up green (Worst offenders show up first, and then progressively, by order of magnitude)

RED is the worst difference.
GREY is POOR.
BLUE is tolerable, but not too good.
and, GREEN below all this. (These are
Now, these values should be user select able, but perhaps these can be default values.

By doing this, we can set up a project, to look at what is critical first.

What I'm afraid of, is accidentally overlooking a point, that had an RTK/PPK difference, that was critical, and missing it. This organization of looking at the way coords are created, will help prevent it.
This RED-GREY-BLUE-GREEN filter, should be under DPOS, and should simply be an option, so that we improve our efficiency when viewing results of our work.

I'm sure that this list of ideas could be improved upon, but I'm just throwing this on the site, for discussion, and as raw material, for the production of a better program.

Thank you,

Nate

I would also like to choose to export both the RTK and PPK solutions for points of my choosing. ie. - If I know my point is in a nasty position, however, I have additional data (field measurements, etc.), and JAVAD chooses RTK as the best solution, PPK disagrees with RTK by feet, observation is 20 minutes+, I want to easily download and plot both solutions. Say export point 201R and 201P (RTK and PPK).

Same stuff-different day. We need to be able to evaluate the data and manipulate our choices as the project develops, and we start comparing our field data/choices with deeds and additional shots, or measurements, and after we have sent the LS back to the field.

I know I am beating this horse long after its death. Sorry.

The current plan is to add indicator and toggle button for the vector solution type at bottom of M-Local column:

What I've run into, is that m-local (or reverse-shift) removes part of the freedom, to choose the sideshot type. Ie, RTK for some, and PPK for others. It forces you to do all ppk, or rtk.

Whereas, the base's origIn should have no influence on your choice RTK/PPK, for your sideshots. (base to rover).
Does the above change, allow ppk/rtk mix as needed, with m-local?

Thanks,
Nate

Ok... I replied earlier with my phone... (tiny keyboard)
Will I be able to select 1 local, and RTK Fixed, and 1 local, or PPK fixed, in the same session? It seems maybe so...

We have an option to export all coordinates for a point as separate points currently with the "Save Aux Coords as Separate Points":

EXPORT-CSV-SETTINGS_20171019-10.51.54.png


This will export many coordinates for each point, more than you want. @Mikhail Drakin could probably add more configuration options to this feature so that only the RTK and PPK coordinates for the current selected base coordinate could be exported.

I'm afraid we'll end up having full set of checkboxes (how many coord types we have, about 17?). Probably it would be better to use destination software to filter by coordinate types needed.

I was thinking we just need a configuration screen for the "Save Auc Coords as Separate Points" button. It could be opened with a long click of this button. Then it would only need a checkbox to " Export only RTK and PPK coordinates for the current selected base". Then also an option to append some text string to the point name for each of the two cases.

On the subject of exporting csv's.
Would it be alot of work to:
Add check boxes for:
Export rtk
Export ppk (add prefix/suffix)
Export average of ppk/rtk (add prefix/suffix)


And, under cluster average, a check box, to include ppk in avg solution, (add prefix/suffix)

I really don't know how much closer to "the absolute truth", those might bring us... (if any). But such thoughts wander up, and down, in my cerebal cortex!
