Save for Post Processing

With a check box, at the bottom of the screen, after pressing "Accept As".
I had it checked.
But, it did not save for post processing.
I asked Shawn about it, and said he had not used it.
So, I wondered, what does it do, or what is it supposed to do?
Thanks!

It still works correctly when I tested it. When it is checked, after the Save As point is accepted, it will be flagged "Marked Process (MP)" so that the base-rover vector will always be processed when sent to DPOS.

Did you have the "RAW GNSS DATA" unchecked, in your action profile? (as I did)?

I just tried this and it still was working correctly in this case. When you say it was not saved, what are you referring to? The point wasn't saved, the raw data wasn't saved or it wasn't flagged "Marked Process (MP)"?

Raw data is not saved. It seems that I am entangled in the nomenclature.... What is "Marked Process (MP)"?
The note at the bottom of the screen says "SAVE FOR POST PROCESSING".
Does this not require RAW DATA?
thanks!

"Marked Process (MP)" is one of the point Process Type attributes that can shown when the "Type Filters" is shown in the Points screen. Taping the Type Filter button shows the various attributes that a point can have:

If a point is Marked Process then the Base-Rover vector will be processed when sent to DPOS regardless of rather "Process all Points with raw GNSS files" is checked. Raw data is required for it. Check to see if your point was Marked Process in the points screen.

OK, so "Marked Process" is checked, but no raw data is stored.
Where does this leave me?
IF I had raw data, but did not have MP checked, then what? Well, it would process the raw data.... this seems like an odd step.
What purpose does it serve?

It is a bug if the raw data is not being saved. Are you able to repeat it? Like I said, it works correctly when I tested it. Try collecting another point with it checked and confirm that raw data is not saved. Also if you use the "Save for PP" button in the stake action is raw data being saved?

No Raw Data. So, it is SUPPOSED to trigger it to save the raw data for that shot?
Good! That's what I thought it was doing.
And, NO, Raw data is not there.
So, my assumption was right, and there is a bug there.
Ok. good enough.
Do you need anything from me?

MP means that it will upload and process that file regardless of whether "Process all Points with raw GNSS files" is checked or not. Sometimes you may have a lot of raw files, but you don't need to process them. You can mark some for processing that will be processed while ignoring other points that have raw data that are not marked for processing.

This button in Stake Out makes no sense to me anyway. If you want to store raw data, we have profile options that do that. Either guaranteed, always stored or conditional, if all conditions weren't satisfied, you get the option. I don't know what the button in stake out is for.

The purpose of the option is to allow raw data to be stored and the point flagged MP when using the Accept As button. Darren had requested this a while back.

Nate can most a dropbox or google link to the project archive or email it to me.

I use a profile that always stores raw data when using stake out, Accept As (What To Record>Raw GNSS Data). I can see that if the user has Activate Post Processing option after turned on that this button would be necessary. In Nate's case, he was using a profile that did not have APP turned on. Is the behavior of the button supposed to be that it stores a raw file even if APP is off?

Yes, it should save the raw data file regardless of rather it is checked in the What to Record screen, the same way as the "Save for PP" does in the action screens.

It should be gray or not appear in such cases. Nate used a profile with no raw data recording option check. Neither "what to record" nor "activate post processing option after", but the button still gave the option to store raw data (that did not exist).

I haven't tried the "save for post processing" button attached to the accept as yet. I will today if I get a chance. I always have the same profile set in my stake screen as I do in my collect screen so I'd have my PPK set for 15 minutes.
I know not many do a lot of "collect" while in "stake" screen but we do that quite a bit and I think Nate does as well.
The reason I can use this feature is we almost always have design points we are staking to and let's say I've translated and rotated a batch of 20 points on an existing survey from a known local surveyor who's work is typically very good to follow. After I get a few points, I'm consistently tying into his points within very reasonable tolerances. Then I get to one down in a deep dark hole, that's where I like to be in the stake action screen instead of collect. If my first couple of epochs gives me a DTT of 3.5', I'm pretty sure that's wrong. Then a couple more come in and my DTT changes to 6.4' - still not it. Finally after a few minutes I might get a bucket of 3,110,2 and my DTT will change to 0.13' or something similar. I immediately know that is the correct coordinate. This just gives us immediate feedback in the field - both of how "tight" the survey we're trying to follow is and if we already know it's good, it gives us more confidence quicker when the shot is harder to acquire. If that shot ends up taking 15 minutes, then I wanted the ability to store that raw data as a PPK point. The LS was already collecting it - I just couldn't use it until the feature was changed.
Another situation where we use this is staking to line. Sometimes those shots as well may take a long time and I like to store the coordinates of the stakes I set and the same thing applied. Before, I couldn't use/store any of the raw data collected while in stake mode - now we can.
This is what's so fantastic about this equipment, not everyone uses it exactly the same. There's definitely more than one way to skin a cat with the LS!
