Time interpolation

[paw3lk]

Hi,

I've just been playing around with RC as I'm looking for a solution for adding interpolated points to GPS tracks (GPX). Some of my tracks are of not very good quality - too few points, so I need to add some in between which is not a problem since it's all streets and roads. I can accomplish that easily using RC. The problem is that I also need interpolated time for picture geotagging purposes. Interpolated time is not ideal but better than no time info at all. RC seems to copy timestamp of preceding point.
Is there any way around it?

Also, RC adds <name> information automatically to each track point even when it's not in original file. To me personally all it does is makes output file bigger as I don't need these point names. Any way to turn it off?

thanks

You can always modify the time manually. I could change the time of new positions to be the average of the preceding and following position if that helps. In the end it's a heuristic...

Yes, have a look at the hidden options. For Windows and GPX it's

[HKEY_CURRENT_USER\Software\JavaSoft\Prefs\slash\navigation\gpx]
"write/Elevation"="true"
"write/Name"="true"
"write/Speed"="true"
"write/Time"="true"

that allows you to reduce the amount of data.

Yes this is precisely what I would love to see. Surely I could do this manually but it would be very laborious and error prone.

Great, thanks

I forgot it, but that's what is currently implemented.

OK the link does not make too much sense to me but I trust it's being implemented
Much appreciated.

It was implemented but with a subtle bug which set the time of the inserted position mostly to the time of the preceding position. Please use the prerelease for the desired behaviour.

Just to be sure - current pre release version has this bug or some previous one?

The prerelease has the bug fixed.

OK thanks a lot for that, it will make a huge difference to me.

And one more suggestion - my original GPX file has track segments names but no point names. Using your hidden options I can either enable all names or disable all names, there is no way to keep track segments names only. Not a big deal, a suggestion for future.

Thanks

Hello. I rescued this old topic.

As in the first post, I would like to fill in unknown point times between two points with known time.


How can I do the time interpolation? I don't find the option in RC.

Thanks!
