Interpolate matter with GPS correlator

[Photonoxx]

Hi,

I recently try to tag some photos with Digikam 2.0.0 rc installed with  
Philip5's PPA and Kubuntu backports PPA on Ubuntu 10.10 64 bits

I try to add coordinates in my pictures with correlator, and successfully  
set the offset(? décalage in french) between GPX and pictures time  
metadata, but some parts of the journey are missing in the GPX file, in  
consequence I set an higher value for "interpolate", but it has a strange  
behaviour and the main part of my pictures (took when there's some missing  
in GPX) are still not been correlated.

For example, in my GPX I have a point at 15h57m44s GMT (so 17h57m44s GMT+2  
in France) and the next one at 16h23m31 (18h23m31s).

I try to correlate four pictures at respectively 18h12m32s, 18h13m37s,  
18h14m03s, 18h15m39s, and interpolate is set to 60 minutes (time zone is  
manually set to +2 with a fine offset of -15seconds) , but correlator just  
find a match for the first one...

I try to edit the gpx file with GPSprune and add a point between and set  
manually the time and date for this point at 18h13m31s. With that it just  
correlate the two first pictures, but the two last ones still aren't  
correlated...

Is somebody had the same kind of behaviour here ? is there something I  
have mis-setting ?

If somebody want I can send GPX and pictures for testing

Thanks

Nicolas

Hi Nicolas,

sounds like a bug in gpssync. Can you send me the gpx file and some
pictures (you can resize them to save space) to this address:
[hidden email], I'll try to look into the problem.

Thanks,

Michael

Thanks for sending me the GPX file and associated images by private
mail. I found a bug in the time correlation code and fixed it:

http://commits.kde.org/kipi-plugins/64cd87598c53b68f337402393915c2ddfd2a6a04

Thanks for reporting this,

Michael
