auto-geotagging of "positionless" points about gpicsync HOT 5 CLOSED

Hello Harry,

I'm not sure exactly what you mean by "positionless" waypoint.

GPicSync use a gpx track log with "track points" which are automatically 
recorded
(typically each few seconds, 5 seconds on my Garmin).

Since it's always a good idea to avoid to "move" to take a good picture the
synchronization works very well in this case. There are also some
travelers/photographers who choose a GPS mode which record a trackpoint only 
when not
moving which means a potential picture (obviously interpolation is not a good 
idea here).

At the very beginning I had an interpolation mode but it didn't give me better
results as a whole, sometime better on some picture if I was moving fast on my 
bike,
sometime worst.

I prefer to keep a real measure by default since human behavior (unlike physical
phenomenons) is highly unpredictable between two measures (at list it avoids to 
find
myself in a river after a sharp turn  :) ).

Never the less if you move fast in a car or plane an interpolation is surely 
more
useful (I'll probably add an interpolation option in next versions then).

In the meantime I've heard gpsPhoto have an interpolation mode (and probably 
others):

Hi Francois!
on one hand you´re right. Normaly you have to stand for a while to take a good 
picture. But an the other side you will have some problems if you take shots in 
a 
car or plane. I think for the last two reasons it´s recommended.
But I have an "older" Garmin and I have to use my memory wisely. So I use the 
option 
of my Garmin for less points to get the whole trip. So it´s not unusual to 
have more 
than 5 sec between two points for me  - it goes up to more than 1 min! 
depending how 
I travel. Driving in a car with no turning (e.g. Autobahn) will result only a 
few 
waypoints and hiking with a lot of turning will result more waypoints to 
descripe 
the trip.
With positionless I mean waypoints which are "very off" to the last/next 
waypoint. 
That´s why I think its important to have a option to interpolate.

Ok I'll add an interpolation checkbox soon but please don't drive yourself while
taking pictures  ;)

Ok, I've added the feature in the SVN.
There is now  a checkbox in the interface called "interpolation" which use a 
linear
interpolation mode. 

If will be also available in the next build/release in 2 to 3 days I imagine 
(maybe
before).

Done in version 0.94. Thanks.
