#10235 assigned enhancement

Write GPSImgDirection based on direction of track

Reported by: mvexel Owned by: Don-vip
Priority: normal Milestone:
Component: Plugin photo_geotagging Version:
Keywords: Cc: holgermappt, lists@…

Description

It would be really nice if the geotagging plugin could calculate the compass direction from the GPS track and write that information to the GPSImgDirection tag of the EXIF spec.

(This tag is required to be present by Mapillary for uploading images.)

How does the direction of the GPS track correspond to direction of the image? Usually you would turn left and right to capture the houses along the street rather than the road straight ahead.

comment:2 by mvexel, 10 years ago

Good point. The use case would be sequences of images taken from a car or bike, where the heading of the camera relative to the driving direction would be constant. See my diary entry for more background.

Ok, thanks for the feedback. I think this is still a rather special use case. I will keep this feature request in mind, but don't expect anything in near future.

I am not :) Thanks for considering it. I just wanted to bring it to your attention. If I find some time, I will look into it myself.

Hello !

I'd like to ask a very close feature : The possibility to add and edit the gpsimgdirection.

Why ?

  • Sometimes, the direction is wrong and I'd like to correct it before sending the pictures on the mapillary website.
  • I have a lot of pictures captured with osmtracker, without the direction and I'd like to add it and then send these to the mapillary website.

This EXIF tag is no longer required for uploading images to Mapillary and Mapillary now also has functions that points the direction of images to the next image in sequences (basically everything mvexel asks for here).

I'm working on this in the photoadjust plugin. Some patches are needed to make this usable, so it might take some time until that feature is released.

Now i'm using the photoadjust plugin to add or edit the picture's direction (thank you holgermappt) , but I would be really useful to be able to add the imgdirection from the "correlate from gpx" window with 2 choices and 1 input box:
Choice :

  • add imgdirection : point to the next node in the gpx
  • add imgdirection : point to the next picture

Input box : Offset to the gpx direction (-359 to 359, default value = 0)

Any progress here? I badly need it for 10k images.

It's not the same when the sequence have holes in it

Note that osmand now supports to track the heading in an "extension": (Needs to be explicitly enabled in the settings of the tracker plugin)

      <trkpt lat="4X.XXXXXXX" lon="1X.XXXXXXX">
        <ele>XXX.XXX</ele>
        <time>2020-04-03T13:03:47Z</time>
        <hdop>7.504</hdop>
        <extensions>
          <speed>1.24</speed>
          <heading>233</heading>
        </extensions>
      </trkpt>

It would be really cool if the GPSImgDirection could be taken (and/or interpolated) from this data point.

And also, it would be nice to have a possibility to enter an offset angle, depending on how the phone is mounted in respect to the camera.
