Please show an arrow towards the direction (heading) of the camera for images #10

We would see great use from that for our OpenStreetMap volunteering efforts.

Hi, thanks for the suggestion. This is now implemented in a very simple fashion. There's an arrow in the picture popup. image I'm not sure about the trust we can put in camera sensors involved when determining the direction. I've used a bunch of pictures from an old phone and the direction appears to be very wrong. Anyway, the exif property GpxPod now gets and shows is GPS:GPSImgDirection. After reading a bunch of docs, I'm quite confident it is the clockwise angle relative to north, in decimal degrees.

This will be available in the next release which is coming soon.

In the meantime if you have a bunch of non-personal pictures with the bearing or direction set as exif properties, I would be interested to use them for test purposes.

Thank you. Be our guest:

We usually go through our images within the JOSM photo editor plugin to drag & drop each image in its correct place and adjust its heading as well.

Thanks a lot for the photos. They were useful as they showed there are different direction formats. So far I've seen 2 of them. They are now supported.

within the JOSM photo editor plugin

Which JOSM plugin are you talking about? photoadjust, photo_geotagging or another one?

Btw, if you have a test instance, it would be awesome if you could try the latest nightly build: v5.0.7-2-nightly
