Distance and bearing to Photo Point

Question

I have designed my survey so that I take multiple photos of a site, through repeats. I would like to have all of my photos calculate the direction and bearing to the first photo.

Can this be done through the Exif.GPSInfo.GPSDestDistance and the Exif.GPSInfo.GPSDestBearing tags?

If so, how would I designate the first photo as the "Destination Point", to which the distance and bearing are measured? If not the first photo, can I designate the geopoint as the Destination Point (which would essentially be the same as my first photo)?

Hi. You cannot get the distance to a point using the device's built-in camera.

I suggest you look at the Spike integration with Survey123. More details at:

You can get a rough bearing using pulldata("@exif", ${image}, "GpsImgDirection")
