Automate the distance bearing from geopoint

ParksBrian

In my survey, I would like to take a photo and then automatically calculate the distance (meters) and the bearing to the geopoint that is recorded for the site. Currently I just have the distance and bearing as text boxes to be filled in manually. Can these be automated?

Not sure on bearing but here is the code to calc distance in meters between any two lat/long pairs.

round(acos(sin(${Northing} * pi() div 180)*sin(${DesignLat} * pi() div 180) + cos(${Northing} * pi() div 180)*cos(${DesignLat} * pi() div 180)*cos((${DesignLong} * pi() div 180)-(${Easting} * pi() div 180))) * 6371000,2)

Hope that helps
