The compass feature can only be used when viewing 360 photo captures. This feature is available in all of AirMap's data viewers (TowerSight, JobSight, Etc.)
To utilize the Compass feature navigate to the data viewer of your choice and select the 360 photo data type.
Next select the compass icon() on the right hand side of the viewer
at the top of your viewer will be the compass heading. This heading will change based on which direction you are viewing in the 360 photo.
You can also click on a specific heading and the image will snap to that direction.
