1. Embed latitude, longitude and azimuth in the geotag of the photographic image
With a normal camera app, you can only write latitude and longitude to the geotag of a photographic image. "Angle Camera" can write the azimuth (shooting direction) in addition to latitude and longitude to the geotag of the photographic image.
You can also display the tilt angle of your smartphone when shooting. "Angle Camera" can confirm the information with a message after taking a picture.
