Camera Angilator

How high is the Moon in the sky?
How tall is that distant mountain?
What direction is that building from here?
Where was I when I took saw that?
Does the horizon really rise to eye level?



This app overlays your GPS location, altitude, time, date, compass heading onto the camera screen, and lets you take a photo like that.



It also puts the tilt and elevation angles right on the screen. You can use the elevation angle to calculate the height of objects and even verify the curvature of the Earth.
