Azimuth Only photo station setup type

One of four setup types that can be applied to a terrestrial photo station that determines how the station will be adjusted during a tie point adjustment. Specify this setup type for a photo station when you want the station's compass value to be adjusted while constraining its tilt and position values.

This setup type requires only two to four tie point observations and is useful if you want to include photo-observable backsights to improve the station's compass value before performing an automatic tie point adjustment.
