Visibility Tool For IOS This visibility tool enables users to turn their smart phone into a cutting edge meteorological sensing device. Once downloaded, the simple point-and-click capability enables anyone globally to determine local visibility, even in flight. The technology works by pointing the mobile phone camera towards the horizon and then angling up until the view is unobstructed by buildings, trees or other foreground objects. Users take a photo in any direction they want and the technology responds with a visibility metric ranging from 1-10+ miles (1.6-16+ kilometers).
