A projection system that maps a spherical scanned image / capture onto an unwrapped cylindrical view.

Often used to convey a pictorial view of the world, in this context (panoramic image) the verticals remain vertical and the horizontal centre remains a straight line.

This format can be directly translated for further use within Panoramic authoring tools such as PanoWeaver.

The Spheron system automatically generates a tone mapped, equirectangular thumbnail preview for viewing convenience.
