Popis:	Photographs of the sky, taken through a fish-eye lens with a 180° field-of-view in several environments, were analysed for the skyline, a quantity useful to designers of mobile satellite communications systems. Above 10° elevation, on average 98% of the sky is visible in rural, 95% in suburban, 77% in urban Austin, and 68% in urban San Antonio.
