Sacred Directions at Mac App Store analyse

Much is revealed by the geometry and alignment of archaeological sites. Throughout history, civilizations have considered certain directions to be significant and even sacred. These directions include north, south, east, and west - the cardinal directions, the directions in which the sun rises and sets on the summer and winter solstices, and the directions of extreme motion of the moon known as lunar standstills. Sacred Directions is the first app of its kind that plots these directions on a satellite image over any site, at any location on Earth, and shows how they change over time.
