Researchers have used archaeogeodesy and archaeoastronomy to analyze the placements, alignments, dimensions, and site-to-site interrelationships of the earthworks.
By historical astronomy we include the history of astronomy; what has come to be known as archaeoastronomy; and the application of historical records to modern astrophysical problems.
