Archaeogeodesy encompasses prehistoric and ancient place determination, point positioning, navigation, astronomy, and measure and representation of the earth and geodynamic phenomena.
Distance is constant except for the negligible influence of plate tectonics. Site-to-site arc distance remains fixed in landscape reference. In contrast, secular polar motion alters the actual latitude of almost all geodetic positions on the planet, very slowly changing latitude at a local rate. The change in latitude due to secular polar motion is very slow compared to the temporal change in latitude-determined solar and lunar illumination angles, a function of angle of inclination of the axis

Highlights of abuses of astronomy in archaeoastronomy.
There is a growing fashion of using supposed astronomical evidence to validate claims for lost civilisations (LC), remarkable foreknowledge of astronomical events, etc. There is also the recurring crud about planetary alignments causing cataclysms on Earth.Almost all of this is just plain wrong and the so-called evidence from astronomy is usually hopelessly inaccurate. This part of the web site will, as I have time, try to correct some of the misinformation that is promulgated by the various
