Geodetic

A geodetic chart is one whose house cusps are calculated with respect to the longitude and latitude of the birthplace, but not the actual birthtime. Each degree of geographic longitude is understood to correspond to a specific degree of the zodiac, which in turn serves as the midheaven of any chart calculated for that degree of longitude. From that midheaven, the ascendant and intermediary house cusps of the chart are then derived.

Charts relocated geodetically are used in mundane astrology and figure prominently in current earthquake research.
