Project the seven classical planetary lines onto a real Cesium globe. Calculate transits, secondary progressions, eclipse paths and stationary periods for any natal chart. The world map seen through the lens of Hellenistic astrology.
Astrocartography traditionally lives on a flat map: lines drawn where each planet would be on the angles (Midheaven, IC, Ascendant, Descendant) at the moment of your birth. This tool moves that idea onto a three-dimensional globe. You can rotate the Earth, zoom into a city, and see exactly which planetary line crosses which longitude.
Beyond the natal projection, the tool includes a cyclocartographic layer: the current transit positions of Jupiter and Saturn, the secondary progressions of the five inner planets, this year's profected house and its time-lord, upcoming solar and lunar eclipses with their paths of visibility, and the stationary periods when planets appear motionless in the sky.
The astronomical engine is the open-source astronomy-engine (VSOP87 ephemerides). Houses follow Placidus by default, with Whole Sign available for the Hellenistic reader. Sect detection (day chart / night chart) shapes the interpretive layer, distinguishing benefics by sect and identifying the time-lord of the profected year.
MC, IC, ASC and DSC lines for the seven classical planets on the globe.
Latitudes where two planets cross the angles simultaneously.
Live Jupiter and Saturn positions projected as lines today.
Secondary progressed positions for Sun, Moon, Mercury, Venus and Mars.
Annual profected house and its time-lord with sect-aware reading.
Solar and lunar eclipses in the next six months with paths of visibility.
Periods when planets appear motionless; Void-of-Course Moon windows.
Day/night detection, essential dignity (domicile, exaltation, triplicity, bounds, decans).
All planetary positions are computed from the VSOP87 theory via the astronomy-engine library, with topocentric corrections at the chosen birth location. The ascendant and midheaven follow Meeus's formulae; Placidus house cusps from iterative semi-arc calculation.
The interpretive layer is built on Hellenistic primary sources: Dorotheus, Carmen Astrologicum; Vettius Valens, Anthology; Hephaistio of Thebes, Apotelesmatica; and the medieval synthesis of Sahl ibn Bishr and Albumasar. Sect doctrine follows Hellenistic conventions: by day the Sun is the diurnal sect leader and Jupiter is its sect benefic; by night the Moon leads and Venus benefits.
This is a research and study tool, not a substitute for consultation with a trained astrologer. Astrocartography offers one of many useful lenses on a chart — never the only one.
