Astrocartography maps where each planet sat on an angle — the Ascendant, Midheaven, Descendant or IC — at the moment you were born, drawn as lines across a world map.
The lines are computed from real sky positions, so they are identical under sidereal and tropical zodiacs — your ayanamsa does not move them. What Vedic astrology adds is the interpretation: what that planet actually promises in your chart, and when.
The lines themselves are astronomical and identical in both systems. Vedic astrology supplies the interpretation — what the planet promises in your chart, how strong it is, and which dasha is running.
Latitudes where two planets are simultaneously on angles. A paran runs right around the globe, so every place at that latitude shares it regardless of longitude.
No. A Jupiter line amplifies whatever Jupiter actually does in your chart. If Jupiter is weak or rules difficult houses for your ascendant, that is amplified too.
No. Lines derive from right ascension and declination — real positions in the sky — so Lahiri, Raman and tropical all produce identical lines.
Occasional emails when something genuinely moves — eclipses, retrogrades, dasha shifts — written the same way as these articles. No horoscope spam.
