How astrocartography works
At the moment of your birth, each planet was at a specific point in the sky. But that point looks different from different locations on Earth. In one city, your Jupiter is at the top of the sky (MC) — and you are lucky. In another — below the horizon (IC) — and expansion happens in your inner life, not in the outer one.
Four types of lines
Astrocartography calculates 4 types of lines for each planet: AC (Ascendant — personality), DC (Descendant — relationships), MC (Midheaven — career), IC (Nadir — home and roots). Up to 40+ lines on the world map, each with its own meaning.
Natal chart relocation
Relocation is the recalculation of a natal chart for a different location. Planets stay in the same signs and degrees, but houses and Ascendant change. This shows which life areas are activated upon relocation. Relocation and astrocartography are two complementary tools.
Swiss Ephemeris — professional precision
Calculations are based on Swiss Ephemeris — an engine developed by Astrodienst (Switzerland). NASA/JPL data, accuracy to the arc second. The same standard used by professional software costing $200+. Free calculators often produce errors of several degrees — for world map lines, that means hundreds of kilometers.
