Your birth chart describes a moment. Astrocartography asks the other half of the question: where on Earth was each planet doing something at that moment. Give it your birth date, time and place, and the map draws four lines per planet — where it stood at the top of the sky, at the bottom, on the eastern horizon and on the western one.
Enter your birth data and the lines appear on the map.
The meridian where the planet stood highest in the sky. Read it as the public line: what a place lets you be known for. On a Jupiter MC line the same skill you have at home tends to read as more credible — you get given room.
The opposite meridian — the planet at its lowest point, under your feet. The private line: home, family, roots, the part of life nobody watches. A Moon IC line is where people say a place «felt like home» before they could explain why.
The arc where the planet was rising. Its quality becomes your first impression — how you come across before you have said anything. On a Mars ASC line you read as more direct than you feel.
The arc where the planet was setting. The line of other people: who finds you, what kind of partner and counterpart turns up. A Venus DSC line is the classic «I met someone there» story.
Distance is the whole message. Standing on a line is the strong case, a hundred kilometres away is still clearly it, and past a thousand kilometres that planet is simply not the story of that place. The map draws two corridors — 1° (about 110 km) and 3° (about 330 km) — so you can see the strength instead of guessing at it.
Nothing here is a verdict. A line tells you which planet is loud in a place, not whether you will be happy there. Saturn loud is not a punishment: it is the kind of place where work counts and shortcuts do not.
Lines are drawn from the real body in the sky, with its latitude, the way Jim Lewis drew them and the way Astrodienst draws them. That matters most for Pluto, which can sit 17° off the ecliptic — far enough that the two possible conventions put its lines thousands of kilometres apart.
Moving does not move the planets. It moves the horizon. Recalculate your birth moment for a different city and every planet keeps its exact position, while the angles and the houses shift — which is why the same chart can put the same Saturn in the house of work in one city and in the house of home in another.
That is the honest way to check a line before you buy a ticket: read the relocation chart for the actual address, not just the coloured line running near it.
A birth line does not move. What moves is the sky above it: when a slow planet — Jupiter, Saturn, Uranus, Neptune or Pluto — reaches the midheaven or the horizon of one particular city, that city has a season rather than a permanent quality. The map dates those seasons, so a place that is yours for life can also be loud this autumn and quiet for the three years after.
The same question comes at you from two sides. Tell the map what the trip is for and how long you have, and it answers with places: which of your lines are open in those days, and how far each city sits from one. Name a country instead, and it answers with a calendar — which of its cities open, when, and what to do if none of them opens this year. That last part is only sayable because the calculation covers five years even when a single one is on screen.
Neither is a forecast of events. A window says which part of the chart a place puts in front of you while it lasts; what you do inside it is not written on any map.
Astrocartography is a world map of your birth chart. For each planet it draws the places on Earth where that planet was at one of the four angles at the moment you were born — culminating overhead (MC), at the lowest point (IC), rising on the eastern horizon (ASC) or setting on the western one (DSC). The technique was developed and named by the American astrologer Jim Lewis in the 1970s.
Yes. The map is free and needs no account — birth date, birth time and birth place are enough. The relocation chart for any city on the map is free as well.
For this technique, more than anywhere else. The whole map turns 15° of longitude for every hour, so an hour of error moves every line about 1,600 km at the equator — a different continent, not a different suburb. Ten minutes of uncertainty is fine; an unknown birth time is not.
No. Lines read on visits too — a two-week trip across a Venus line is a well-documented experience, and one of the standard ways people first notice the map is real. Living on one turns the same influence into a permanent condition, which is a much bigger decision than a holiday.
Almost always because of one choice: whether a line follows the real body in the sky (in mundo, with its latitude) or its projection onto the ecliptic. StarMeet uses the first, like Jim Lewis and Astrodienst; some sites default to the second. On the Sun and Moon the two agree; on Pluto they can differ by thousands of kilometres. Our own lines were checked against an independent Swiss Ephemeris engine in August 2026: the MC and IC meridians agree to within 420 metres.
A relocation chart recalculates your birth moment for a different place on Earth. The planets stay exactly where they were — only the ascendant, the midheaven and the house cusps move, because the horizon of the new place is different. It is the standard way to read what a city does to a chart.
Yes, and it is a different measurement rather than a softer version of the same one. A birth line is permanent; a transit is dated. When a slow planet reaches the midheaven or the horizon of a city, that city is lit for weeks or months, and the map lists those windows with their dates. Five slow planets only — Jupiter, Saturn, Uranus, Neptune and Pluto: the fast ones pass through in days and would fill the list with noise.
That is what the destination mode is for. Pick a country and the map reads all of its cities at once — the United States is forty-nine of them once neighbouring cities are folded together — and answers with a month-by-month strip and a dated list. If nothing opens inside the span you chose, it says so and names the first date beyond it. «Nothing this year, and the next is in 2028» is an answer; an empty screen is not.
