Free astrocartography calculator
Astrocartography: your planets, drawn across the Earth.
At the minute you were born, every planet was rising somewhere, setting somewhere and standing overhead somewhere else. This free astrocartography map draws those places as lines across the world, then names the cities each one passes.

From the example chart
Your strongest places, line by line.
For each personal planet, the large city that sits closest to one of its lines. Read them as places to notice, not instructions: astrocartography describes a mood a place may have for you, and you are the judge of it.
Venus · Descendant line
Shenyang
Astrologers read Venus on the Descendant as ease, beauty and affection showing up in partnerships and close one-to-one connections. It is a place to notice what you find beautiful and who you warm to, not a promise of what will happen there.
Also near this line: Changchun, Suzhou
Jupiter · Ascendant line
Omsk
Astrologers read Jupiter on the Ascendant as growth, generosity and wider horizons colouring how you carry yourself day to day. It is a place to notice where you feel room to grow, not a promise of what will happen there.
Also near this line: Navoi, Toamasina
Sun · Descendant line
Bhopal
Astrologers read Sun on the Descendant as confidence and a clearer sense of purpose showing up in partnerships and close one-to-one connections. It is a place to notice when you feel most like yourself, not a promise of what will happen there.

Busan
Astrologers read Moon on the Descendant as comfort, memory and a feeling of belonging showing up in partnerships and close one-to-one connections. It is a place to notice what makes a place feel like home to you, not a promise of what will happen there.

Mercury · Descendant line
Lanzhou
Astrologers read Mercury on the Descendant as curiosity, conversation and learning showing up in partnerships and close one-to-one connections. It is a place to notice which ideas and conversations find you, not a promise of what will happen there.
Also near this line: Linxia, Pakokku
Mars · Imum Coeli line
Mudanjiang
Astrologers read Mars on the Imum Coeli as drive, courage and some friction settling into home, family and private life. It is a place to notice where your energy runs high and what you push against, not a promise of what will happen there.

How the map is drawn
Four lines for every planet.
Each planet gets the same four lines, named after the four angles of a birth chart. Together they show where on Earth that planet would have sat exactly on the horizon or the meridian at your birth.
MC
Midheaven line
Where the planet stood directly overhead, at the highest point of its arc. Astrologers tie it to vocation, reputation and the version of you that other people see at work.
IC
IC line
The opposite meridian, where the planet sat directly beneath your feet. It is read through home, family, roots and the private life no one else sees.
AC
Ascendant line
Where the planet was rising over the eastern horizon. It is linked to your body, your first impressions and how you carry yourself in a new place.
DC
Descendant line
Where the planet was setting in the west. It is read through partnerships, close collaborators and the people you tend to meet.
Planet by planet
What each planet line tends to symbolize.
These are the traditional associations. They describe a tone a place may take on for you, not events that will happen there.
Sun lines
Visibility, vitality and purpose. Sun lines are often described as places where you feel more like yourself, and more noticed.
Moon lines
Comfort, memory and belonging. Moon lines are linked to feeling at home, and to moods that run closer to the surface.
Mercury lines
Talk, study, trade and travel. Mercury lines are associated with busy minds, new contacts and learning.
Venus lines
Pleasure, beauty and affection. Venus lines are the ones people look up first: places linked to ease, art and warmth.
Mars lines
Drive, courage and heat. Mars lines can feel energising or combative; many astrologers read them as places to work hard rather than rest.
Jupiter lines
Growth, generosity and luck in the old sense of opportunity. Jupiter lines are associated with optimism and wider horizons.
Saturn lines
Structure, effort and time. Saturn lines are linked to responsibility and slow, serious work, which some people find steadying and others heavy.
Uranus lines
Change and independence. Uranus lines are associated with breaks from routine, sudden turns and a taste for freedom.
Neptune lines
Imagination and longing. Neptune lines are linked to inspiration, spirituality and blurred boundaries, for better and worse.
Pluto lines
Depth, power and transformation. Pluto lines are read as intense places that tend to bring hidden things to the surface.
Reading the map
How to read your astrocartography map.
- I
Start with your birthplace
The ember dot marks where you were born. Lines that pass close to it describe planets that were already angular in your birth chart.
- II
Follow one planet at a time
Tap a planet in the legend to bring its four lines forward. Its Midheaven and IC run straight from pole to pole; its Ascendant and Descendant curve across the latitudes.
- III
Look for cities, not exact points
Astrologers usually treat a line as a band a few hundred kilometres wide, strongest close in. We list cities of 100,000 people or more within 300 km.
- IV
Ask how it matched your experience
The most useful reading is personal: if you have lived or travelled near a line, compare what you remember with what the planet is said to symbolise.
How we calculate it
Planet positions come from Astronomy Engine, an open-source astronomy library: apparent geocentric right ascension and declination for your birth minute, measured against Greenwich apparent sidereal time. A planet's Midheaven line runs along the longitude where its right ascension matches local sidereal time; its rising and setting lines solve the horizon equation at each latitude from 66°S to 66°N. Coastlines are Natural Earth's 1:110m land data, and nearby places come from a database of cities with 100,000 or more people. Read the full methodology.
Questions people ask
Astrocartography, plainly answered.
What is astrocartography?
Astrocartography, sometimes called astro-cartography or astrolocality astrology, maps your birth chart onto the globe. At the moment you were born each planet was rising, setting, culminating or anti-culminating somewhere on Earth. Joining those places gives four lines per planet, and astrologers read each line as a place where that planet's themes feel louder.
Do I need my exact birth time?
Yes. The Earth turns about one degree every four minutes, so the whole map shifts east or west with the clock. A time that is off by half an hour moves every line by roughly seven and a half degrees of longitude, which can be several hundred kilometres. If your time is a guess, treat the lines as approximate.
How close to a line do I need to be?
There is no agreed cut-off. Many astrologers use a few hundred kilometres either side, with the effect said to be strongest within the first hundred or so. This calculator lists large cities within 300 km of each line and shows the distance, so you can apply your own orb.
Should I move to a city on my Venus or Jupiter line?
We would not make a move on a map line alone. Work, people, cost and language matter far more to how a place treats you. Astrocartography is better used as a reflective lens: a way to ask why a city felt the way it did, or what you might want from the next one.
Why do the Ascendant and Descendant lines curve?
The Midheaven and IC depend only on longitude, so they are straight north to south. Rising and setting also depend on latitude, because the horizon tilts as you travel toward the poles. Close to the polar circles some planets never rise or set at all on that day, which is why the curves stop short of the map's edges.
Is this the same in Vedic astrology?
The lines are the same. They come from where the planets really were in the sky relative to the horizon and meridian, not from zodiac signs, so tropical and sidereal astrologers draw identical maps.
How is this different from a relocated chart?
A relocated chart recasts your whole birth chart for a new city, changing the houses and angles. Astrocartography shows only the places where a planet sits exactly on an angle. The two are complementary; the map is the quicker overview.
Is my birth data saved?
No. Your birth details are sent once to calculate the lines and nearby cities, and nothing is stored.
