Free Astrocartography Chart Calculator & Map
Generate your astrocartography map, understand what each line is emphasizing, and anchor those lines to real cities you can actually evaluate. No sign-up, no email, and no guesswork about what the map is trying to say.
Exact birth time required. Powered by NASA JPL ephemeris data for precision.
Interactive map
Generate your planetary lines and inspect any location on the globe.
Real-world context
See notable cities near each line so the map feels immediately usable.
Guided interpretation
Understand the angle, planet, and distance instead of staring at raw lines.
Enter your birth details once, then explore the whole world.
This calculator works best when the input is precise. If you have a birth certificate or hospital record, use that time.
Bring an exact birth time
Astrocartography is angle-based, so even small time errors can move the lines.
Explore cities, not just lines
The tool connects your map to nearby places you might already know or be considering.
Click anywhere to inspect
Use the map like a research surface instead of trying to interpret everything at once.
Understanding Your Astrocartography Lines
The map becomes much easier to read once you break each line into three questions: what part of life it touches, what kind of energy it carries, and how close you are to it.
Start with the angle
The angle tells you where the energy lands first: career, home life, identity, or relationships.
Then add the planet
A Sun line feels very different from a Saturn or Neptune line. The planet describes the tone of the place.
Check how close you are
Lines are strongest close to exact. A city a few hundred miles away can still feel relevant, but usually more softly.
The Four Angle Types
Each line shows where a planet was angular at the moment of your birth. The angle tells you which part of life the place tends to emphasize first.
MC (Midheaven)
Career, reputation, ambition, and how visible your work becomes.
IC (Imum Coeli)
Home, roots, family patterns, and the quality of your inner foundation.
ASC (Ascendant)
Identity, self-expression, vitality, and how you come across to other people.
DSC (Descendant)
Partnerships, collaborators, clients, and the kinds of people you draw in.
Distance Bands
Within 150 miles (240 km). This is where people usually notice a line most clearly.
150 to 300 miles. Still relevant, especially if the place already matters to you.
300 to 500 miles. More atmospheric than exact, but worth checking for context.
Practical rule of thumb
If a city feels important to you already, check it even if the line is not exact. Context often matters as much as precision.
Planet Themes at a Glance
Think in clusters instead of memorizing thirteen isolated keywords. This gives you a faster first read before you drill into each specific line.
Visibility & momentum
Sun: identity, confidence, purpose
Mars: drive, pressure, assertion
Jupiter: growth, opportunity, expansion
Saturn: structure, duty, long-term effort
Belonging & connection
Moon: comfort, emotion, attachment
Venus: love, ease, beauty, sociability
Mercury: movement, learning, conversation
Neptune: inspiration, sensitivity, idealization
Change & deeper growth
Uranus: disruption, freedom, reinvention
Pluto: intensity, power, transformation
Chiron: healing, teaching, tender growth
Nodes: familiar patterns versus future direction
Why Nearby Cities Matter
The city list is one of the most useful parts of the tool because it turns abstract line geometry into places you can recognize, compare, and investigate further.
Use cities as anchors
Click a suggested city to jump straight to that area of the map and inspect the lines around it.
Check recognition first
Start with places you already know, then expand to places you are seriously considering for travel or relocation.

How to Use Your Astrocartography Map
Use the tool like a decision aid, not a wallpaper generator. These four steps will give you a clearer read than skimming the whole globe at once.
Step 1
Compare places you already know
Start with cities where you have lived, studied, worked, or fallen in love. The map makes more sense when you test it against experience first.
Step 2
Match places to the life theme you want
Career searches might start with Sun, Jupiter, or Saturn lines. Relationship questions often turn attention toward Venus, Moon, or Descendant lines.
Step 3
Inspect exact locations, not just countries
A line rarely describes an entire nation equally. Click the map, inspect the nearest lines, and compare nearby cities before making assumptions.
Step 4
Use astrology with practical filters
Astrocartography is best as a narrowing tool. Pair it with cost of living, language, visa realities, climate, and your actual support system.
One important limitation
Astrocartography depends on the same birth details you would use for a birth chart. Even a small birth-time error can shift angles enough to change how a city reads, so use the most accurate time you can.
Best when you are asking:
Where might career visibility come more naturally?
Which places feel easier for relationships or home life?
Why did a specific city affect me so strongly?

Frequently Asked Questions
What is an astrocartography chart?
An astrocartography chart maps where each planet in your birth chart was angular — rising, setting, at its highest or lowest point — at the moment you were born. The result is a world map of planetary lines showing where different energies are strongest for you. The technique was developed by astrologer Jim Lewis in 1976.
How do I find my astrocartography?
Enter your birth date, exact birth time, and birth location in the form above to generate your personal astrocartography map. Your birth time must be accurate — even small differences shift the planetary lines significantly.
Do I need my exact birth time for astrocartography?
Yes, birth time is required. Astrocartography is based on where planets were angular at your birth, and angles shift significantly with even small time differences. Without an accurate birth time, the lines on your map would be unreliable. Check your birth certificate or hospital records for your exact time.
Is this astrocartography calculator really free? Do I need to sign up or enter my email?
Completely free — no account, no sign-up, no email required. Your birth data is used only to compute your chart and is not stored. You can generate as many charts as you want.
What do the different astrocartography lines mean?
There are four line types: MC (Midheaven) lines relate to career and public life. IC (Imum Coeli) lines relate to home, family, and roots. ASC (Ascendant) lines influence how you present yourself and are perceived. DSC (Descendant) lines highlight partnerships and relationships. Each planet adds its own theme — for example, Venus DSC suggests a place favorable for romantic connections.
How do I use my astrocartography map?
Look at which planetary lines pass near places you've lived, traveled to, or are considering. Check the line type and planet to understand what themes that location activates for you. Pay attention to where lines cross — these intersections combine the energies of both planets. The closer you are to a line, the stronger its influence.
How accurate is this astrocartography map generator?
This calculator uses NASA JPL ephemeris data for planetary positions, providing high-precision astronomical calculations. The planetary line positions are accurate to within a few miles. The same ephemeris data is used by professional astrology software.
Should I move based on my astrocartography chart?
Astrocartography is one factor among many in location decisions. It highlights potential energies, not guarantees. Practical considerations — cost of living, career opportunities, language, climate, and personal circumstances — matter as much or more than planetary lines. Use your chart as one input alongside real-world research.
What are the best astrocartography lines for love, career, or creativity?
For relationships, look for Venus DSC (partnerships) or Venus ASC (attractiveness) lines. For career, Sun MC or Jupiter MC lines emphasize professional visibility and opportunity. For creativity, Venus MC or Neptune ASC lines can enhance artistic expression. Remember that every planet brings both opportunities and challenges.
How far from a line do I need to be for it to affect me?
Most astrologers consider the influence strongest within about 150 miles (240 km) of a line. Between 150-300 miles, the influence is moderate. Beyond 300 miles, it fades significantly. The exact distance varies by practitioner, but 150 miles is the most commonly cited threshold.
