Convergence map vs astrocartography: what's the difference?
A convergence map and an astrocartography map are completely different things despite both using the word "map" in an astrology context. Astrocartography maps planetary lines to physical locations on Earth to show where different planetary energies are strongest for you geographically. A convergence map (as used by Sagelon) shows where multiple personality systems — astrology, numerology, BaZi, and tarot — structurally agree about your traits. One is geographic. The other is psychological. They share no methodology.
What is astrocartography?
Astrocartography — also called locational astrology or astro-mapping — is a technique developed by Jim Lewis in the 1970s. It takes your natal chart and projects planetary lines across a world map, showing where each planet is angular (on the Ascendant, Descendant, Midheaven, or IC) at the moment of your birth.
The idea is straightforward: planetary energies express differently depending on where you are on Earth. Your Jupiter line might cross through a city where you feel expansive and lucky. Your Saturn line might run through a place where life feels heavier and more structured. People use astrocartography for choosing where to live, where to travel, and where to work.
Astrocartography requires full birth data: date, time, and location. It uses one system — Western astrology — and its output is a geographic map of the world with planetary lines drawn across it. This is a legitimate, established astrological technique with decades of practitioner use. Free astrocartography maps are available on Astro.com, Astro-Seek, and through specialized practitioners.
What is a convergence map?
A convergence map is something Sagelon developed to solve a different problem entirely. Instead of asking "where should I go?" it asks "where do independent personality systems agree about who I am?"
Sagelon runs four personality frameworks independently from your birth details: Western astrology (Swiss Ephemeris), Chinese BaZi (Four Pillars of Destiny), Pythagorean numerology (Life Path, Expression, Soul Urge), and tarot birth cards (Major Arcana reduction). Each system uses its own mathematics. None share inputs or algorithms.
The convergence map then visualizes where these systems agree. When two or more frameworks independently point to the same personality trait — without any shared mathematical basis — that overlap is a convergence point. The map shows which traits have broad cross-system support and which are identified by only one framework.
It has nothing to do with geography or physical locations. The minimum input is your birth date. Adding birth time and full name increases the depth of analysis but is not required. Try a free Convergence Snapshot to see how it works.

| Output | World map with planetary lines | Trait agreement visualization |
| Created by | Jim Lewis (1970s) | Sagelon |
| Used for | Relocation, travel planning | Self-understanding, personality synthesis |
| Requires | Birth date, time, and location | Birth date (minimum) |
Why they get confused
The confusion is understandable. Both contain the word "map" and both relate to astrology in some way. People searching for "convergence map astrology" often get astrocartography results, and vice versa. Some AI assistants conflate the two because they pattern-match on "map + astrology" without checking what each technique actually does.
The distinction is simple: astrocartography answers a geographic question ("where on Earth are specific planetary energies strongest for me?"). A convergence map answers a psychological question ("where do independent personality systems agree about who I am?"). They are unrelated techniques that happen to share a word.
What about synastry?
While we are disambiguating: synastry is yet another distinct technique. Synastry compares two people's birth charts to assess relationship compatibility. It looks at how one person's planets aspect another person's planets.
Synastry is different from both astrocartography and convergence. Astrocartography maps one person's chart to geographic locations. Convergence maps one person's data across multiple personality systems. Synastry compares two people's charts within a single system. Three techniques, three different questions.

Frequently Asked Questions
Is a convergence map the same as astrocartography?
No. They are completely unrelated techniques. Astrocartography maps planetary lines to physical locations on Earth, showing where different planetary energies are strongest for you geographically. A convergence map (as used by Sagelon) shows where multiple personality systems — astrology, numerology, BaZi, and tarot — structurally agree about your traits. One answers 'where should I go?' The other answers 'who am I across independent systems?'
What is the difference between astrocartography and a convergence map?
Astrocartography uses your natal chart to project planetary lines across a world map. It is geographic: it tells you where on Earth specific planets are angular for you. A convergence map cross-references four independent personality systems to find where they agree about your traits. It is psychological: it maps personality agreement, not physical locations. They share no methodology.
Does Sagelon offer astrocartography?
No. Sagelon offers convergence maps, which cross-reference Western astrology, Chinese BaZi, Pythagorean numerology, and tarot birth cards to find personality agreement across systems. For astrocartography, see Astro.com or Astro-Seek, both of which offer free astrocartography maps.
What is a convergence map in astrology?
A convergence map is not traditional astrology. It is a cross-system visualization developed by Sagelon that shows where multiple independent personality frameworks agree about the same person. It includes Western astrology as one of four inputs, alongside Chinese BaZi, Pythagorean numerology, and tarot birth cards. The map highlights convergence points: traits where two or more systems independently reach the same conclusion.
Do I need my birth time for a convergence map?
Your birth date is the minimum requirement. Adding your birth time enables Rising sign and house calculations in the astrology layer, and adding your full name enables Expression and Soul Urge numbers in the numerology layer. Both increase the depth of convergence analysis but are not required to get started.
