Introduction
If you have ever opened an AstroCartography map for the first time, you have probably had the same reaction as most folks. It’s very alluring, and you want to know what all the lines mean.
A web of colorful lines swerves around the map-flattened globe. Every line is labeled with a planetary glyph. You point and click, and most websites give you the bubble gum version. Venus means love. Jupiter means luck. Saturn means hardship. Pluto means transformation. Before long you are trying to decide whether you should move to Portugal because a blue line runs through Lisbon.
Nothing against the move-to-Portugal trend, but I do not recommend starting there.
In fact, I think it is bass-ackwards, and doesn’t give the weight of relocation its due.
Over the last ten years, I have completed thousands of AstroCartography readings for clients around the world. I have traveled extensively across North America and Europe, exploring my own lines and relocated charts. I have delivered talks on the subject for the Astrological Society of Kentucky, my home state and where I ended up settling and raising children. I have developed a methodology that goes far beyond what you will find in any free online map, and most any person calling him or herself an AstroCartographer.
If there is one thing I have learned, it is this:
An AstroCartography map does not tell you who you are. It tells you where different parts of who you already are step into greater emphasis, for better or worse./p>
That may sound like a subtle distinction, but it is the difference between treating the map as fortune telling and using it as a tool for understanding the relationship between yourself and place.
This page will teach you how I actually read an AstroCartography map. Not as a collection of planetary keywords, but as a symbolic map of your relationship with the Earth.
The Biggest Mistake Beginners Make
Most people begin by looking for a Venus line. Or a Jupiter line. Or whichever planet they read is supposed to bring wealth, love, or happiness.
I understand why. That is how most introductory articles explain AstroCartography.
The inherent issue being bypassed is that Earth is alive, impeccably layered and complex, and so are you! The window shopping approach is a disservice to your soul, and the ecosystem of meaning (astrology!) that holds and moves you every day.
I work with over 1,300 lines (picture). I look at asteroids, subtle aspects, and various midpoint structures on your map and in your relocated charts. I layer timing on top of location. I spend hours compiling notes on a client’s chart before we ever properly meet. (And it’s always a good time. I genuinely love this stuff.)
Every line exists in relationship to every other line. Each curve on the map belongs to a natal chart. point on the Earth carries an energetic signature specifically for you. We don’t always realize it in the moment, but Place is just as alive as Time, and both are in a constant exchange with your unique physical and spiritual DNA.
Venus on the Midheaven for one person can be wonderfully supportive. For another, it may coincide with relationship dependency, avoidance of necessary conflict, or simply a period where beauty and pleasure become distractions from the work they are here to do (and so, great for a refreshing getaway).
The line did not change. The chart did.
Which means you cannot separate the map from the birth chart that created it.
Your Birth Chart Comes First
This surprises many people.
When clients come to me for an AstroCartography reading, we do not immediately start looking at maps. Instead, I spend blissful hours understanding their natal chart.
What are the dominant themes?
What planetary patterns vibrate throughout the chart?
Which midpoint structures reveal the client’s deepest circuitry?
What planets have the strongest relationships with the angles?
What psychological currents seem to have shaped this person’s life from the beginning?
Only then do we begin asking geographical questions.
Why is that?
Because geography does not replace your chart. It emboldens, diminishes, or aids the flow of different facets of it.
Think of your birth chart as a live orchestra (the Music of the Spheres! What a cool phrase). Your AstroCartography map tells you where different instruments become louder or quieter.
The song remains the same. The arrangement changes.
This is a distinction that most free guides completely miss. They treat the map as a standalone tool, as if moving to a new line will magically transform you. It will not. You will still be you. The question is which parts of you become easier to express.
What an AstroCartography Map Actually Shows
The Four Angles, the Two Axes
The are four angles of your chart, which form two separate axes. Your map contains two primary types of lines: planets in different relationship to each of these axes. These are the foundation of any reading.
The Interpersonal Axis
This axis is created by the Eastern and Western horizons of Earth, where planets rise and set each day.
The Eastern horizon is called the Ascendant, or AC. It represents your relating self. The person people meet when they meet you.
The Western horizon is called the Descendant, or DC. It represents the proverbial Other. This spot in your chart tells me what sorts of people repeatedly walk into your life.
Together, the AC and DC form what I call the Interpersonal Axis. The swerving lines across your map are all a part of this theme, showing us what sort of interpersonal patterns you might expect in a place.
Root and Crown: the Axis of Purpose
This axis is formed by the Zenith and Nadir points in a planet’s daily journey around our Earth.
You have heard of High Noon. That is when, locally, the Sun is at its absolute high position in the arc it travels overhead. This point in the sky exists whether or not the Sun is there, and we astro nerds track it.
Astrologers call it the Midheaven, or MC for short. I call it the Crown. (More on that later.) It tells me about your action in the public realm, and what you’re known for. That is why it’s often tied to the idea of “career”.
High Noon has it’s opposite, which I call the Midnight point. This is when the Sun, or any planet, is at it’s deepest position in its daily journey around the globe.
Astrologers commonly call it the Imum Coeli, or IC for short. I call it the Root. It tells me about themes from your home life that started when you were young, and continue to this day. Elements of your private life are shown here, with echoing stories and patterns passed down from your ancestors.
I always say: like any tree, the Root feeds the Crown. Our purpose is informed by our personal past and our ancestors. The purpose, like the crown of a tree, is visible to all, and what nature lovers use to identify the tree. But without a strong root system, which is just as impressive but burrowed underground and out of sight, the upper part of the tree is not functional.
The Root and the Crown are not separate. They act in concert to craft your story.
The perfectly vertical lines on your map are all acting upon this theme of purpose, showing how that private/public dichotomy plays out in a given place.
The Overlooked Key
Truly understanding these two axes is the keystone to locational astrology. These four angles are the most sensitive and mobile points in the natal chart, changing degrees every four minutes! (Whereas the travels 1 degree per day.)
If you do not put the axes first, you will not be able to differentiate one Saturn or Mars line from another. And such short-sightedness could prove to be a very impactful mistake.
How to Find Your Lines on a Map
That might have gotten a little deep for this 101 Course. So let’s bring it back to basics.
Now that you understand the two axes and their angles, let’s look at a simple map.
Open your AstroCartography map or check the map of Bitcoin above. You will see several lines running across the globe. Each line is labeled with a planetary glyph and an abbreviation or glyph for the angle it is on.
For example:
A diagonal line labeled “Venus AC”, or with the Venus glyph and a simple circle, means Venus was rising at that location at the moment of your birth.
A vertical line labeled “Saturn MC,” or with the Saturn glyph and a simple circle, means Saturn was at High Noon at that location.
A vertical line labeled “Jupiter IC,” or with the Jupiter glyph and two circles connected by a line, means Jupiter was beneath the Earth at that location.
The Orb of Influence
Start With a Place You Know
Understanding Intersections and Parans
When two or more angular (AC, DC, MC, or IC) lines cross in a region, their energies radiate outward from that intersection like light from a bulb. A Venus line and a Saturn line intersecting creates a very different experience than a Venus line alone.
If you have heard of paran lines, this is where they come from.
The theory behind parans is that the combined energy of the two intersecting lines wraps laterally around the globe. So you could be 5,000 miles away from an intersection of a line, but as long as you are on the same latitude as that intersection, its energy is still prominent.
I have serious questions about the validity of this theory, because it is not based on the birth chart at all. Still, it doesn’t hurt to check.
Why Midpoint Lines Matter
A midpoint is the point exact halfway between two planets in your natal chart. Each midpoint occupies a degree in the zodiac (like, 7 degrees Cancer).
So if that degree is rising, setting, on the crown or on the root in a place, you would see a midpoint line, where those two planets’ energies synthesize in a specific way.
Some of the most significant placements for my clients have been midpoint structures that did not show up on their free maps at all.
For example, I had a client whose Mars-Jupiter midpoint pattern was prominent on the Midheaven in Ecuador. This engendered a very particular pattern for her life there as a postgraduate. She was very intent on achieving as much as she could, on a very big scale. Even the little things, she did in a big way. It was a huge influence on her time there, and it fed into her next moves in life as well.
Midpoints are so rich in meaning. One midpoint line I always look out for is Saturn-Pluto. This line is a huge red flag for a place, unless you are looking for the austere, dutiful, isolated struggle of the Saturn-Pluto experience. This combination of intense gravity with duty-bound entanglement is very difficult to escape from.
A Real-World Example: Reading a Client's Map
I would encourage you to check out my sample video of an AstroCartography reading for two places, But to stay with me here, et me walk you through a real, anonymized client example.
The Client's Background
A client came to me feeling unsettled. She had lived in Chicago for over 20 years but had never felt truly grounded. She described her experience as “like quicksand or a vacuum that pulls you or sucks you back in.”
She had visited other places and always felt more alive. She had tried to move to Milwaukee once, but it fell apart unexpectedly. She thought maybe she was just restless.
The Birth Chart
When I looked at her natal chart, one thing was immediately clear: Uranus was a predominant planet. It was not just present in Chicago; it was a central piece in her chart.
Uranus is the planet of the present moment, freedom, spontaneity, newness, and emergence. It is associated with unpredictability, innovation, and sudden change. When it is prominent, and exciting life is guaranteed, but stability and long-term commitments and achievements are rare.
The Map
Reframing for Understanding
We discussed what this meant.
Living on her Uranus MC line was not “bad.” It just flowed with a particular lifestyle. Freelance work that allowed for every day to be different. An openness to adapt to unexpected changes. The foresight to hedge against instability by setting money aside during good times.
She realized her restlessness was not a character flaw. It was a predictable result of living on her Uranus line for two decades.
This is what a reading does. It takes the abstract and makes it real and actionable.
Conclusion: What the Map Offers and What It Can't
Learning to read an AstroCartography map is a process. It takes practice, study with time and experience, and a willingness to let the planets speak for themselves.
If you have followed along with this guide, you now know:
- The two axes, their four angles, and what they represent
- >How to find the lines on a map
- Why the birth chart comes first
- How to start with places you already know
- Why all lines matter, not just angular lines
But here is the truth: reading your own map alone is limited.
You can see the lines, but you cannot always see the full pattern. You can recognize a Venus line, but you may not recognize how it interacts with an unseen midpoint structure that completely shifts the character of Venus.
That is where a professional reading with me comes in.
What a Reading with Me Offers
I’ll say it one more time. I work with over 1,300 lines, including asteroids, subtle aspects, and midpoint structures that free maps miss entirely. My software, Sirius, is a significant investment.
I spend hours compiling notes on your chart before we ever speak. I analyze your birth chart in depth to understand the patterns that shape your life. I look at relocated charts, not just the map. I layer timing on top of location.
Most importantly, I do not treat you like a mass-produced product. We establish a relationship and we can keep talking when the first reading is complete. Over the years, clients who want to learn AstroCartography have really cut their teeth from just a few readings with me, and having those recordings to study.
