Astrocartography is a fascinating branch of astrology that can help you understand your connection to different places in the world. It was developed by astrologer Jim Lewis in the 1970s.
The basic idea is that when you were born, the planets were in specific positions in the sky. Astrocartography takes your birth chart and projects it onto a map of the world. This creates a series of lines, each representing a different planet's influence.
Your birth chart is a snapshot of the sky from one location at one instant. Astrocartography asks a different question: at that same instant, where else on Earth would a given planet have been rising, setting, culminating or at its lowest point?
Answering that for every planet and all four positions produces the lines you see. Each one traces the set of locations where that planet was angular — that is, at one of the four most powerful positions in the sky — at the moment you were born. Nothing about the sky changes from place to place; what changes is your vantage point on it.
This is why you get four lines per planet rather than one, and why they can appear on opposite sides of the globe. Midheaven and Imum Coeli lines run straight up and down the map, because culmination depends only on longitude. Ascendant and Descendant lines curve, because rising and setting depend on latitude too.
Each line on your map corresponds to a planet (Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto) and an angle (Ascendant, Descendant, Midheaven, Imum Coeli). For example, you might have a "Venus AC" line or a "Jupiter MC" line.
Living on or near one of these lines can amplify that planet's energy in your life. For example:
This is the single most important practical point for a beginner, and the one most often skipped.
The Earth turns 15 degrees of longitude every hour. Because the angles depend on exactly where the sky sat relative to your horizon at birth, an error in your birth time shifts your lines by the same proportion. Four minutes of error moves your Midheaven and Imum Coeli lines by roughly one degree of longitude — about 69 miles, or 111 kilometres, at the equator. An hour of error moves them by around 1,000 miles.
The practical implications are worth stating plainly. A birth time recorded to the minute gives a map you can trust for choosing a city. A time rounded to the nearest hour gives you a map useful for regions, not cities. A guessed time — "sometime in the morning" — makes the AC, DC, MC and IC lines effectively meaningless, though the general planetary positions still hold.
If you have a birth certificate with a recorded time, use it. If you do not, treat your map as indicative and weight your own experience of places more heavily than the lines.

Astrocartography was developed in the late 1970s by American astrologer Jim Lewis. Lewis was a pioneer in the field of locational astrology, and he spent years developing a system that was both accurate and easy to use. He was a brilliant astrologer and a gifted teacher, and he dedicated his life to sharing the wisdom of astrocartography with the world. Thanks to his work, millions of people have been able to use this powerful tool to transform their lives.
Astrocartography is based on the idea that the planets and their energies have a tangible effect on our lives. While this may sound like science fiction, it's actually based on the ancient principles of astrology, which have been practiced for thousands of years. The basic idea is that at the moment of your birth, the planets were in a specific alignment in the sky. This alignment creates a unique energetic blueprint, which is reflected in your birth chart. Astrocartography takes this blueprint and projects it onto a map of the world, showing you where the different planetary energies are most potent for you.
Astrocartography is more than just a tool for finding the best places to live and travel. It's a tool for personal growth and self-discovery. By understanding your astrocartography map, you can gain a deeper understanding of yourself, your strengths, and your challenges. You can learn to work with the planetary energies to create a life that is more aligned with your soul's purpose. Whether you're looking to make a big life change or simply to gain a new perspective, astrocartography can be a powerful guide on your journey.
A map is a lens, not a verdict. It does not account for visas, cost of living, language, climate, work, or the people you would be leaving behind, and no line overrides those. Practitioners who use it well treat it as one input among several — a way of asking better questions about a place rather than a way of settling them.
For the angular lines, yes. Four minutes of error shifts them about 69 miles; an hour shifts them roughly 1,000. Without a reliable time, read the map by region rather than by city.
That is common. Most of the Earth's surface is not on a line, and the orb still leaves large areas uncovered.
They are related but distinct. Astrocartography maps where planets were angular; a relocation chart recasts your entire birth chart for a specific city, including the houses.
Whichever answers the question you actually have. Career points to the Midheaven, relationships to the Descendant, home to the Imum Coeli, and identity to the Ascendant.
