How to read an astrocartography map

Start from places, not lines

Make a short list of the places you could actually live, work or spend a long stretch in, then look at what runs near them. Starting from the lines sends you towards the Kazakh steppe because Jupiter crosses it, and that tells you nothing useful. Three to five real options are enough. Places you've already lived belong on the list too, because they are the best evidence you have.

Read the planet, then the angle

Each line belongs to one planet on one angle. The planet says what comes up there, the angle says where in life it shows:

MC, the Midheaven

work, reputation and what you are known for

IC, the Imum Coeli

home, family, roots and the private life

ASC, the Ascendant

you: your body, energy and how strangers take you

DSC, the Descendant

other people: partners, close friends, clients and rivals

So a Venus line on the MC is liked at work, on the IC a home you love, rising your own looks and manner, setting the people you pair up with. Each planet has a page: Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto.

Judge the distance

A line is a band, not a wall. Zenith Map's scores count a line in full on it, about 60% at 250 km, about 14% at 500 km and not at all beyond 1,000 km. Astrocartographers draw the edge in different places; the methodology page gives the reasoning for this one.

Before trusting any distance, check the birth time. Every four minutes of error moves every line a degree of longitude, so a line 150 km from a city on a time rounded to the quarter hour may run straight through it, or 300 km away. The birth-time guide has the numbers, and what still holds when the time is lost.

Look at what else runs nearby

A place is rarely under one line. A Jupiter line with a Saturn line 200 km away reads as growth that has to be earned, not as luck, and two lines crossing near a city count for more than either on its own. Read the strongest two or three together rather than picking the one you like.

Then look at latitude. Where two planets are on angles at the same latitude, a paran, the pair is read along the whole of it, so a city far from any drawn line can still sit under a pair. The crossings and parans pages give each pair's reading.

Read the planet in your natal chart

A line makes its planet louder; it doesn't change what the planet is like in your chart. A Venus square Saturn at birth brings that square to the Venus line, and a well placed Saturn can make its line one of the most productive places on your map. Check each planet's sign, house and hard aspects before reading its line as good or bad.

Check it against your own life

You already have data. Look up the lines near the places you've lived and ask whether they fit what those years were like: the job that took off, the flat you never settled in, the city where you met someone. If the map describes your past badly, trust it less for your future. Zenith Map's fit check puts up to five places you've lived beside what the engine says about them, though five places are an anecdote, not a test.

Test it with a visit

The habit of the trade is to spend a couple of weeks on a line before signing a lease. Go in an ordinary month, work a few days rather than holidaying, and notice how you sleep and who you meet. A line that feels wrong on a fortnight's visit rarely improves with a mortgage.

What the map can't tell you

Astrocartography says nothing about rent, visas, winters, the language or whether there's work in your field. With Pro, Zenith Map leaves climates and languages you won't live with out of its power cities, and those practical facts should settle more decisions than any line. Read the map for reflection, alongside everything else, not instead of it.
