Astrocartography, for curious minds

AstroLina

A modern open-source mapping tool.

Our Story

Made together, by an astrologer and her son.

My mom, Lina, has spent years deep inside astrology—blending psychological, evolutionary, and traditional principles into something she’d be the first to say she’s still figuring out. “Who makes this shit up?” she’d laugh, mid-analysis, because every day brought something new. I grew up around that language, and eventually it pulled me in too.

When I watched her bump up against the limits of existing astrocartography tools, I built her one. She brought the astrology, I brought the engineering, and somewhere in between, AstroLina took shape. We launched it on the birthday of Jim Lewis, the astrologer who popularized modern astrocartography—it felt right to honor the field he defined.

What started as a gift for her now belongs to everyone.

See the world through your chart.

Three fields: when you were born, and where. The world fills with lines — four main ones for every body — drawn where it stood on one of your chart’s main angles: rising, setting, culminating, underfoot. Live near one and that planet on that angle moves to the foreground.

Start flat, spin it, or both: the same chart and the same lines on a classic Web-Mercator map or a rotatable globe, one keystroke apart. Install it and it keeps drawing with no connection at all; the ephemeris travels with you.

Move your pointer and the chart recasts under it, live: new angles, new houses, the wheel turning as you go. Double-click to pin a place, or search a city and fly there. It is the question astrocartography exists to answer: what would this place make of you?

Latitudes where two planets reach an angle at the same moment. At that latitude their themes stay braided all the way around the world. Fixed stars get their own angle lines: Regulus, Spica, Algol and company.

Drag the world under your fixed natal lines and watch the sky turn, hour by hour or by single degrees, or jump to the next rise, culmination or set. Parans stop being an abstraction once you see one planet reach the Midheaven exactly as another rises.

Solar-eclipse paths and magnitude contours drawn across the map, plus where each lunar eclipse is visible, with type, magnitude, Saros series and duration alongside. Its contacts to your natal chart are worked out for you, and the eclipse moment can join your wheel as a second ring.

One direction line per body, radiating from any pin you drop, your birthplace or your saved home, each running out along that planet’s compass bearing and carrying on as a great circle. Your local-space compass: the question is which way, not how far.

Lay a second person’s chart over yours and “where should I move?” becomes “where should we move?” Both line-sets on one map, with a bi-wheel and cross-aspects. Or derive the couple’s own composite and Davison charts and map those instead.

Scrub the date and watch a second, dated set of lines sweep the map: Jim Lewis’s cyclocartography, solar arc, primary directions, secondary and tertiary progressions, solar and lunar returns, plain transits. A place quiet today can carry a Jupiter line next spring.

Frame the map at 1:1, 4:5 or 16:9, compose inside it, then download or copy the PNG. The caption names the chart, and its place follows your pin. Or copy a link instead, and whoever opens it lands on this chart, camera and pin.

When reading places becomes your work.

Launch map View all features Built on a free, open-source core — that’s everything under “For Everyone”. The Pro add-ons here are proprietary.

Your chart in 3D: the lines draped on a turning Earth, and above it the planets that cast them, each on a plumb line down to its zenith point. The ecliptic and horizon rings, named stars and constellations, and a time bar to play the sky forward.

Ask the map a question instead of reading it line by line. Rank the world’s cities against a life theme, or run it backwards: name a line or a paran band and get the cities near it. With a composite chart active, it reads for two.

Sweep a circle over any place and the map dims to reveal every line running near it, even the families you’ve switched off. Nearest first, with the distance to each, and the local-space bearings that point toward the spot. Every place box here resolves a street address.

The same circle, read as prose. A lead line for the strongest influence, then every line, paran and star contact in range, grouped by class and ordered by closeness. Written by hand, not generated, and every section can drop straight into a report.

A pair of rotatable globes in the expanded wheel, natal beside relocated, placing each body by compass bearing and altitude. A Compare table then marks every azimuth aspect retained, changed, lost or new, so you can watch a new horizon rearrange the same sky.

Parans tell you where; this tells you when. A 24-hour track of every angle crossing at the place you’re reading, with the moments two bodies go angular together ringed, and a speculum table listing the day’s exact times. Hover along the track to read any moment.

The “when exactly?” companion. Dated lists of every moment the running overlay stands on one of your chart’s main angles, relocated to the place you’re reading, whether it is transiting, progressed or directed. A line on the map tells you a place matters; this tells you the dates.

Tag the spots that matter and tie each to a chart: the trip that changed everything, the café on your Venus line. Save a pin and it stays on the map flying its country’s flag, synced across your devices and following the chart, not the account.

One switch in Capture and the basemap drops away: the line arrows go, the badges hug the frame edges, and the local-space compass is left alone on a transparent PNG. Lay it straight over a floor plan, a site map, or a backdrop of your own.

Compose in AstroLina, finish in your own editor. Blocks hold wheels, line notes, compasses and parans, each tied to its own place, so one package can walk several cities — then export a real Word file, fully editable: your notes, your letterhead, your compass over a floor plan.

Questions

Curious? So were we.

New to all of this? Start with our beginner’s guide to astrocartography. Already know your way around a chart? The features page documents every tool in the app, one by one.

What is astrocartography?

Astrocartography lays your birth chart over a map of the world. Each planet draws lines through the places where it sat on one of the chart’s main angles — rising, setting, culminating at its highest point that day, or anti-culminating at its lowest — at the moment you were born, and astrologers read those lines as the places where that planet’s themes come forward. If you’d like the full story, we wrote a beginner’s guide to astrocartography.

What do I need to make my map?

Three things: your birth date, your birth time, and your birthplace. The time matters most — the angles that draw your lines shift about one degree every four minutes, so even a rounded-off time can nudge a line by a lot. If you’re not sure of yours, check your full birth records — and if the time can’t be found, an astrologer can help with chart rectification.

How do I read the map?

Start with the lines that pass near places you’ve lived, loved, or keep dreaming about. Each line is labelled with its planet and angle — Venus rising, Saturn culminating — and that pairing colours life in that region: strongest near the line, fading with distance. The guide walks through what every planet and angle means.

Is AstroLina free?

Yes. The core is free, open-source software (AGPL-3.0), and you can draw your map without creating an account. A free account unlocks the Advanced toolkit and syncs the charts you save across your devices. Everything in the “For Everyone” section above is free for everyone — and on the features page every tool carries a badge for the tier it needs, so you can see exactly where the lines fall.

Do I need Pro?

Pro is the toolkit for people who read places professionally: Discovery, Radar, the Report composer, a locational Journal, the 3D Galaxy view, the Local Space dials, the Paran Clock, and more. It’s a paid upgrade — a subscription or a one-time lifetime purchase, whichever suits — unlocked from your account screen in the app. The features page walks through every one of them in detail.

Is my birth data private?

Yes — privacy is the default. We don’t sell personal information or run ad tracking, and when you’re not signed in, your birth details and charts never leave your browser (only place lookups and map tiles touch the network, like any online map). With an account, saved charts sync across your devices — you can delete them or your whole account at any time, or turn syncing off in your account settings, trading cross-device sync for fully local storage. The full story is in our privacy policy.

Do I need to know astrology to use it?

No — curiosity is enough. The map is interactive, every line is labelled, and our beginner’s guide covers the basics in plain language. If you do read charts professionally, Pro is built for you.
