Scrub the date and a second, dated set of lines sweeps the map: transits, progressions, solar arc, returns. A place quiet today can carry a Jupiter line next spring.
Every time overlay
Solar-eclipse paths and magnitude contours drawn across the map, with each eclipse’s contacts to your natal chart worked out for you.
How eclipses are drawn
Move your pointer and the chart recasts under it: new angles, new houses, the wheel turning as you go. Double-click to pin a place, or search a city and fly there.
Everything the map does
Local Space draws one direction line per planet from any pin you drop. The question is which way, not how far.
Every kind of line
Drag the world under your fixed natal lines and watch the sky turn, hour by hour. Parans stop being an abstraction once you see one planet reach the Midheaven exactly as another rises.
Parans, Slide and Sky Times
Lay a second person’s chart over yours, and “where should I move?” becomes “where should we move?”
Charts, synastry and composites
Star lines for Regulus, Spica, Algol and company, about forty more minor bodies, and every rise, culmination and set for the place you are reading.
The full list of bodies
Earth’s warm atlas is everyone’s. A free account adds Glass’s frosted silver over a bright map, Dark for late nights, and Plain, the quietest: a grey map, solid panels and heavier lines. A theme changes how the app looks, never what it calculates.
The four themes
Set the line system to Geodetic and 0° Aries sits at Greenwich: every place takes its Midheaven and Ascendant from its coordinates, and your lines fall by zodiacal degree. The geodetic map is everyone’s. A free account shades its zones by element and modality, and adds event charts for moments in the world, from an ingress to a founding.
Geodetic maps and their zones
Designed for astrocartographers.
Pro is the toolkit for people who read places for clients: ask the map questions, scan a city, date a line, and hand over a report.
Discovery lets you ask the map a question instead of reading it line by line. It ranks the world’s cities by life theme: love, career, prosperity, home, learning, creativity, vitality, adventure, spirit or focus.
Discovery and Radar in full
Sweep a circle over any place and the map dims to reveal every line running near it, nearest first.
A line on the map tells you a place matters. Activations tells you the dates.
Galaxy is the 3D sky around the Earth: the constellations, the Milky Way, and the planets on their orbits above the lines they draw.
Everything in Pro
Notes on each line in the same circle. Written by hand, not generated.
Tag the spots that matter and tie each to a chart.
Compose in AstroLina, finish in your own editor.
Parans tell you where. The Paran Clock tells you when.
On Pro, the fourth theme is yours. Start from a ready-made look, then change what you like: the panels, the map, each planet’s line, one ink for every line, heavier or finer strokes. It saves as you go, follows you to your other devices, and shares with anyone on Pro as a code they paste in.
The theme editor in full
Pro is unlocked from the account screen inside the app. Prices are in US dollars, before tax; outside the US, Pro is billed in Canadian dollars. Checkout is handled by Stripe, and you can cancel at any time.
The engine, the frames and the conventions are written up in full: under the hood.
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 stuff 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.

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.
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.
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.
Yes. The core is free, open-source software (AGPL-3.0), and you can draw your map without creating an account. A free account adds more tools and lets you sync your saved charts across your devices. To see which tools are free and which are Pro, the features page marks every one of them.
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.
Yes. Dark is one of four themes in the Appearance section of Settings: a deep slate map under dark panels, made for late nights. It comes with a free account (Earth is open to everyone). With Pro, the fourth theme becomes your own, from the panel colour down to each planet’s line. See the four themes on the features page.
In six: English, Español, Português (Brasil), Türkçe, Deutsch and Русский. It follows your browser’s language, and you can change it any time in the Appearance section of Settings. Menus, line readings, the help centre and reports are all translated. Where your browser can translate on the device itself, up to two dozen more are offered under Auto-translated. Emails from us are in English. More on what is translated.
Yes. Without an account, your charts are kept only in your browser and never reach us. Two things do go online, as with any map: the map tiles, and a place search when the built-in city atlas doesn’t know the name. With an account, syncing is your choice: when you sign in on a device, the app asks whether to Sync with my account or Keep on this device only, and nothing syncs until you answer. Keep your charts on the device, and nothing you save there leaves that browser. You can change your answer any time on your account screen. We don’t sell personal information or run ads or trackers, and you can delete any chart, or your whole account, whenever you like. The full story is in our privacy policy.
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.
