Best Astrocartography Locations Calculator — Rank Places by Your Planetary Lines

What 'best location' means in astrocartography

Every planetary line marks places where that planet was rising, culminating, setting or at the nadir at your birth instant. A city is traditionally 'good for you' when strong lines pass close to it — closer is stronger, and more relevant lines stacked on one place make it stronger still. Ranking is simply that comparison done systematically: for each candidate location, find every line within a radius and score proximity.

This tool does the ranking for a fixed shortlist of well-known cities across every continent, and for any place you search. Because line positions are pure geometry of your birth instant, the whole computation is deterministic astronomy — the interpretation of what a Jupiter-ASC line 'means' is the traditional layer, clearly separated from the measurement.

How we compute the ranking

Your planetary lines are solved exactly for the birth instant: for each of the ten bodies from sub-arcsecond astronomy (VSOP87/ELP via astronomy-engine), the engine finds, at every 4° of latitude, the longitude where that planet sits on the Ascendant, Descendant, MC or IC — the same solver that draws the astrocartography map.

For each candidate place we measure the angular distance to every line and keep those within 6° (about 670 km). A score is then summed: a line passing directly over a city contributes its full weight, one at the radius edge contributes almost none, and the total orders the list. Filters let you restrict to personal planets plus Jupiter/Saturn (the classical 'benefic and malefic' set) or all ten bodies, and to any combination of the four angles.

What you get

After entering your birth data:

• A ranked list of up to 12 strongest cities from a 28-city world shortlist, each with its line hits and distances.
• Per-city line chips: which planet, which angle, how many degrees away.
• Filters for line families (personal+ vs all ten) and angles (ASC/DESC/MC/IC).
• A search box scoring any city or town on Earth with the same math.

How to weigh the hits

Traditionally the angle decides the arena before the planet decides the flavor: ASC lines color who you are and what you start in a place, MC lines its career and visibility, DESC lines its relationships and public contacts, IC lines home and roots. A Sun-MC city is read as 'where you shine at work'; a Venus-DESC as 'where love finds you easily' — house-style formulas, not guarantees.

Then weight by distance and number. A city with three lines within 2° is a far louder candidate under this technique than one with a single grazing Venus line at 5.8°. And the classical caution still applies: the strongest line for relocation is usually the one closest to, but not exactly on, your town — practitioners describe being 'on' a line as living the theme at full volume, which is not always comfortable.

A worked example, with real numbers

Take a chart cast for 5 May 1990, 9:15 a.m. New York local time (13:15 UTC). With all line families switched on, Mumbai tops a typical sample: Mercury-DESC 3.1°, Sun-DESC 3.9° and Pluto-ASC 5.2° — three lines inside the radius. Reykjavik follows with Mercury-MC 4.1°, Sun-MC 4.8° and Pluto-IC 5.8°. The native’s own hometown, New York, scores four hits: Uranus-DESC 1.5°, Neptune-DESC 5.2°, Jupiter-ASC 5.3° and Mars-MC 5.5°.

Tokyo lands mid-table for this chart with Jupiter-DESC 4.4° and Uranus-ASC 5.5°, while Sydney and Lagos have no line within 6° at all — for this birth, the technique simply says nothing about them. Filter to personal planets plus Jupiter/Saturn and the outer-planet hits (Neptune, Uranus, Pluto) disappear and the ranking reshuffles: a built-in demonstration that the list is a model, not a verdict.

What this tool does not claim

There is no controlled evidence that living on a planetary line changes outcomes — the entire astrocartography literature is pre-replication, and relocation studies are anecdotal. The shortlist is also ours: 28 well-known cities, not every town on Earth, so a great unlisted place simply isn't scored (search it instead).

Distances are angular (1° ≈ 111 km) from a latitude grid sampled every 4°, so a hit is accurate to a few tens of kilometers, not to the meter — appropriate for choosing cities, not houses. Birth data never leaves your browser; the ranking is computed locally.

Ranking vs the map vs relocation

The Astrocartography map shows you every line at once — best for seeing the geometry and choosing regions to explore. This tool answers the comparative question: of the places I could realistically live, which does the model prefer? The Relocation chart then takes your winner and re-casts your houses for it — the third step of a standard locational reading. All three share one line solver, so the numbers never disagree.
