About Astrocartography
Astrocartography is a small independent product focused on one job: help people turn birth data into a readable astrocartography map that is useful for relocation, travel, work, and relationship decisions.
We publish the product under the names Astrocartography and Astrocartography AI. Questions, corrections, and support requests can be sent to [email protected].
What We Build
- A free astrocartography chart and map generator that works without mandatory signup for the core flow.
- An interpretation layer that helps readers compare cities for relocation, travel, visibility, relationships, and lifestyle decisions.
- A lightweight web experience designed to explain planetary lines clearly instead of hiding the logic behind a black-box widget.
How The Calculator Works
Our current stack is intentionally simple and inspectable:
- Planetary positions are calculated on the server with the local chart engine. The code uses Swiss Ephemeris files when they are available and falls back to Moshier mode when they are not.
- Birth locations are resolved through OpenStreetMap Nominatim when the user does not supply latitude and longitude directly.
- Map rendering uses Leaflet with OpenStreetMap and CARTO tiles so users can inspect line geometry on an interactive world map.
- Core calculation requests are handled server-side instead of embedding a third-party astrocartography widget.
First-Party Research And QA
We do not want "trust us" copy. We keep real internal checks in the repository and use them whenever we adjust line-generation logic.
- We maintain an internal cross-region regression set with 8 cached sample charts covering Beijing, London, Sydney, Tokyo, Rio de Janeiro, Nairobi, Mexico City, and Buenos Aires.
- 1 holdout sample is kept outside the main fitting set so we can catch regressions after model or correction changes.
- The comparison scripts summarize mean and maximum line deltas against cached reference charts. We use that work for QA, not as a public marketing claim of absolute certainty.
Editorial Standards And Boundaries
- We treat astrocartography as decision support, not destiny. A map can highlight patterns and trade-offs, but it should still be weighed alongside visas, safety, cost of living, work reality, family needs, and health constraints.
- We do not frame the site as medical, legal, or financial advice.
- When we make methodological changes, we prefer traceable implementation notes and benchmark checks over vague claims of improvement.
Privacy And Data Handling
The core calculator flow is designed so birth data is used to calculate the map response and is not stored permanently as part of chart generation. That privacy posture matters because birth time and birthplace can be sensitive personal data.
Identity And Contact
Astrocartography is maintained by the Astrocartography editorial team. If you need support, want to report an error, or want to challenge a claim on the site, email [email protected].
