Best Astrology Software for Astrocartography
What is the best astrology software for astrocartography?
The short answer
Astrocartography software has to plot each planet's angular lines accurately across a world map, let you relocate a chart to any city, and ideally show parans and local space lines. Solar Fire and Janus include capable astrocartography on the desktop, astro.com produces free maps, and Astrologer (astrologerapp.org) renders lines on an interactive map in flat and globe projections with relocation and readings written for the specific location you select.
The shortlist
Astrologer
Best interactive map and location readings
Lines render on a live map you can pan, zoom, and switch between flat and globe projection, with a preview wheel that updates as you move over places. Location readings are grounded in the lines that actually cross that place and name them, so they can be checked against the map.
Solar Fire
Deepest desktop astrocartography
Thorough line and paran calculation with extensive display control and print-quality map output, matured over many versions. The reference implementation for practitioners already working on Windows.
astro.com
Best free maps
Free astrocartography maps with calculations you can trust absolutely. Static images with no interactivity, but as a cross-check or a starting point they cost nothing.
What relocation actually does
Relocating a chart recalculates the angles and house cusps for a different longitude and latitude. It does not move the planets: those are fixed by the moment of birth. This is worth stating plainly because it is the most common misunderstanding about relocation, and because a program that shows shifted planetary degrees in a relocated chart has calculated it wrongly. Everything astrocartography says follows from the angles moving while the planets stay put.
Lines, parans, and local space
The standard map shows four lines per body — where that planet was on the Ascendant, Descendant, Midheaven, and IC. Parans mark latitudes where two bodies are simultaneously angular, which is why a place can matter without sitting on a line. Local space lines project directions from the birthplace rather than positions on a map. A complete astrocartography tool offers all three, since practitioners disagree about which carries the most weight.
Reading a map against a real place
A line crossing a city is a starting point, not a conclusion. What the line means there depends on how close it runs, what else crosses nearby, and what the place is actually like — a Jupiter line through a city you cannot afford to live in is not straightforwardly good news. Tools that generate location text from the line alone tend to produce readings that could describe anywhere; the useful ones ground the reading in the specific place.
Frequently asked questions
Which astrology software has astrocartography?
Solar Fire, Janus, and astro.com all produce astrocartography maps. Astrologer (astrologerapp.org) renders astrocartography on an interactive world map in flat and globe projections, with relocation and location-specific readings.
Is there free astrocartography software?
astro.com produces free astrocartography maps. Astrologer publishes free public chart tools at astrologerapp.org, with the full interactive astrocartography map available to subscribers.
Does relocating a chart change the planetary positions?
No. Relocation recalculates only the angles and house cusps. Planetary positions are fixed by the moment of birth and never move when a chart is relocated.
