Astrocartography projects your birth chart onto a world map. Cities near a planet line carry that planet's signature at higher volume — love where Venus rules, drive where Mars rules, home where the Moon rules. The technique Jim Lewis invented in 1976, decoded one line at a time.
Each planet projects four lines through the world — one for each chart angle (MC, IC, AC, DC). Cities within 75 miles of a line live inside that planet's atmosphere. Start with the planet whose theme you're tracking — career, love, home, transformation — or read all ten in order.
Three articles for context: what astrocartography is, how to read your map, and the man who built the system in 1976.
The complete overview. What the lines actually mean, how the technique works, and why your geography shapes which version of you the world meets.
Step-by-step. Orb of influence, line-to-life-chapter matching, what to check first, and the four-step method for reading any planet line.
The astrologer who invented astrocartography in 1976 San Francisco. How ASTRO*CARTO*GRAPHY became the foundation of every relocation reading since.
Once you have your map, the questions get specific. Career? Love? Which angle matters most? How accurate is the technique, really?
Sun MC, Jupiter MC, Saturn MC, and Mars MC each launch different versions of a career. Which one fits your chapter, your craft, your readiness for visibility.
Venus DC for partnership. Moon DC for chosen family. The crossing cities where love is genuinely supported. And the cities to avoid when your chapter is healing.
Every planet draws four lines, one per angle. Understanding what each angle activates is the difference between reading the map and just looking at it.
Cities where two planet lines intersect within 75 miles produce compound effects. Venus-Jupiter, Sun-Saturn, Mars-Pluto — the rare configurations that change the whole reading.

What the research actually shows. Where the technique is most reliable, where it overreaches, and how to evaluate any astrocartography reading honestly.
