Local Space Maps

Another element of astrocartography, the mapping part of relocation astrology is the local space map. We’ll be looking at more traditional Astro Maps in the coming weeks and months, but the local space map is certainly different, even though it uses the same geography.

This is the local space map of a client I worked with several months ago.

A local space map for someone born in Detroit, MI

This person was born in Detroit, MI and has lived in multiple locations in her life, including Los Angeles and Pittsburgh.

What do these somewhat curved lines mean?

You can see the glyphs of planets on the red lines as well as yellow lines denoted by numbers. The yellow lines are where the house cusps exist. This might be hard to wrap your head around, since we don’t think of house cusps as depending on geographic proximity like that. Or at least, not intuitively.

You can see the yellow line labeled “1” heading almost directly to the east, although it starts to dip south the further east you go. That’s the cusp of the first house — the ascendant. The ascendant is where planets rise and is always somewhere on the eastern horizon, even though it is not usually directly east. So it makes sense — the sun, if it were rising, would be near that line. (It isn’t, as we’ll get into in a bit).

That line cuts directly through Detroit, as all the lines do, and shoots left, west to southwest, ending in number 7 — the cusp of the 7th house. That’s the descendant line — where planets would be setting.

You can see the sun going in two directions — between the numbers “8” and “9” and between the “2” and “3”. All planetary lines go in both directions in between opposite house numbers. Let’s say your Sun is 30 degrees above the horizon and directly southeast. The Sun line goes from where you are, directly at the zenith of the sky, directly toward where the Sun happens to be, southeast.

The line continues, wrapping all the way around the sky — basically what is known as a “great circle” from your vantage point. All lines southeast from the top of the sky to the Sun, then continuing to the horizon, going below the horizon until they are directly under your feet, than wrapping back to the horizon and going up the sky to the zenith, this time directly northwest, on the other side.

All local space lines wrap 360 degrees across the earth like that, depending on where they happen to be in the sky or underneath the earth.

In the northern hemisphere, the majority of the time (although not nearly all the time) planets are south of your vantage point if they’re in the sky (maybe southeast or west, but still south), and north of your vantage point if they’re underneath the earth. At 40 degrees north, if I had to guess an actual figure, each planet has a 70-80 percent chance of ending up this way.

Local space lines can be very powerful. From where I was born to where I live now, I am pretty much directly on my Sun line. That lends itself, according to one source, to creative purpose, vitality, fame, popularity.

According to the same source, the other lines are as follows:

  • Moon – emotional sensitivity, rootedness, hearth and home, family themes
  • Mercury – ideas and information, ideal for education, networking, business
  • Venus – concern with recreation, beauty, and the arts, an enhanced enjoyment of life, possibility of earning more money, attraction of relationships and the feminine, possible vanity
  • Mars – energized, motivated, passionate, driven, defensive, territorial, battleground, conflict
  • Jupiter – embodying the teacher, inspired optimism, synchronistic flow, opportunity, expansion, overindulgence, exaggeration
  • Saturn – hard work, discipline, maturity, seriousness, professionalism, responsibility, pressure
  • Uranus – desire for freedom, rebellious, inventive, original, unexpected surprises, sudden changes, themes around technology
  • Neptune – dreamy, poetic, mystical, contemplative, myth and story, the imagination and arts, confusion, deception, depression, idealism, disappointment
  • Pluto – intensity, drama, empowerment and power struggles, control issues, resistance and release, shamanic work, the unconsious, shadow emotions, hidden agendas in self and other
  • Chiron – recognition of woundedness, stories of victimization, opportunities to heal, mentors, coaches, guidance
  • Juno – issues of fairness and equality, soul-contracts, balance in relationship, marriage partner


This is just one interpretation, but it indicates the strengths that will occur if you live on one of these lines.

In the above graphic you can see this client’s Sun line heading northeast through Ontario, Canada, and also southwest going right through Indianapolis and through eastern Illinois, Missouri, and Arkansas and getting very close to Houston and Corpus Christi, TX. Living on this Sun line allows the person to strengthen their very essence and their vitality.

This client lived in Los Angeles near her Ceres line. Ceres is not in the above list I posted, but according to David Cochrane, Ceres can indicate:

“attempts to bring a healthy, humanitarian way of life to our complex biological and social situation… Ceres brings a desire to bring decency, honesty, support, and a reasonable philosophical perspective to our lives and especially to the difficulties we face.

“Ceres does not simply want to nurture and feed. Ceres acknowledges complex realities and seeks healthy, honest, mature. Ceres provides ideas that are more realistic and pragmatic rather than idealistic.”

Try to contemplate how this might manifest in the location. She was about 50 miles south of her Ceres line, so it wasn’t the strongest of influences.

More interestingly, the client has Jupiter conjunct Saturn to within less than a degree orb (very strong!) and the lines, right next to each other, go right through Pittsburgh. We see the Jupiter and Saturn influence as combining seemly contradictory impulses that translate to a desire for controlled growth. Jupiter wants to make everything bigger but Saturn (in its effort to focus on what’s real and important and lasting, without all the frills) asks, “what are we growing for? What’s important here? What’s going to last beyond our lifetime?”

I can definitely see the client as making the right choice by moving to Pittsburgh, and creating something large and of lasting value. It isn’t the only reason I recommended the location for her (and we haven’t even gotten into the backstory), but it is a major reason.

Local space maps tell us a lot as one element of a larger survey of both a more normal Astro Map, and are available in many astrological charting programs.
