Free Astrocartography Chart Calculator, Lines Explained

An astrocartography chart maps where each planet in your birth chart was angular: rising, setting, at its highest point, or at its lowest point at the moment you were born. The result is a world map of planetary lines showing where different symbolic themes are most emphasized. The technique was developed by astrologer Jim Lewis in 1976.

Enter your birth date, exact birth time, and birth location in the form above to generate your personal astrocartography map. Your birth time must be accurate because even small differences shift the planetary lines significantly.

Yes, birth time is required. Astrocartography is based on where planets were angular at your birth, and angles shift significantly with even small time differences. Without an accurate birth time, the lines on your map would be unreliable. Check your birth certificate or hospital records for your exact time.

There are four line types: MC (Midheaven) lines relate to career and public life. IC (Imum Coeli) lines relate to home, family, and roots. ASC (Ascendant) lines describe how you present yourself and are perceived. DSC (Descendant) lines highlight partnerships and relationships. Each planet adds its own theme. For example, Venus DSC may describe a place where romantic or social themes are easier to notice.

Look at which planetary lines pass near places you've lived, traveled to, or are considering. Check the line type and planet to understand what themes that location may emphasize for you. Pay attention to where lines cross because these intersections combine the symbolism of both planets. The closer you are to a line, the stronger the traditional interpretation.

Augurine uses the JPL DE440s planetary ephemeris via ANISE, the same data backbone NASA uses for mission planning. Planetary line positions match what professional astrology software produces. The practical accuracy ceiling is the birth time and location you enter, because angles and planetary lines shift quickly when the recorded birth data is off.

Astrocartography is one factor among many in location decisions. It highlights potential themes, not guarantees. Practical considerations like cost of living, career opportunities, language, climate, and personal circumstances matter as much or more than planetary lines. Use your chart as one input alongside real-world research.

For relationships, look for Venus DSC (partnerships) or Venus ASC (social ease) lines. For career, Sun MC or Jupiter MC lines are often read for professional visibility and opportunity. For creativity, Venus MC or Neptune ASC lines can describe artistic expression. Remember that every planet brings both opportunities and challenges.

Most astrologers consider the influence strongest within about 150 miles (240 km) of a line. Between 150-300 miles, the influence is moderate. Beyond 300 miles, it fades significantly. The exact distance varies by practitioner, but 150 miles is the most commonly cited threshold.

Parans are latitude crossings where lines from two different planets intersect, meaning both planets are simultaneously angular at that latitude. On the map, they appear as horizontal dashed bands spanning the globe. If you live near a paran latitude, astrologers read the combined symbolism of both planets. For example, a Sun ASC / Moon DSC paran brings identity and partnership themes into the same location layer.

Angular lines act as house cusps projected onto the globe. Your position relative to a line determines which house that planet's symbolism is read through. For example, being east of an MC line places you in the 9th house side (higher learning, travel, publishing themes), while being west puts you in the 10th house side (career, public reputation). This adds nuance beyond simple proximity because two cities equidistant from the same line can feel quite different depending on which side they fall.

Transit overlays show where planets are angular right now (or on any chosen date), highlighting locations with a stronger timing signal in the present moment. Progressed overlays use the day-for-a-year method to show how your personal map has evolved since birth. Where overlay lines cross your natal lines, astrologers read a more active symbolic zone for travel timing or for comparing why a place feels different now than it did years ago.

Your Sun line marks places where you tend to become more visible and more yourself, which is why it is read for confidence and recognition. The angle refines it: on the MC it points to career and public standing, on the ASC to personal presence and health, on the IC to a strong sense of home, and on the DSC to partners who reflect your identity. Every other planet casts its own line with its own tone, so read your Sun line alongside the other lines that pass near the same place rather than on its own.

These four are the lines most people check first. The Sun line is read for visibility and vitality, Venus for ease and pleasant surroundings, Jupiter for growth and opportunity, and Saturn for structure and slow-built achievement. The first three are usually treated as supportive, while Saturn lines are heavier and more demanding, though each one carries both gifts and costs depending on the angle and how close you are. The map on this page draws all thirteen bodies, so you can compare these four against your Moon and outer-planet lines too.

Not on its own. Astrocartography shows where different themes in your chart are emphasized, so it can point you toward places that may support a goal like career visibility or a restful home base. It does not account for cost of living, visas, language, climate, or the people you would be leaving or joining, and those usually weigh more than any single line. Use it to build a shortlist worth researching, then test each place against the practical realities before you decide.
