How to read the map

Four angles. Four ways to read a line.

The lines show where a planet meets the horizon or local meridian at the chart’s chosen moment. Astrology attaches symbolic themes to these angles; those meanings are interpretive, not measured effects on your life.

MC · MidheavenMedium Coeli

Career, Reputation & Public Zenith

A planet crosses the upper local meridian. This does not mean it is directly overhead. Traditionally associated with public life, work, and reputation.

IC · NadirImum Coeli

Inner Sanctum, Home & Ancestry

A planet crosses the lower local meridian, opposite its upper transit. Traditionally associated with home, roots, and private life.

AC · AscendantRising Line

Vitality, Persona & Direct Action

Locations where the body meets the eastern horizon. Traditionally associated with identity, self-expression, and beginnings.

DC · DescendantSetting Line

Partnerships, Mirrors & Alliances

Locations where the body meets the western horizon. Traditionally associated with partnership, collaboration, and encounters with others.

How nearby lines are grouped

CLOSE0–150 km

The closest distance group in this page’s model. “Close” describes proximity, not a stronger effect on your life.

NEARBY151–500 km

An intermediate distance group for browsing nearby lines. These cutoffs are interface conventions, not measured influence zones.

REGIONAL501–800 km

The broadest group included in a location reading. Curved-line distances are approximate, based on the sampled map geometry.

Frequently Asked Questions on Astrocartography

A practical guide to the controls, calculated lines, and limits of interpretation.

Q1What does an astrocartography map show?
▼
An astrocartography map shows where celestial bodies meet the horizon or local meridian at a chosen moment. This page combines calculated positions with traditional astrological meanings. Use it to explore a symbolic framework, not to predict events or decide whether a destination will improve your life.
Q2What do MC, IC, AC, and DC mean?
▼
MC marks upper meridian transit, while IC marks lower meridian transit. AC and DC mark rising and setting along the horizon. Astrology traditionally links these angles to public life, home, identity, and relationships respectively. Meridian transit does not necessarily mean a body is directly overhead.
Q3What do the distance groups and scores mean?
▼
The reading groups estimated distances as close (0–150 km), nearby (151–500 km), and regional (501–800 km). These are this interface’s conventions, not measured influence zones. The symbolic index starts at 20 and adds weighted nearby lines, capped at 100. It is not a probability.
Q4What are parans?
▼
Parans describe combinations of planetary angular events associated with a latitude. This page calculates crossings and lists those within 1.8 degrees of the selected latitude. Their astrological descriptions are symbolic interpretations. A listed crossing does not demonstrate that a whole latitude shares the same life experiences.
Q5Should I enter local birth time or UTC?
▼
Enter the date and time in UTC, not unconverted local time. A timezone or daylight-saving difference changes the chart. Use a reliable conversion for the birthplace and historical date. If the time is unknown, explore an example without treating its lines as a precise personal reading.

Sources & interpretation notes

Calculated sky

Astronomy Engine supplies planetary positions. North Node and Chiron use separate approximations. The map is an exploratory visualization, not an observational navigation tool.

Geographic context

Country outlines and names come from Natural Earth through World Atlas. Place labels are a separate Esri layer. Simplified boundaries are not a statement on territorial claims.

Symbolic readings

Themes, descriptive readings, and the 0–100 index are Lunologium’s interpretation layer. They are not findings from the astronomical software or geographic data providers.
