Official User Manual & Calculation Architecture
MAREA ASTROLABE
The World's First 3D Interactive Astrolabe & Ephemeris Simulator for Classical & Traditional Astrology.
Bridging NASA JPL High-Precision Celestial Mathematics with Ptolemaic Essential Dignities.
▲ MAREA Main Workspace: Synchronized 3D Celestial Sphere & 2D Classical Astrolabe
Part 1: Philosophy & Scientific Foundation (Lore & Mathematics)
MAREA is derived from the Latin word for "Tide". In classical Mediterranean and Hellenistic traditions, scholars observed celestial bodies not merely as abstract glyphs on paper, but as physical spheres rotating across the local horizon whose gravitational forces physically pulled ocean tides.
🔒 100% Zero-Cloud Local Privacy
MAREA is engineered with a strict local-first architecture. All birth dates, geographic coordinates, and client notes are processed entirely inside your browser memory. Zero chart data is ever transmitted to or stored on external servers.
🌌 NASA JPL High-Precision Ephemeris
Planetary coordinates are computed using the NASA Jet Propulsion Laboratory (JPL) VSOP87 planetary theory and the ELP2000-82 lunar theory, delivering sub-arcminute geometric accuracy.

💬 Client: "I feel uncomfortable putting myself out in front of large audiences."
🌟 Consultant: "Look at the 3D celestial sphere directly above your head (Zenith). At the summer solstice noon when you were born, the Sun and Venus illuminated the highest point of the meridian (altitude +78°). This geometry endows your work with natural public visibility and social recognition. Stepping into the spotlight is where your potential truly flourishes."
🌅 Case 2: Descendant (DSC) Sunset & Collaborative Partnerships
"Completing the self through dialogue, contracts, and strategic alliance"
【Client Theme】
"A solo founder experiences burnout attempting to manage every task alone, yet fears relying on business partners."

- 3D Sphere Visual: The Sun visibly rests right on the western horizon ring, capturing the twilight threshold.
💬 Client: "I tend to believe doing everything myself is faster and safer."
🌟 Consultant: "Look at the western horizon line where the Sun is setting. In classical astrology, the 7th House and DSC represent the gateway to others. Having the Sun at this exact threshold indicates that your greatest achievements come not in isolation, but through strategic partnerships where trusted allies mirror and multiply your strengths."

Part 6: Frequently Asked Questions (FAQ)
🧭 1. General Operation & Basic Usage
Q
How should I configure a chart if the client's birth time is unknown?
Click the "Unknown Time" button in the Consultation Deck. The engine automatically locks the time to 12:00 (Noon) assumption. You can interpret planetary sign positions, essential dignities, and major geometric aspects without time-dependent house cusps.
Q
Can I calculate charts for international locations outside major cities?
Yes. Click the gear icon in the location selector to manually enter any worldwide latitude, longitude (with 0.0001° accuracy), and UTC timezone offset.
Q
How do the 2D Wheel Chart and 3D Celestial Sphere synchronize?
Clicking any planet icon (☉ ☽ ☿ ♀ ♂ ♃ ♄) opens the Planet Inspector and instantly illuminates a glowing beacon ring and radial guide beam from the Earth center to the target celestial body in the 3D sphere.
📜 2. Classical Astrological Engine & Mathematical Logic
Q
What is the difference between Whole Sign and Regiomontanus house systems?
Whole Sign assigns each entire 30° zodiac sign to a house, starting with the Ascendant sign (standard in Hellenistic tradition). Regiomontanus divides the celestial equator into equal arcs and projects them onto the ecliptic (the standard classical quadrant system favored in Horary and Renaissance astrology).
Q
How is Sect (Diurnal vs Nocturnal) computed?
The engine computes the Sun's true geometric altitude relative to the local horizon plane. If altitude is ≥ 0°, the chart is Diurnal (Day Chart); if < 0°, it is Nocturnal (Night Chart). Part of Fortune (POF) automatically adjusts its formula accordingly.
Q
What criteria determine Ptolemaic Essential Dignities?
The 7 traditional planets are evaluated against Domicile (+5), Exaltation (+4), Detriment (-5), Fall (-4), and Peregrine (0) according to standard Ptolemaic and Dorothean tables.
🌊 3. Physical Tidal Forces & Gravitational Biorhythm
Q
What does the 24-hour Tidal Waveform represent?
It plots the combined gravitational tidal potential exerted by the Sun and Moon on the observer's geographic coordinates over a 24-hour cycle. When the Sun and Moon align (New/Full Moon), it produces a Spring Tide (大潮); at quadrature (Quarter Moons), it produces a Neap Tide (小潮).
✦ 4. Pro Edition, Commercial Rights & Local Privacy
Q
Can I sell or distribute the exported consultation sheets to paying clients?
Yes. Pro license holders have full commercial licensing rights to generate, brand, print, and distribute high-resolution consultation sheets in private consultations, seminars, and publications with zero MAREA branding.
Q
Is any client data or birth information transmitted to external cloud servers?
No. MAREA operates on a 100% client-side local architecture. All mathematical computations and image renderings occur inside your browser memory. No client data is ever collected or stored on external servers.
Q
How do I receive my license key after purchase?
Upon completing your purchase through our Merchant of Record (Paddle), your permanent Pro license key is instantly displayed on the order confirmation screen and delivered directly to your email inbox.
