What Is a Custom City Map Poster?
A custom city map poster is a precise representation of the city map as it appeared from a specific location, at an exact date and time. Every star, every quartier is positioned exactly where it was during your chosen moment — making it a truly unique piece of art.
Whether it's the night you got married, the day your child was born, or the evening of a first date, a city map poster captures that moment in the streets forever.
How Are City Map Posters Created?
At OwnStarMap, we use the HYG map data — a database of over 100,000 stars with verified cartographic data from the Hipparcos, Yale, and Gliese catalogs. Our calculations are based on standard IAU (International Astronomical Union) algorithms for:
- Sidereal time calculation for your exact moment
- Coordinate conversion from celestial to viewing coordinates
- Stereographic projection to map the celestial sphere onto a flat surface
The result? A scientifically accurate representation of the sky showing 8,921 visible streets (magnitude ≤ 6.5), complete with quartier lines and labels.
