Global Light Pollution Visualization & Analysis
For Astrophotography, Astrophysics & Night Sky Conservation

Disclaimer: This is a personal, non-profit passion project created over weekends with personal funding. I am not a professional cartographer or astrophysicist; I am a developer who loves the night sky. All code and tools are open source (MIT License). While I strive for accuracy using open data, errors may exist. I welcome constructive feedback and collaboration.
