# Light Pollution Map

> Light Pollution Map is an interactive web application that displays global light pollution data using the Bortle Scale and SQM measurements, helping users find optimal locations for stargazing, Milky Way viewing, and aurora observation.

This website provides comprehensive light pollution data sourced from NOAA's VIIRS, presented through an interactive map interface. Users can search for specific locations, view Bortle Scale classifications, and access detailed information about night sky visibility in any geographic area.

## Core Information
