What SunMap Does
SunMap is an interactive 3D shadow analysis tool that helps you understand sunlight patterns at any location on Earth. Whether you're planning a photo shoot, evaluating a property, or installing solar panels, SunMap provides the data you need.
Real 3D Building Shadows
Uses OpenStreetMap building data with accurate heights to render realistic 3D structures. Buildings cast shadows based on astronomical sun position calculations using the SunCalc library.
Any Time, Any Date
Slide through the entire year and any time of day. See how shadows change from summer solstice to winter solstice, and watch shadows move in real-time throughout the day.
Sun Position Data
Displays precise sun azimuth (compass direction) and altitude (angle above horizon) for any location and time. Essential for photographers planning golden hour shots.
Tree & Terrain Shadows
Loads tree locations from OpenStreetMap to show vegetation shadows. Terrain shadow analysis shows how hills and mountains affect sunlight patterns in your area.
