Photoreal, not diagrams
Actual buildings, actual rooftops, actual trees — streamed from Google's photorealistic 3D imagery. Not extruded grey blocks.
Photoreal 3D · Nothing to set up
Find out where the shadows actually fall.
Real sunlight over real buildings, in the best-looking 3D city you can get in a browser. No account, no upload, no CAD. Open it, drag the sun, and watch the shadows move.
Above: the City of London, 21 June, 17:30 — captured in Sun Map
Same spot, six months apart
Sun Map reads the real solar geometry for a place and a moment. These are its own figures for central London at 12:30 solar time.
21 June, midday
0.5×shadow length
Sun 61.4° above the horizon
21 December, midday
3.8×shadow length
Sun 14.7° above the horizon
The simple one, with the best picture.
Serious solar analysis suites want your CAD models, a project setup and an afternoon to learn. Sun Map is for the other 95% of the time — when you just need to see it.

No account, no file import, no project to configure. The map is running about as fast as this page loaded.
Honest numbers on screen
Sun altitude, compass direction and shadow length for the exact spot and moment — not a slider that only changes a picture.
Every number on screen comes from the actual sun.
No sliders that only change a picture. Move the time and the altitude, direction and shadow length all recompute for the exact spot you're standing on.
Where does the light fall, and what would I actually see?
Most tools answer one or the other. Sun Map keeps the sun, the shadows and your viewpoint in the same place.
Watch real shadows move
Drag through the day and the shadows sweep across the city with it. Pick a date and compare a June morning against a December afternoon on the same building.

Worth knowing before you rely on it
What does Sun Map show?
A real 3D city with the sun placed at the correct height and direction for the date and local solar time you choose. It is a fast way to see when a building, garden, balcony, street or public space is likely to be in sun or shade.
Can I check the view from a specific window?
Yes. Once the detailed 3D city has loaded, click a visible window, roof or ground position. Sun Map moves the camera there so you can look around, walk through the scene and keep changing the time.
What is free and what needs Pro?
The map, the full time-of-day control and the click-to-view camera are free with no sign-up. Sun Map Pro unlocks every date from 2020 to 2035, which is what lets you compare seasons on the same building. Pro is £10 a month in the UK and $12 a month elsewhere.
How accurate is it?
Two different things are worth separating. The sun positions come from established solar geometry and are dependable. The city is streamed photogrammetry, so windows, trees, recent construction and fine detail may be simplified, missing or out of date — treat the geometry as indicative, not surveyed.
Is this a professional survey?
No. Sun Map is a visual exploration tool. Important planning, legal, property or solar decisions should be checked by a qualified professional with measured data.
