Shadeline: 3D Shadow Map

Shadeline shows where sunlight and shadow fall on a real 3D map, for any place on Earth and any moment of the year. Search for an address, drag the time slider and watch the shadows of real buildings and terrain move across streets, roofs and facades. Use it before you rent or buy a home, plan a terrace or a garden, place solar panels, or scout a photo. SUN AND SHADOW IN 3D • Buildings from OpenStreetMap and real terrain, worldwide • Shadows cast by buildings and by hills • The sun's path across the sky, drawn over the map • Azimuth, elevation, sunrise, sunset, solar noon and day length, in the local time of the place you are looking at • Civil dawn and dusk, and the morning and evening golden hours ANY DAY, ANY HOUR • Slide through the day or press play to animate it • Jump to the equinoxes and solstices with one tap • Pick any date, past or future • Compare the solstices or the equinoxes side by side SUN-HOURS MAP • Compute how many hours of direct sun every point of an area gets on the day you choose • Areas of 200, 400 or 800 metres • See the average and the share of the area that gets under one hour of sun POINT REPORT • Tap the ground, a roof or a facade • Direct sun on the chosen day and sun hours over the year • Annual solar irradiation in kWh/m², month by month, using NASA POWER climate normals • Shading loss and sky view factor • Export the figures as CSV, save the map as an image, or copy a summary TRY A CHANGE • Raise or lower a building, or hide it, and see how the shadows change • Set the height used for buildings whose height is missing from the map SAVE AND SHARE • Save a view and come back to the same place, camera and time • A link keeps the place, the camera, the date and time, and your building edits • Short links for messages and email GOOD TO KNOW • No account, no ads, no analytics • English and Azerbaijani, light and dark themes • Needs an internet connection to load the map • Sun positions use the NREL Solar Position Algorithm. Shadows and energy figures depend on open map data: building heights can be missing or out of date, and trees are illustrative. Treat the results as estimates, not as a certified study.
