The same tree, ten metres tall, drawn at the same scale in both pictures. In December its shadow is six and a half times longer than in June — 29 metres against just over four. Both pictures show the sun at its highest point of the day, in Zurich.
The view computes sunlight from the real terrain, the surrounding buildings and the vegetation.
Slide the time across the day. You see when the sun reaches the terrace and when neighbouring houses or a ridge cast the shadow.
Any date can be chosen. The view computes how long the address is sunlit that day and compares 21 December, 21 March and 21 June.
Contour lines measured from your own address. You see at once whether the neighbouring houses stand higher or lower — and by how many metres.
Terrain, buildings and tree heights come from the official Swiss models. Nothing is estimated, modelled or derived from photographs — the roof shapes are the real ones, and a tree casts its shadow at its real height.
A property found through the official address search. You can open it as often as you like, run through every hour and date and come back later — at no extra cost.
Sun positions are computed for the location and were checked against the JPL ephemeris. The view shows the cloudless case — it does not know the weather.
All of Switzerland. Terrain, buildings and trees are available nationwide.
