man_made feature or foliage (tree or hedge)? Should it be combined<br>
with seasonal=* for deciduous plants?<br>
<br>
What is the criterion with regard to time of day, like if due to the<br>
angle of the sun, it only provides shade between 11:00-13:00 (the most<br>
important time), before noon or in the afternoon? It can also come<br>
handy to know whether the pavement will still be burning to your dog<br>
if shade only reaches the highway during the afternoon.<br>

<br>
As an alternative, it would be possible to map each and every tree and<br>
hedge, along with its taxon, height and crown_diameter, each fence<br>
with fence_type and each building and other structure in 3D, each<br>
sidewalk with exact material and geometry and compute shading based on<br>
that, but this sounds like much more work and it is implausible in<br>
most parts of the world in the foreseeable future (and not required<br>
for solving the problem at hand to a given approximation anyway).<br>
