Si vous regardez la légende, vous remarquerez que la présence des bâtiments est bien prise en compte.
Non, vous interprétez incorrectement ce que vous voyez. Comme expliqué dans la FAQ :
"None of these models do not take into account terrain, building shielding, atmospheric reflection (e.g. off of inversion layers), or atmospheric opacity (e.g. there are different thermal propagation rates depending on humidity). This is because modeling these effects is much more difficult, and requires accurate information about the terrain, buildings, and atmosphere, which I do not have access to (as of yet), and even if I did, might require computational resources exceeding those of a web browser."
