Shademap characteristics

Shademap is an interactive website that allows to visualize, at any time of the day and anywhere in the world, where the shadow is projected and where the sun affects. Thanks to a 3D map based on topographic data and buildings models, the tool precisely calculates the position of the sun and the extension of the shadows.

Thus, you can decide whether your walk through the center of Zaragoza will be on the sidewalk of the shadow or the sun, or if it is better to change travel to avoid direct radiation.
