Regular grid model of the emerged coastal strip, with a resolution of 50 cm, which indicates the orientation of the slope at each point of the terrain with respect to north.

El model digital d'ombres de l'AMB és una representació digital de la il·luminació de la superfície del terreny suposant que el Sol es troba a un azimut de 315º i una elevació de 45º respecte de l'horitzó, mitjançant una malla regular de 0,5 metres de mida del píxel. El valor d'il·luminació es representa en escala de grisos, de 0 negre a 255 blanc. Està elaborat a partir del Mapa Topogràfic Metropolità 1:1000 i per tant cobreix l'àrea metropolitana de Barcelona, excepte part dels municipis de Begues i Castellbisbal (dades del 2016). Es distribueixen dues variants del model: la primera està elaborada a partir del Model Digital del Terreny (MDT) i la segona a partir del Model Digital de Superfície (MDS). El MDT es un model del terreny que no inclou els objectes que hi ha a sobre (com arbres, ponts, construccions). El MDS es un model del terreny que inclou alguns objectes que hi ha a sobre (ponts i algunes construccions, però no edificis).
