OBS

Le qualificatif matriciel est couramment utilisé pour décrire un système de représentation d'images dans lequel les images sont constituées de petites cellules uniformes disposées suivant un quadrillage. Les images sont de manière caractéristique stockées dans l'ordre du balayage des lignes par le faisceau, soit de gauche à droite, puis de haut en bas d'une ligne à la ligne suivante. Une structure matricielle des images est utilisée dans certains SIG.
