Das Gelände, auch Relief, Terrain oder Topografie, ist die natürliche Erdoberfläche mit ihren Höhen, Tiefen, Unregelmäßigkeiten und Formen.

Le relief est la forte variation verticale d'une surface solide, soit positivement, en saillie, soit négativement, en creux. Ce mot est souvent employé pour caractériser la forme de la lithosphère terrestre.

Un terrain est une parcelle de sol possédant une forme et des dimensions précises.
