This dataset from the Système d'information du territoire genevois (Geneva canton territorial information system) covers underground buildings, defined as durable constructions built below ground level for at least half of their surface area and used for housing, craft activity or industry in a broad sense. The basement or underground portion of an above-ground construction is only cadastrally recorded if it significantly exceeds the footprint of the structure above it. The dataset supports cadastral mapping and spatial planning within the canton of Geneva, Switzerland.Les bâtiments sous-sol sont des constructions durables, établies sous le sol pour au moins la moitié de leur surface et servent à l'habitat, à l'artisanat ou à l'industrie au sens large.Le sous-sol d'une construction hors-sol n'est cadastré que s'il dépasse de manière significative l'enveloppe du b…
