Toits des bâtimentsBuilding Roofs
This API provides the footprints of above-ground building roofs in the Canton of Geneva, enabling visualization of roof shapes and the orientation of individual roof faces. The data is derived from 3D digitization (projection) of buildings and is published by the Système d'information du territoire genevois (Geneva territorial information system). A related entity class, CAD_BATIMENTS_HORSOL_TOIT_SP, provides complementary information. The dataset is useful for spatial analysis, urban planning, and applications such as solar potential assessment based on roof orientation.Emprises des toitures des bâtiments hors-sol, permettant la visualisation des formes de toitures et l'orientation des faces de celles-ci. Ces informations proviennent de la numérisation 3D des bâtiments (projection). Voir également la classe d'entités CAD_BATIMENTS_HORSOL_TOIT_SP
