Potentiel de surélévation des bâtimentsBuilding elevation-raising potential
This API provides data from a study assessing the potential for adding extra storeys (surélévation) to existing buildings across the Eurométropole de Strasbourg territory. The study was carried out by Upfactor using GIS data from the Eurométropole de Strasbourg, including buildings from the Référentiel à Très Grande Echelle (RTGE), a digital terrain model derived from 2021 LIDAR surveys, and the local urban planning plan (Plan local d'urbanisme). It is published as open data and can support urban planning, densification analysis, and real estate development assessments within the metropolitan area.Etude des potentiels de surélévation des bâtiments sur le territoire de l'Eurométropole de Strasbourg réalisée par Upfactor sur base des données issues du SIG de l'Eurométropole de Strasbourg : bâtiments du Référentiel à Très Grande Echelle (RTGE) MNT d'après le LIDAR 2021 Plan local d'urbanisme...
