Périmètre des études d'impact sur l'environnementPerimeter of Environmental Impact Assessments
This API provides a geographic dataset showing the location of projects that have undergone an environmental impact assessment in the canton of Geneva, Switzerland. It includes roughly-drawn perimeters delineating the assessed areas along with the names of the corresponding projects. Additional information about specific projects can be requested from the relevant impact-assessment service. The dataset is maintained by the Système d'information du territoire genevois (Geneva territorial information system) and is freely accessible without authentication, making it useful for spatial planning, environmental review, and land-use research at the local level.Cette classe d'objets donne la localisation des projets ayant fait l'objet d'une étude d'impact sur l'environnement. Les périmètres (tracés relativement grossiers) ainsi que les noms des projets sont disponibles. The information supplémentaires peuvent être obtenues sur demande au service d'étude d…
