Emprise du lac Léman (complet)Extent of Lake Geneva (complete)
This dataset provides a geospatial layer representing Lake Geneva along with the Rhône and Arve rivers, intended for cartographic production requiring hydrographic elements as surface features. It is compiled from cadastral survey data (land cover) of the Swiss cantons of Geneva, Vaud, and Valais, combined with French data from the IGN (French national mapping agency) covering the French side of the lake basin. The dataset is maintained by the Geneva territorial information system (Système d'information du territoire genevois) and is freely accessible without authentication, supporting national-level mapping and geospatial analysis in Switzerland.Couche représentant le lac Léman, le Rhône et l'Arve pour production de cartes devant comporter un élément hydrographique sous forme de surface. Constituée à partir des données de la mensuration (couverture du sol) des cantons de Genève, de Vaud et du Valais, et des données francaises de l'IGN (sur…
