description: 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.
