This dataset provides detailed segments of watercourses—real or fictitious, permanent or temporary, natural or artificial—located within the Aix-Marseille-Provence metropolitan area. Each segment is homogeneous across all relevant attributes and does not include confluence points. The data forms part of the Hydrography theme of the BD TOPO® reference topographic database. It is published and maintained by the Métropole Aix-Marseille-Provence and is accessible without authentication, making it suitable for mapping, environmental analysis, and local infrastructure planning related to rivers and streams.》Ce jeu de données détaille les portions de cours d'eau, réels ou fictifs, permanents ou temporaires, naturels ouartificiels, homogènes pour l'ensemble des attributs qui la concernent, et qui n'inclut pas de confluent, présents dans le thème Hydrographie de le BD TOPO ® Le thème Hydrographie de le...
