| Description |
National spatial vector dataset mapping water bodies (standing and flowing surface water features) across Metropolitan France, derived from the BD Carthage database framework. The dataset provides detailed polygon and line geometries representing French hydrographic networks, attributed using national nomenclature and administrative codes (SANDRE standards). (Note: Attribute schema utilizes national language and technical codes, requiring cross-reference with SANDRE dictionaries to fully distinguish natural vs. artificial water body designations). |
