Water Supply and Management Schemas (SAGE) are legal planning documents for water resource protection in France. The dataset contains the geographic perimeters of these schemes, established by local commissions and approved by prefects. It was published by the Bureau de Recherches Géologiques et Minières and last updated on March 28, 2019.
Use Cases
- Analyze spatial coverage of water resource protection objectives based on the defined SAGE perimeters.
- Assess compatibility of local land-use plans with water management goals based on the enforceable legal framework described.
- Map the administrative hierarchy of water planning based on the relationship between SAGE and SDAGE (Water Supply and Management Managers Schema).
Strengths
- Legal enforceability is explicitly defined, making the data actionable for planning decisions.
- The description details a clear governance structure involving local commissions and prefectural approval.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Last updated 2019-03-28 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
