Spatial data sets from the Andelle Valley Flood Risk Prevention Plan, a key French government instrument for controlling development in at-risk areas. The data includes hazard zones, regulated perimeters, and threatened assets, produced by the Bureau de Recherches Géologiques et Minières and last updated in December 2020.
Use Cases
- Mapping construction ban zones based on described 'red areas' with high hazard levels.
- Analyzing hazard exposure levels by cross-referencing hazard maps with described 'stakes'.
- Identifying 'origins of risk' entities that represent potential threats to the area.
- Planning development requirements in described 'blue zones' where projects are subject to adapted prescriptions.
Strengths
- Data is part of a formal French government Risk Prevention Plan (RPP) framework.
- Includes multiple described spatial data sets such as perimeters, hazard areas, and issues.
- Last updated date is explicitly stated as 2020-12-10.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Last updated 2020-12-10 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
