Perimeter of the Libercourt PPRN: Hazard Risk Regulation Boundaries

Boundaries at different stages of development for the Libercourt Natural Risk Prevention Plan (PPRN). The perimeters are defined by official acts and produce effects from specified dates, including prescribed, regulated, and study scopes. The dataset is provided by the Bureau de Recherches Géologiques et Minières and was last updated on April 1, 2019.

Use Cases

• Mapping regulated hazard zones based on the approved RPP scope.
• Analyzing the evolution of risk exposure areas based on prescribed and study perimeters.
• Assessing land-use restrictions based on utility easement boundaries (PM1 for PPRNs).

Strengths

• Boundaries are legally defined by official acts, providing regulatory authority.
• Distinguishes between three key planning stages: prescribed, regulated, and study scopes.
• Last update date is explicitly provided as 2019-04-01.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2019-04-01 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
