Display Field: Name

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This dataset quantifies aircraft‑related hazard for each local municipality by integrating flight‑path geometry, airport‑operation influence zones, terrain characteristics, and human‑settlement exposure.InputsWeighted flight‑routes (Ranks 1–10)Airport CTRs, ATZs, runway approach/departure pathsSettlement exposure raster (population/built‑up density)DEM‑derived elevation modifiersMunicipal‑Scale ProcessingThe provincial aviation‑hazard layer was intersected with municipal boundaries.Length‑weighted and area‑weighted hazard summaries were computed.Settlement exposure increased hazard scores in densely populated or high‑infrastructure zones.Elevation modifiers applied where terrain complexity increases operational hazard.OutputA municipal‑level hazard index indicating relative exposure to aircraft movement, useful for:Local disaster managementHuman‑settlement planningInfrastructure safety assessmentsEmergency landing‑risk identificationMunicipal disaster‑risk profilingThe dataset highlights municipalities with greater exposure beneath or adjacent to flight‑operations corridors.
