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.

Display Field: Name

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: The dataset represents provincial‑scale aircraft‑movement hazard by combining:Flight‑path hierarchy (commercial airways, regional routes, GA paths, helicopter corridors)Airport control zones and approach/departure pathsTerrain and elevation modifiers affecting flight safety marginsAir‑route buffer zones representing operational envelopesHazard WeightingA 10‑to‑1 hazard‑ranking system was applied:10: Primary commercial corridors, major approach cones, controlled airspace (CTR)7–9: Regional routes, controlled low‑altitude corridors4–6: General aviation flight paths, helicopter routes1–3: Low‑probability fly‑over areasWeights reflect aircraft density, aircraft type, altitude, complexity of maneuvers, and potential ground‑exposure risk.Processing ApproachAll flight‑path datasets were merged into a unified aviation‑movement layer.Hazard ranks were assigned per route class.Terrain‑based modifiers increased hazard in areas where elevation imposes operational constraints.Control‑zone buffers were integrated to represent high‑risk airport operations.PurposeSupports:Aviation‑related disaster managementStrategic risk identificationEarly‑warning planningAirport safety‑zone delineationProvincial‑level transport‑risk modellingThe layer represents relative hazard, not observed aviation‑incident frequency.
