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.
