This dataset provides a municipal‑level hazard index representing exposure to aircraft movement across KwaZulu‑Natal. Weighted flight‑routes, airport operation zones, elevation modifiers, and settlement‑exposure layers were aggregated within municipal boundaries to quantify the relative aviation‑hazard environment for each municipality. |
