This dataset quantifies aircraft\u2011related hazard for each local municipality by integrating flight\u2011path geometry, airport\u2011operation influence zones, terrain characteristics, and human\u2011settlement exposure.<\/SPAN><\/P>

Inputs<\/SPAN><\/P>

  • Weighted flight\u2011routes (Ranks 1\u201310)<\/SPAN><\/P><\/LI>

  • Airport CTRs, ATZs, runway approach/departure paths<\/SPAN><\/P><\/LI>

  • Settlement exposure raster (population/built\u2011up density)<\/SPAN><\/P><\/LI>

    Municipal\u2011Scale Processing<\/SPAN><\/P>

    1. The provincial aviation\u2011hazard layer was intersected with municipal boundaries.<\/SPAN><\/P><\/LI>

    2. Length\u2011weighted and area\u2011weighted hazard summaries were computed.<\/SPAN><\/P><\/LI>

    3. Settlement exposure increased hazard scores in densely populated or high\u2011infrastructure zones.<\/SPAN><\/P><\/LI>

    4. Elevation modifiers applied where terrain complexity increases operational hazard.<\/SPAN><\/P><\/LI><\/OL>
