Exploratory. Except where marked Confirmed, these landing zones are
derived from terrain analysis and have not been validated by aircrew or
emergency services. Approach paths, surface condition, obstructions and canopy are not
assessed. Do not rely on them for operational decisions.

High - 1m LiDAR DEM + canopy check
Medium - 8m DEM, no canopy data
