LNBT hub coverage — Greenland

The whole island. Towns are far apart, so much of the ice sits outside the 15-minute noon window. Product rule: largest nearby catalog city whose solar noon is within 15 minutes of the cell (~3.75° longitude). Compare with unconstrained largest-nearby and pure nearest. Generated 2026-10-06 · step 0.25° · land 10939 cells.

Working verdict: Some strip-like elongation remains. Product noon-cap 15 min: mean noon Δ 25.7 min (was 57.9 unconstrained). 43.5% of land cells change hub vs unconstrained; 31.8% still over cap (sparse catalog fallback).
