about
nx_geo_query_gate.nx -- GATE for GEO-009 spatial query. Proves:
nearest : among {LA, Boston, Philadelphia}, nearest to NYC is Philadelphia (index 2)
within : within 200 km of NYC = {Philadelphia} only (Boston ~306 km out, LA out)
bearing : due N=0, due E=90, due S=180, due W=270, NE@equator=45 (the compass quadrants)
