Details
The hex map was generated using the tilemaps
algorithm applied to borough groups separately (Manhattan, Bronx,
Brooklyn/Queens, Staten Island), then rescaled to uniform hex size and
assembled to preserve NYC's overall geographic layout. Island NTAs were
added back using tilemaps::create_island() and positioned to
approximate their geographic locations.
