Excerpt from building base outline database for New York City showing parts of Manhattan, Queens, and Brooklyn

(a) Excerpt from building base outline database for New York City showing parts of Manhattan, Queens, and Brooklyn. Base outlines and height data were used to calculate total building floor areas, which combined with live and dead load values yields a building's mass. (b) The combined building load profile distributed in 100 m-by-100 m cells is shown superposed on the finite element model used to calculate subsidence.
