This repository contains self-digitized features of early 20th century Manhattan, including the historic street plan, island footprint, and historic progression of and precursors to Broadway. The streets, shorelines, and other transportation features were digitized from the Ohman Map Company's 1906 American Real Estate Company map of New York City. The speculative indian paths were traced from Reginald Bolton's "Indian Paths in the Great Metropolis" from 1912. The Hessian Spring, The Run, Sherman's Creek, and marshes were derived from Knapp's 1870 "Map of that Part of the City of New York North of 155th Street".
