Egbert Ludovicus Viele (Vee-lee) was a civil engineer and United States Representative from New York from 1885–1887, as well as an officer in the Union army during the American Civil War.
Viele was author of a color city map, a "Sanitary & Topographical Map of the City and Island of New York," first published in 1865, and now called the "Viele Map", which shows his survey of the original streams, marshes and coastline of New York City, superimposed over the street grid. The map is still used by modern geotechnical engineers, structural engineers and planners to design the foundations of new buildings and structures in the city.
