2025 marks the bicentennial of the Erie Canal, and NASA's Earth Observatory commemorated the milestone with a satellite-based image tracing the canal's historic route across New York State.
What is it?
According to NASA's Earth Observatory, the image combines shoreline data with the "Blue Marble: Next Generation" base map, which is constructed from imagery collected by NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) aboard Earth-scanning satellites.

This image was taken from orbit above the Erie Canal.
Why is it amazing?
The Erie Canal was one of the defining projects of early America. Construction was completed in 1825, despite the lack of trained engineers at the time. Builders, often self-taught and guided by trial and error, created what was dubbed the "Erie School of Engineering." They devised solutions to challenges such as the Niagara Escarpment near Lockport, where 83 locks were needed to manage the elevation changes, and they built aqueducts to carry the canal over rivers and streams.
Beyond its engineering feats, the canal spurred growth and settlement along its route. Cities like Rochester, Syracuse and Buffalo flourished, transforming from small towns into the industrial and commercial hubs they are today.
