Aerial map of Manhattan
In the 1920s, a series of extremely detailed aerial photographic maps were made of the island of Manhattan in New York City. These were some of the first maps created by taking photographs from an airplane flying overhead.
Previously, maps had to be made by surveyors making measurements on the ground, which was very time-consuming for a densely developed area like Manhattan. Aerial photography allowed for rapidly mapping the entire island from a bird’s-eye view.The aerial mapping project was carried out by a team from the Fairchild Aerial Camera Corporation. They used special large-format cameras mounted onto the underside of airplanes to capture overlapping photographs of every city block from above.
Over 100 hours of flight time were required to photograph the entire 22.8 square mile area of Manhattan at a very high resolution. Thousands of individual photos were meticulously combined into mosaics to form the final maps.The resulting 1924 aerial maps of Manhattan depicted every building outline, street, park, and infrastructure element in incredible detail. They were the most accurate and comprehensive maps of Manhattan ever made at that time.
These pioneering Manhattan maps demonstrated the potential of aerial photography to produce high-quality maps much more efficiently than ground surveying methods, especially in urban environments.Aerial mapping revolutionized the fields of cartography, urban planning, and landscape analysis. The iconic Manhattan images also helped popularize the possibilities of this new perspective from above.

The document traces the remarkable 10,000-year journey of mapmaking, from the earliest cave drawings to modern digital maps. It highlights significant milestones in cartography, including the Babylonian Map of the World, Ptolemy’s Geographia, the Tabula Rogeriana, and the Mercator projection.
The evolution of maps reflects humanity’s relentless quest to understand and navigate the Earth.
