The Hudson river shoreline of Manhattan changed dramatically during the last five decades. The two historical aerial photographs illustrate the amount of change that has occurred at this portion of Manhattan between 1954 and 2009. As the 1954 historical aerial photograph shows, the piers along the Hudson river were still actively used at that time. Eventually, shipping activity shifted to the New Jersey side of the Hudson river. In 1973 what were once Piers 1 through 21 were buried under landfill from the World Trade Center construction project and became Battery Park City. The ongoing construction of the new World Trade Center buildings ensures that this portion of Manhattan will continue to change significantly in the near term.

These two historical aerial photographs show how much Las Vegas, Nevada has changed during several decades of very rapid growth, multiplying its size several fold during those years. The historical aerial photograph on the top was acquired in 1973 and the aerial on the bottom is a mosaic of photographs acquired in 2010. The city has expanded into the adjacent desert with particularly strong growth in the western portion of the city. High resolution aerial photography of sections of the city also show on a more detailed scale how rapidly certain portions of Las Vegas have changed during very short periods of time. Particularly dramatic are the changes during the 1990s in the northwestern portion of the city.
