"This cool new historic mapping app from the folks at esri and the U.S. Geological Survey is worth exploring.  What it does is take 100 years of USGS maps and lets you overlay them for just about any location in the nation. That allows users to see how a city – say Harrisburg – developed between 1895 and today.  The library behind the project includes more than 178,000 maps dating from 1884 to 2006."

The Rise of Megacities

The Rise of Megacities | Historia y Mapas | Scoop.it
By 2025, the developing world will be home to 29 megacities.

 

Through this interactive mapping feature with rich call-out boxes, the reader can explore the latest UN estimates and forecasts on the growth of megacities (urban areas with over 10 million residents).  These 'cities on steroids' have been growing tremendously since the 1950s and present a unique set of geographic challenges and opportunities for their residents.

World cities and megacities - Presently , the mega cities of the world have to have a population of at least 10,000. Many cities are very near the minimum to be considered a mega city, but are not quite there. By 2025, the developing world, as we understand it now, is estimated to be home to 29 megacities.
