One of the many ways to keep FEMA maps up to date is by tracking urban change using satellite imagery. Take this suburb of Atlanta, Georgia as an example. By mining Landsat images spanning a 27 year period, it's possible to identify areas where the land surface has permanently changed and affect the areas ability to absorb water.

The river to the Northwest is the Chattahoochee River. The "Y"-shaped roads are Interstate 85 (upper branch) and Route 316 (lower branch). As the years go by, one can see the Mall of Georgia being built in the upper middle part of the screen, immediately north of Interstate 85. Surrounding neighborhoods sprout up throughout this whole area as we move through time.

This animation was created for use in a NASA video on water run-off changes related to urban sprawl titled "FEMA Risk Map".

Animation of a Northeastern suburb of Atlanta from 1984 to 2010 through the eyes of Landsat satellite images. The animation begins with a view of the United States and zooms into the Atlanta suburb, which then cycles through Landsat images of the area from 1984 to 2010. While the animation moves through time, the viewer should be able to see the Mall of Georgia spring into existence along with the growth of all the surrounding neighborhoods.
