--Watch the Ocean Pour Over Cities--

Global Flood Map uses NASA satellite data to show what areas of the world are under water and at risk for flooding if ocean levels rise. Change how many inches the sea level rises and watch the land start to disappear. As sea levels climb, Global Flood Map changes its color coding to show you what areas are flooded, at risk for flooding, and safely above sea level. Use the sidebar to see how many people across the globe are displaced by flooding.

Customize your search by entering in the name of your city, state, or country, or click on individual points for more information – current elevation, elevation after sea level rise, and the number and percentage of people losing homes in that area. The dark blue dots represent land submerged underwater and the lighter blue-green dots represent land at risk for flooding. The left side bar displays the number of people displaced by continent and country.
