Tracking Urban Change and Flood Risk with Landsat

Release Date:

When it comes to helping communities across the US stay up-to-date on their flood risk, the Landsat satellite can take a bow.

When it comes to helping communities across the US stay up-to-date on their flood risk, the Landsat satellite can take a bow. Landsat images help track urban change, a factor that can impact a community's flood risk. The Federal Emergency Management Agency, or FEMA, uses these images to help identify where they should launch a new flood study. Flood studies determine how prone different neighborhoods are to floods of a certain intensity or likelihood.
