Vietnam Flooding

With the threat of more torrential rains in Southeast Asia, NASA is able to help pinpoint where critical emergency food supplies must first be sent. The MODIS instrument onboard the Terra satellite produces images that are used in a global flood monitoring system. After converting available satellite imagery into precise geographical information, this precious data is available to the science community via the World Wide Web, and is used by the United Nations World Food Program staff.

Wide Image of the Vietnam flooding
The MODIS instrument on board the Terra satellite created 8-day composite images of the precise location of flooded areas along the Mekong River in Cambodia and Vietnam. These composite images are blended together to produce one image that combines all cloud-free views. These data sets were collected on June 8-16, July 19-26, August 20-27, and August 28-Sept 4, 2000.  To the right is the mapped image of the flooding.

Wide and Mapped images are from a zoom in of image one.
