Mapping Orinoco and Caroni River Floods in Venezuela

Mapping Orinoco and Caroni River Floods in Venezuela

Disaster Charter Landsat-based map of flooding in Venezuela
The Disaster Charter made this Landsat-based map of Bolivár State’s flooded areas available to first responders. Heavy rains in August caused wide spread flooding on the Orinoco and Caroni Rivers in Venezuela. This map was made using pre- and post-event Landsat images acquired on May 13, 2016 and Aug. 4, 2017, respectively.

The Disaster Charter used Landsat 8 data to map flooding on the Orinoco and Caroni Rivers in Venezuela with data acquired on August 4, 2017.
The International Charter: Space & Major Disasters, known simply as the Disaster Charter, is a system that supplies free satellite imagery to emergency responders anywhere in the world.
The Charter concept is this: a single phone number is made available to authorized parties providing 24/7 contact to a person who can activate the charter. Once activated, a project manager takes charge. The project manager knows what satellite resources are available, how to task them to collect data, and how to quickly analyze the collected data to create impact maps for first responders. These maps, provided to responders for free, often show where the damage is and where crisis victims are, allowing responders to plan and execute relief support.
You can think of the Charter as a one-stop-shop for impact maps—an essential resource, since in many cases satellite data are the only practical method to assess current ground conditions after a disaster.
