six disaster images

"Researchers investigated the use of social media to quickly identify impacted areas in need of assistance following a natural disaster. A and B are satellite images of a flooded road in Colorado after the 2013 floods. C was taken by Civil Air Patrol and shows the same submerged road, identifying with a square a stranded truck. D is the image C after it has been classified for water pixels. E is a close-up of C, showing the stranded truck. F is the same truck in a Flickr post.
