"Through a major effort by many people we were able to have the Digital Globe satellite make a run over the area on Thursday morning and have the data made available publicly. We have split these images into smaller tiles that can be easily scanned visually and stored into the Amazon S3 storage service. We then created tasks for reviewing these images and loaded then into the Amazon Mechanical Turk Service. This is where you come in. We need your help in reviewing these images to see whether you can locate Jim's boat in any of these images. Please go to the Amazon Mechanical Turk site and help us find Jim Gray.
