US: DigitalGlobe claims that three million people have joined its crowdsourcing platform Tomnod to locate the missing Malaysia Airlines plane. Although, there are no statistical data available about previous such attempts, this initiative by the satellite operator is being called as the largest crowdsourcing project of its kind.
DigitalGlobe on 17 March stated that its search area now has some 24,000 square kilometers (9,000 square miles) and that more images are being added daily, including a new area in the Indian Ocean. The company added that more than three million people have participated in the program, with some 257 million map views and 2.9 million areas tagged by participants. DigitalGlobe's expert analysts will examine the tags to identify the top 10 or so most notable areas and share the information with customers and authorities. The company announced the imitative on 11 March. The company uses an algorithm called CrowdRank to determine the most promising leads, paying close attention to overlap where people tagged the same location.
