Crowd-sourcing in ICT4D

Dr. Stephen Ward’s lecture to our class on the importance of crowd-sourcing really opened my eyes to ways the technology could be used in ICT4D. While in the western world crowd-sourcing has been used to improve websites but also provide controversial marketing information to advertising agencies and corporations, the concept as a whole was repurposed by “DigitalGlobe”, which uses GIS and satellite imaging technologies, to launch their crowd-sourcing platform “Tomnod” in an effort to assist locating the lost Malaysian plane in early March. Developments in crowd sourcing and GIS satellite technologies opened up the information source to thousands of users who were able to provide up to date information on the whereabouts of the plane. Applying crowd-sourcing to other endeavors in ICT4D to provide up to date and accessible information to those in the developing world on their surroundings could be endlessly useful in the coming years not only in disaster prevention but also in instituting projects who’s success depends on the nature of the landscape. DigitalGlobe’s five high-resolution imaging satellites were able to capture more than 3 million square kilometers of earth imagery each day, providing an incredible volume of imagery that would have been overwhelming were it not for the “Tomnod” crowdsourcing mechanism. The efforts of millions of online volunteers around the world helped DigitalGlobe rule of some of the major oceanic areas in order to hone in on more likely locations, leading to a more efficient search process.
