A Gamification Framework for Volunteered Geographic Information
2015Using crowdsourcing methods to gather large amounts of useful geodata presents many challenges. One challenge is to attract volunteers to participate in crowdsourcing activities. Several studies conclude that to encourage crowdsourcing it is necessary to take into account people’s intrinsic motivation (e.g. fun, altruism, ambition).
