Crowdsourcing and citizen science help federal agencies to innovate, collaborate and discover. In this toolkit, you will learn how to design and maintain projects. You can also read through case studies and access additional resources related to communities that practice crowdsourcing and citizen science.
What Is Crowdsourcing?
Crowdsourcing involves an open call for volunteers to provide information or help solve a particular problem. A large group of either unknown or trusted individuals (“the crowd”) responds.
What Is Citizen Science?
Citizen science involves voluntary public participation in the scientific process to form research questions, conduct scientific experiments, collect and analyze data, interpret results, make discoveries, develop technologies and applications, and solve complex real-world problems.
