EarthCube is a process established to transform the conduct of research through the development of community-guided cyberinfrastructure. Specifically, EarthCube is attempting to integrate data and information knowledge management across the Geosciences; providing capabilities that permit scientists to conduct research in a more productive way, integrating their work with data from other agencies as well as international partners. Thus, EarthCube aims to create a knowledge management system and infrastructure that integrates all Earth system and human dimensions data in an open, transparent, and inclusive manner. EarthCube requires broad community participation in concept, framework, and implementation, and must not be hindered by rigid preconceptions. We were tasked with creating a roadmap for the future governance of EarthCube. This paper provides three complete units for accomplishing this. Part 1 – the Roadmap – provides action items and a timeline for developing and implementing a governance framework. Part 2 – the Roadmap Documentation – provides insight into the ten guidance points presented by the National Science Foundation (NSF) at the onset of this project. Part 3 – provides a complete summary of the research and community outreach conducted to produce parts 1 and 2.
