The POPGRID Data Collaborative is a consortium of data producers, data users, donors, and other stakeholders that seeks to:
- facilitate collaboration among data producers;
- inform users so that they can choose the data most suited to their needs;
- work with users and donors to identify and prioritize data needs; and
- promote collaboration on data validation, documentation, and access initiatives.
POPGRID has been supported by seed funding from the Columbia University Earth Institute's Cross-Cutting Initiatives and the Bill & Melinda Gates Foundation. It is an element of the Group on Earth Observations (GEO) Human Planet Initiative (HPI) and is exploring linkages with key sustainable development data organizations and networks.
