Spatially accurate and up-to-date population and settlement data are widely used in planning and decision making in both the public and private sectors to improve the effectiveness and efficiency of decisions, monitor impacts, and identify those who might otherwise be left behind. Understanding where people live and work, and the type and condition of their housing and other infrastructure, is critical in times of disaster, enabling emergency responders to reach those most in need more quickly with appropriate assistance. Such data can help improve access to public and private services, increase the sustainability of natural resources, and facilitate progress towards meeting the internationally accepted Sustainable Development Goals (SDGs). The POPGRID Data Collaborative aims to bring together and expand the international community of data providers, users, and sponsors concerned with georeferenced data on population, human settlements and infrastructure.
We promote cooperation in producing and harmonizing high quality data products and services needed by a range of scientific and applied users. We seek to improve data access, timeliness, consistency, and utility; support data use and interpretation; identify and address pressing user needs; reduce duplication and user confusion; and encourage innovation and cross-disciplinary use. We bring expertise and perspectives from diverse natural, social, health, and engineering science disciplines and sectors, and from government, academia, private industry, and nongovernmental organizations.
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.
Currently participating data producers or those wishing to join this consortium can request more information and site access to edit and maintain their content at email@example.com
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.
