Integration of remote sensing and population data: Lessons from the NASA Socioeconomic data and applications center

Many of the core research questions of the anthropocene are spatial in nature, and require spatial data integration to provide the answers: Where are populations most vulnerable to environmental changes located? How do global environmental changes affect people, ecosystems or production systems in a given location? What are the impacts of human activities in the coastal zone, or mountainous areas, or drylands? This paper provides examples of the integration of remotely sensed biophysical data with population data that illustrate the benefits of spatial data integration. It also addresses some of the challenges in integrating data developed at different scales and for different purposes, sharing lessons learned from twenty years of operating the NASA Socioeconomic Data and Applications Center (SEDAC).
