A major milestone for NASA's Socioeconomic Data and Applications Center (SEDAC), has been reached: 100,000 registered users since implementing the registration system back in February 2015, or about 17,000 per year. Note that this includes only the users registering to download data; the SEDAC website receives more than 50,000 visitors a month. SEDAC users constitute about 10% of the registered users in the wider NASA Earthdata Login (EDL) system, which includes 11 of the other sister data centers (DAACs) in the NASA Earth Observing System Data and Information System (EOSDIS), and various other elements and components.
Users who participated in the annual American Customer Satisfaction Index survey gave SEDAC an overall positive evaluation again. The survey assesses user satisfaction with the data, tools, and support provided by the NASA EOSDIS data centers and services, of which SEDAC is the only one to focus on the integration of remote sensing and socioeconomic data.
