The Global COVID-19 Viewer map from September 25 shows the prevalence of COVID-19 cases, defined as the total number of cases per 100,000 people, for the United States and parts of Canada and Mexico since early in the pandemic.

The latest update to the Global COVID-19 Viewer: Population Estimates by Age Group and Sex features enhanced capabilities for visualizing the status and reach of the pandemic around the world, daily and over time since its beginning, and to identify at-risk populations. A pop-up trends graph illustrates daily and 7-day moving averages of COVID-19 cases and deaths for a range of select time scales—one month, three months, six months, and beyond. The graph may be accessed by simply clicking on a country. User-friendly mapping tools let users define a custom area or fly to a location of interest. Users may also easily move up or down administrative levels in many countries and view demographic and urbanization estimates relevant to possible risk factors for the virus. The Viewer was developed by the NASA Socioeconomic Data and Applications Center (SEDAC) managed by CIESIN. The underlying population data are from SEDAC′s Gridded Population of the World (GPW) Basic Demographic Characteristics, v4.11, for the year 2010, with estimates to 2020. The COVID-19 data are from Johns Hopkins University & Medicine Coronavirus Resource Center.

The Geo-Referenced Infrastructure and Demographic Data for Development (GRID3) program managed by CIESIN has released the white paper, “Harmonizing Subnational Boundaries,” on GRID3 efforts to support the harmonization, production, and use of digitized legal/administrative units, operational units, and statistical areas. This work addresses three primary areas: improving and harmonizing operational units; fostering improved collaboration on boundary harmonization among disparate government bodies; and using boundaries harmonization to support census efforts. The paper focuses on case studies in Nigeria, the Democratic Republic of the Congo, and Zambia.

NASA recently published an article on its Earthdata web site about the continued flow of NASA Earth science data during the global COVID-19 pandemic. The article describes how the overall Earth Observing System Data and Information System (EOSDIS) was able to continue processing and distributing many terabytes of data each month even though NASA centers had closed and almost all staff had to shift to remote work. The article also highlights how two of the twelve NASA Distributed Active Archive Centers (DAACs)—the Alaska Satellite Facility DAAC operated by the University of Alaska, and the Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN—have adapted to the changing work environment. CIESIN director Robert Chen, who has served as SEDAC's manager for more than 20 years, noted that this is not the first time that SEDAC has faced major disruptions (9/11 in 2001 and Superstorm Sandy in 2012). Among other efforts, SEDAC has worked to increase virtualization of its systems to strengthen flexibility and reliability.

NASA recently exercised another option year in CIESIN's contract to continue operating SEDAC (through July 2021). CIESIN received an “exceptional″ performance rating from NASA for the option year that ended in July 2020. 

Cascade Tuholske has joined CIESIN for a two-year appointment as an Earth Institute postdoctoral research scientist. Tuholske is a geographer specializing in the integration of global-scale human and environment geospatial data to examine the relationship between urbanization and climate change. At CIESIN, he has begun working with director Robert Chen and associate director for Science Applications Alex de Sherbinin to construct a globally extensive, longitudinal, and fine-scale synthesis of extreme heat events, urban population growth, and the urban heat island effect. His goal is to inform adaptation strategies that reduce the harmful and inequitable impacts of urban exposure to extreme heat. He will also contribute to another NASA-funded project on the use of gridded population and settlement datasets to assess progress towards the United Nations Sustainable Development Goals (SDGs). Tuholske received his PhD in geography from the University of California, Santa Barbara, where he focused on the nexus of climate change, urbanization, and food security in Africa under the guidance of Prof. Kelly Caylor.

The Population-Environment Research Network (PERN) has released several online training modules in English and Spanish on the fundamentals of spatial data integration, geared towards demographers and other population researchers. Developed by Susana Adamo, CIESIN research scientist, and Professor Landy Sanchez of the Center for Demographic, Urban, and Environmental Studies at El Colegio de Mexico (COLMEX), the video-based tutorials draw on pre-packaged data and open source geographic information system (GIS) and Web-based tools. The goals of the online training are to review the fundamentals of spatial data integration, with an emphasis on remote sensing; present an overview of relevant datasets and services (platforms and tools); develop basic skills for linking demographic and environmental data; and expand the use of specialized data sources. Production was supported by the International Union for the Scientific Study of Population (IUSSP) through a grant from the William and Flora Hewlett Foundation. PERN is a scientific panel of IUSSP and a sustained partner of Future Earth, and is hosted by the NASA Socioeconomic Data and Applications Center (SEDAC) managed by CIESIN.

The NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN has released the 2019 annual update to the Natural Resource Protection Indicators (NRPI) and Child Health Indicators (CHI) together with two new spatial data sets developed by former SEDAC project scientists Christopher Small of the Lamont-Doherty Earth Observatory (LDEO) and Deborah Balk of the City University of New York (CUNY).

Natural Resource Protection and Child Health Indicators, 2019 Release supports the annual country selection process conducted by the Millennium Challenge Corporation (MCC), which bases its selection criteria on a basket of governance, social, economic, and environmental indicators. For 2019, the NRPI covers 234 countries and is calculated based on the weighted average percentage of biomes under protected status. The CHI is a composite index for 195 countries derived from the average of three proximity-to-target scores.

Spatial Data from the 2011 India Census, v1 contains gridded estimates of India′s population at 1-kilometer resolution, with two spatial renderings of urban areas: one based on official tabulations of population and settlement type and the other based on the Global Human Settlement Layer (GHSL). The data set was developed by a team led by former CIESIN research scientist Deborah Balk, who is now associate director of CUNY’s Institute for Demographic Research. It is part of SEDAC′s India Data Collection.

VIIRS Plus DMSP Change in Lights, v1 provides changes in brightness and extent of global nighttime lights networks over two decades (1992, 2002, 2013). The nightime lights imagery was sourced from the U.S. Air Force Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS) and the Suomi National Polar-orbiting Partnership (NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) Day-Night Band. It was developed by Christopher Small and several CIESIN geospatial experts. The data set was used to assess urban growth and development in Asian megadeltas, described in a paper published in 2018 in Global and Planetary Change. The data set is part of SEDAC's collection, Satellite-Derived Environmental Indicators.

All of these data are available for free download from SEDAC (registration with Earthdata required). The India and nighttime lights data may be visualized through the SEDAC Map Viewer or open web services.

The NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN has updated two of its online mapping tools with new data and functionality. The latest version of the tool, the SEDAC Global COVID-19 Viewer: Population Estimates by Age Group and Sex, provides new visualizations of COVID-19 data in relationship to population characteristics and other potentially relevant factors. Users may now view rates of COVID-19 cases and mortality per 100k people; age pyramids and population numbers for user-defined areas; trend data on cases at the country, state (province), or county level where available; and more.

The POPGRID Viewer, a tool designed to facilitate visualization and intercomparison of the many different global-scale gridded population data sets now available, has been updated with new and more complete versions of the six population data sets included. Data for two different time periods are now included for three data sets. Users may view any combination of data in a unique four-panel viewer, and then compare population estimates for all six data sets for a specific area of interest. The POPGRID Viewer was developed by SEDAC in support of the POPGRID Data Collaborative, an initiative launched by CIESIN in 2017 to bring together both the developers and users of global georeferenced population data.
