Comparison map of global subnational infant mortality rates shows version one (with data from circa 2000) and the recently updated version two (with data from circa 2015). The inclusion of higher resolution infant mortality rate input data, one of the features of version two, is particularly visible in Africa.

An updated version of the Global Subnational Infant Mortality Rates (IMRv2) data set has been released by the NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN, with more recent (circa 2015) and higher resolution input data. IMR data have been collected for 234 countries and territories, of which 143 include subnational units and 91, mostly smaller nations, include only national units. Compared to version one of the Global IMR data set, which was benchmarked to the year 2000, version two has 78 more countries with subnational data, and the average input unit size has declined. As a georeferenced global subnational dataset of infant mortality rates, IMRv2 has many potential applications that may be of interest to a wide user community in interdisciplinary studies of health, development, sustainability, and the environment, as well as policy making. The IMRv2 data set is part of the SEDAC Poverty Mapping collection, an extensive group of data sets related to various aspects of the geographic distribution of people living in poverty.

CIESIN information technology staff travelled to Washington DC recently to learn about the latest geographic information system (GIS) technologies and trends showcased by the software giant Esri at its annual gathering for developers, the 2019 Esri Developers Summit DC, held January 31 at the Walter E. Washington Convention Center. CIESIN associate director for information technology Sri Vinay, senior systems analyst and programmer Frank Pascuzzi, and senior media designer Al Pinto focused on innovative technologies and best practices for improving the organization’s capabilities for Esri’s ArcGIS, the GIS software used widely by today’s geospatial community. The overall goal is to improve the infrastructure that supports geospatial data development, mapping, and the implementation of geoprocessing services at CIESIN and its main program, the NASA Socioeconomic Data and Applications Center, including the development of web and mobile mapping applications.

Earth science data creators, system developers, stewards, disseminators, and users met in Bethesda, Maryland, for the Winter Meeting of the Federation of Earth Science Information Partners (ESIP) January 14–17. Beginning in 2019, the theme of the ESIP meetings, held twice a year, is “Increasing the Use and Value of Earth Science Data and Information.” Robert Downs, CIESIN senior digital archivist, participated in the meeting, representing the NASA Socioeconomic Data and Application Center (SEDAC), one of the original ESIP members. During the business meeting of the ESIP Assembly on January 16, Downs was re-elected as the Type 1 Representative on the ESIP Governance Committee. At the meeting, he presented the poster, “Assessing Data Curation at a Scientific Data Center,″ authored with Robert Chen, CIESIN director and SEDAC manager, and Alexander de Sherbinin, CIESIN associate director for Science Applications and SEDAC deputy manager. 

More than 24,000 Earth scientists and other experts traveled to Washington DC December 9-14 for the annual American Geophysical Union (AGU) fall meeting, held at the Walter E. Washington Convention Center. The meeting provided a unique opportunity to showcase recent developments in research, data, and tools developed by CIESIN and its partners and to network with a diverse community of scientists, policy experts, and practitioners. CIESIN director Robert Chen organized and co-chaired two sessions highlighting innovations in mapping human settlements, population, and infrastructure, and gave three presentations on the integration of socioeconomic and remote sensing data in support of sustainable development research and applications, including a “flash talk” at NASA′s exhibit booth. Senior digital archivist Robert Downs co-chaired sessions in the Earth and Space Science Informatics (ESSI) and Education tracks, and co-authored a number of oral, “e-lightning,” and poster presentations on various data management topics. He also served as a judge for student papers in the ESSI track. GIS programmer Kytt MacManus described CIESIN′s decision support tools for flood and sea level rise planning and presented a poster on the geoprocessing services and Web mapping tools available from the NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN. Associate research scientist Sylwia Trzaska described her work on climate adaptation planning and as leader of a new project under way to map hard-to-reach populations in rural mangrove areas of West Africa. Greg Yetman, associate director for geospatial applications, presented the latest results from CIESIN′s collaboration with Facebook on high resolution population mapping, and contributed to a number of other presentations by CIESIN staff members and partners.

The meeting also provided the opportunity for CIESIN to hold an informal side meeting of the POPGRID Data Collective December 14 at the Henley Park Hotel. The meeting brought together more than 20 experts from the Washington DC area to review progress and develop plans for the next phase of POPGRID, which has received additional funding support from the Bill & Melinda Gates Foundation.

CIESIN has released a new Web site and mapping tool designed to help users learn about the growing number of gridded population data sets, and make decisions about which data sets may be the most useful for their needs. The POPGRID web site and viewer were developed under the auspices of the POPGRID Data Collective, an initiative launched by CIESIN in 2017 with support from the Earth Institute, the Bill & Melinda Gates Foundation (BMGF), and the NASA Socioeconomic Data and Applications Center (SEDAC). The POPGRID web site provides users with detailed background information and documentation, as well as direct links to the data and data sources.

The POPGRID Viewer incorporates a four-panel display of population count data available from six different data sets: the Gridded Population of the World (GPWv4.10) 2015 count developed by SEDAC; Landscan 2015 developed by Oak Ridge National Laboratory; WorldPop Estimates 2014 from the WorldPop project; Global Human Settlement Population Grid 2015 (GHS-POP) developed by the European Commission’s Joint Research Centre and CIESIN; the Esri World Population Estimate 2016 (WPE); and the High Resolution Settlement Layer (HRSL) developed by the Facebook Connectivity Lab and CIESIN. Users may zoom in on a location of interest anywhere in the world and see the population estimates for four of the six data sets at the same time. A single-panel mode lets users compare national-level metadata across the data sets and draw a polygon or rectangle to obtain an intercomparison table and chart containing customized estimates from all six population data sets (when available). Users of Geographic Information Systems (GIS) may also supply a shapefile to obtain the population estimates for a specific region with a complex shape.

Direct comparison of these data sets is important because they are based on different data sources and methodologies that may affect their usability for different purposes. For example, the GPWv4.10 data are based solely on Census data for subnational administrative units, assuming a uniform distribution of population even in large rural districts. Other data sets utilize high-resolution remote sensing data combined with machine-learning algorithms to allocate population to built-up areas. In addition, some data sets use additional inputs such as distance from roads, slope, and other factors to model population distribution at high resolution. The data sets also differ in the time periods covered, the quality and consistency of inputs in different regions, and the demographic characteristics estimated (e.g., age groups). These differences may make the data more useful for some applications, such as assessing potential exposure to extreme events or climate change, but less useful for others, such as estimating the number of vaccines needed in an area of interest.

The POPGRID Data Collective was established to bring together and expand the international community of data providers, users, and sponsors concerned with georeferenced data on population, human settlements, and infrastructure. POPGRID seeks to promote cooperation and reduce overlap in producing data, and to encourage trans-disciplinary use and development of data, among other related goals. CIESIN led the initial phase of POPGRID, and is working with the Global Partnership for Sustainable Development Data (GPSDD) and the Thematic Research Network on Data and Statistics (TReNDS) of the United Nations Sustainable Development Solutions Network (UNSDSN) to initiate a second phase of POPGRID with support from BMGF. POPGRID is also contributing to the Group on Earth Observations (GEO) Human Planet Initiative, which aims to improve the quality and accessibility of data needed for assessing humanity’s impact on the planet, access to resources, and exposure to risk.

Two Webinars led recently by CIESIN staff featured data products distributed by the Socioeconomic Data and Applications Center (SEDAC) managed by CIESIN.
