About 70 experts from academic, government, and private sector organizations met December 14‒17, 2016, at the Pench Tiger Reserve in Madhya Pradesh, India, for the Central Indian Landscape Symposium (CILS). Pinki Mondal, senior research associate at CIESIN, was a co-organizer of the 2016 Symposium, which focused on the theme, “Reconciling Development, Livelihoods and Conservation Goals.” She also co-chaired the session, “The Future of Water, Climate, and Agriculture,” and gave an oral presentation, “Implications of Agricultural Intensification for Diet and Nutrition in Central India.” The Symposium concluded with a presentation by Praveen Pardeshi, principal secretary in the Chief Minister’s Office in Maharashtra. Local partners in organizing the Symposium included the World Wildlife Fund-India and the Satpuda Foundation.
Building on more than 20 years of effort to improve mapping of human population, the fourth version of the Gridded Population of the World (GPWv4) data collection has been released. This new version provides scientists, applied users, and the general public with a more detailed and consistent view of the spatial distribution of population over two decades, designed to support interdisciplinary understanding and analysis of the interactions between human and environmental systems.
GPWv4 includes population estimates and projections at five-year intervals from 2000 to 2020 at a higher resolution than previous versions: 30 arc-seconds, or approximately 1 kilometer (0.6 miles) at the equator. GPWv4 reflects data from the 2010 round of national censuses, which occurred mainly between 2005 and 2014. The NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN collected and carefully matched population and boundary data for more than 13 million subnational administrative units, a 31-fold increase over version 3. Improved data were obtained for more than 100 countries including many small-island nations.
Grids of population counts and density, land area, water area, and data quality indicators are available for free download. Two different sets of population grids have been produced, one reflecting population totals reported by each country and another adjusted to national statistics developed by the United Nations (UN). Files may be downloaded for use in Geographic Information System (GIS) software or other analysis packages. The collection also includes a data set of the central point locations for subnational administrative units, for users needing tabular or vector (point) data.
In addition, SEDAC offers a range of map services and clients to visualize and access GPWv4 data, including the SEDAC Map Viewer, the Population Estimation Service, and the Hazards and Population (HazPop) mobile app for iOS devices. Several of these clients enable users to estimate the population residing within a user-defined circle or polygon, based on GPWv4 data for the year 2015.
GPWv4 is unique in characterizing population distribution based only on national census results, which enables it to be compared and combined with other types and sources of data. Other gridded population data products such as those available from the WorldPop project, the European Commission′s Joint Research Centre (JRC), and the Oak Ridge National Laboratory (ORNL) utilize additional data layers to model population distribution, which may preclude their use for some research and applications. CIESIN has been collaborating with the JRC, Facebook′s Connectivity Lab, WorldPop, and other groups to produce complementary gridded products consistent with GPWv4, such as the Global Human Settlements Population Grid (GHS-POP), the High Resolution Settlement Layer (HRSL), and the planned WorldPop global layer. Gridded population products are useful in diverse applications such as estimating population exposure and vulnerability to natural and technological hazards, determining accessibility to markets or services, and managing land, water, and ecosystem resources.
SEDAC is working to add additional gridded variables to the GPWv4 data collection, including data on age structure, gender, and urban vs. rural population, which should be available by mid-2017. GPWv4 data are made available openly at no cost under a Creative Commons Attribution 4.0 International License (CC-BY-4.0). Users are asked to register using a NASA Earthdata login when downloading data from the SEDAC site. SEDAC is one of the Distributed Active Archive Centers (DAACs) in NASA's Earth Observing System Data and Information System (EOSDIS), and has the mission to develop and operate applications that support the integration of socioeconomic and earth science data and to serve as an “Information Gateway″between the earth and social sciences.

The NASA Socioeconomic Data and Applications Center (SEDAC) has released two new data sets, the Global Urban Heat Island (UHI) Data Set, v1 (2013) and the Global Summer Land Surface Temperature (LST) Grids, v1 (2013). The UHI data set maps average summer day-time maximum and night-time minimum LSTs for urban areas, as well as the LST difference between urban areas and 10-kilometer buffers surrounding the urban areas. The latter represents a measure of the urban “heat island” effect, the temperature difference between urban and surrounding rural areas stemming from differences in land cover (e.g., buildings and asphalt versus trees and grass). The LST grids are derived from the Level-3 Moderate Resolution Imaging Spectroradiometer (MODIS) Version 5 global daytime and nighttime LST 8-day composite data (MYD11A2) from the NASA Aqua satellite. The UHI and LST data sets are useful for research and applications related to human health, weather extremes, and environmental change.
Alex de Sherbinin, associate director for Science Applications and deputy manager of the NASA Socioeconomic Data and Applications Center (SEDAC), presented the NASA Earthdata Webinar, “Remote Sensing-Derived Environmental Indicators for Decision Making,” November 21 and again on November 28. He summarized results from a NASA-funded pilot study to develop policy-relevant indicators from remote sensing data in three issues areas: ambient air pollution, coastal eutrophication, and biomass burning. The Webinar included description of indicator criteria relevant to policy and technical audiences as well as a review of the underlying satellite data and methodologies. Several SEDAC data sets derived from satellite data were also highlighted, including time series global grids of PM2.5 (particulate matter at 2.5 microns), a global urban heat island (UHI) data set, and a forthcoming time series global NO2 (nitrogen dioxide) grid. The Webinar, part of a NASA series, was repeated on November 28 due to the high level of interest, attracting at least 180 participants during the two sessions.
New high-resolution population data has been released, that will help us understand better how people are distributed in many countries throughout the world. The High Resolution Settlement Layer (HRSL) data set was developed by Facebook, CIESIN, and the World Bank as part of a larger effort by Facebook’s Connectivity Lab to develop technologies to connect people in rural areas to the Internet. First, state-of-the-art computer visioning techniques identified buildings from high-resolution commercial satellite images. The data was then combined with census data to generate population estimates, and the results were validated. Data are now available for five countries: Ghana, Haiti, Malawi, South Africa, and Sri Lanka, with data for additional countries expected in the coming months. To download the data, and for more information, go to http://ciesin.columbia.edu/data/hrsl/.

The NASA Socioeconomic Data and Applications Center has recently released new versions of several different interactive mapping tools that provide users with new ways to visualize, analyze, and utilize geospatial data on population, environment, hazards, and related topics. These tools enable users to compare different data sets at local to global scales, to identify the number of people exposed to natural hazards or environmental extremes, and to utilize their mobile devices to assess their location relative to recent hazard events.
Version 2 of the SEDAC Map Viewer now implements an innovative four-window map view to make it easier to compare data layers from SEDAC’s diverse data holdings. Users may arrange the windows to show different maps for the same geographic region, focus in on different parts of the world for a single map layer, or illustrate changing spatial patterns over time. For example, a user could compare current population, land use, and urban expansion potential across Europe or Asia, visualize air quality levels in different urban areas around the world, or utilize the Anthropogenic Biomes data collection to visualize long-term land use change over three centuries, 1700–2000. The viewer supports toggling between the four windows and a more traditional single-window view, as well as direct links to download data for interest.
The SEDAC Population Estimation Service, which provides estimates of the number of people residing in an area of interest without having to download and analyze large amounts of spatial data, has been updated with data from the new Gridded Population of the World Version 4 (GPWv4) data set, including estimates for the years 2000, 2005, 2010, 2015, and 2020. The SEDAC Population Estimator Web App enables users to draw a polygon or circle around an area of interest, and then calls on the Population Estimation Service to obtain an estimate of the population in 2015 living in that area. Those who develop their own mapping tools are free to access and utilize the Service through open international standards.
SEDAC′s mobile application for iOS devices, the Hazards and Population Mapper (HazPop), has also been updated with GPWv4 data. The app displays recent data on hazards such as earthquakes, tornados, and fires, and selected remote sensing imagery from NASA satellites, in conjunction with population and infrastructure data. It also supports location-based services such as estimating the total population near a user′s current location, a recent hazard event, or other point of interest or setting monitoring areas and proximity alerts. HazPop version 1.3 is available free of charge through the Itunes store.
Robert Downs, CIESIN senior digital archivist, traveled to St. Petersburg, Russia, November 7–10 for the thirteenth plenary meeting of the Group on Earth Observations (GEO), a voluntary partnership of governments and organizations working to develop coordinated, comprehensive, and sustained earth observations and information.

The Platform continues the work of the Nansen Initiative, supporting implementation of the 2015 recommendations of the Nansen Initiative Agenda for the Protection of Cross-Border Displaced Persons in the Context of Disasters and Climate Change, known as the Protection Agenda. The Advisory Committee provides expert strategic input to the chair and the steering group of the Platform, and helps implement Platform activities. Adamo and de Sherbinin bring to bear longstanding expertise on environmental migration and displacement, particularly as related to climate change. Based in Geneva, Switzerland, the Platform is supported by the governments of France, Germany, and Switzerland and the MacArthur Foundation.
Ensuring that research data can be used interoperably to further science and societal applications requires clarity on data rights from both the data provider and data user perspectives. Unfortunately, legal rights regarding research data vary widely across national jurisdictions, scientific disciplines, and legal and scientific practice, creating uncertainty and complexity when users attempt to work with data from multiple sources and disciplines. To address this challenge, the Research Data Alliance (RDA) and Committee on Data for Science and Technology (CODATA) formed a joint interest group on the Legal Interoperability of Research Data in 2013. This group has recently released the document, “Legal Interoperability of Research Data: Principles and Implementation Guidelines.” The principles and guidelines provide high-level guidance to all members of the research community—funders, data center managers, librarians, data archivists, scientific publishers, policymakers, university administrators, individual researchers, and their legal counsel—who are engaged in the access to and reuse of research data from diverse sources. CIESIN director Robert Chen serves as one of three co-chairs of the interest group and is a co-author of the new document. A process for endorsement of the principles is under development.
Several different CIESIN staff members contributed to two recent Web-enabled seminars. The Webinar, “Mapping SDG Data Needs to Maize Intensification Plans,” featured five commissioned papers that synthesized recent scientific research on connections between maize intensification and the Sustainable Development Goals (SDGs), with a focus on identifying possible actions within the SDG framework. Senior research associate Pinki Mondal was lead author of the paper, “Potential of Ecological Intensification of Maize in Sub-Saharan Africa for Achieving Nutrition Goals,” co-authored with Harpinder Sandhu of Flinders University, Cheryl Palm of the University of Florida, and Jessica Fanzo of Johns Hopkins University. The Webinar, which included two 90-minute sessions October 25–26, was organized collaboratively by the International Maize and Wheat Improvement Center (CIMMYT) and the Earth Institute, with funding from the U.S. Agency for International Development. Bram Govaerts, associate global director of the CIMMYT Global Conservation Agricultural Program, moderated the Webinar, and CIESIN deputy director Marc Levy served as a discussant, highlighting how data support good decisions in multiple ways, and how high-value and low-cost data options often emerge. CIESIN program manager Minal Patel managed the project. Approximately 100 people attended, including CIMMYT staff in Mexico and eight other CIMMYT global hubs.
Senior digital archivist Robert Downs was one of several presenters in the 2016 GEOSS Interoperability Workshop organized by the Global Earth Observation System of Systems (GEOSS) Standards and Interoperability Forum (SIF), under the auspices of the voluntary intergovernmental initiative, the Group on Earth Observations (GEO). The four-hour online workshop, held October 20, focused on the GEOSS Common Infrastructure and the GEOSS Data Management Principles and related interoperability challenges. During the workshop Downs gave the presentation, “Introduction to GEOSS Data Management Principle 5: Data Traceability,” providing an overview of the state-of-the-art in ensuring that both data providers and users are able to document and understand the lineage of data and all transformations applied to data.
