CIESIN associate director for Information Technology Sri Vinay and senior digital archivist Robert Downs participated in several workshops and meetings in July, addressing different aspects of Earth science and geospatial data and software management. In early July, Downs traveled to Frascati, Italy, to participate in the workshop, “Advancing the Understanding and Measurement of the Societal Benefits of Earth Observations,” organized to advance the understanding and measurement of the societal benefits of Earth Observations. He served as rapporteur for the session, “Understanding the Context,” and presented briefings from that session during two roundtable sessions. The workshop was held July 1–3 at the European Space Agency (ESA) Centre for Earth Observation.

Later in the month, Vinay attended the workshop, “Conceptualizing a Geospatial Software Institute (GSI) Workshop 3: Strategic Plan and Governance of GSI,” held July 14–16 at the National Socio-Environmental Synthesis Center (SESYNC) and the Westin Hotel in Annapolis, Maryland. Funded by the U.S. National Science Foundation (NSF), the workshop aimed to first brainstorm and then draft a strategic plan for a GSI. Vinay was one of the discussion leads for the session, “What Services Should GSI Provide to Enable Broad and Impactful Scientific Advances?” which focused on challenges, opportunities, and strategies for achieving the plan’s first and fifth goals—to combine geospatial data and software at scale for scientists to harness the geospatial data revolution, and to advance high-performance geospatial software while making synergistic contributions to data-intensive and high-performance computing. Vinay, together with CIESIN director Robert Chen and associate director for Geospatial Applications Greg Yetman, provided a position paper, "Geospatial Software Governance from an Applied Research Perspective," as an input to the workshop.

During the same week in Tacoma, Washington, Downs attended three different meetings: the DataONE Users Group and Council of Data Facilities meetings on July 16, and the 2019 ESIP Summer meeting, July 16–19. He presented the poster, “Data Lifecycle Opportunities for Improving the Usability of Earth Science Data,” at the DataONE meeting. At the ESIP meeting, he gave the paper, “Socioeconomic Data Citations and Impact,” during the session, “Current Approaches for Tracking and Exposing Research Object Usage Metric,” and also presented the poster, “Understanding the Impact of Global Earth Science Data," during the poster session.

CIESIN staff joined more than 17,000 other geographic information system (GIS) experts at the annual Esri User Conference, held July 8–12 at the Convention Center in San Diego, California. The conference theme was “The Intelligent Nervous System,” emphasizing the fundamental role of GIS in supporting an organization’s capabilities. For the plenary, famed researchers and conservation activists Jane Goodall and E.O. Wilson spoke with Esri founder and CEO Jack Dangermond about the critical importance of preserving biodiversity and the work they are doing towards this goal. Deputy director Marc Levy, senior geographic information specialist Linda Pistolesi, and senior research assistants Matthew Heaton and Anela Layugan took part in the Sustainable World Showcase, highlighting the GRID3 program, which CIESIN coordinates. Geographic information specialists Olena Borkovska, John Squires, and Pistolesi presented a poster in the Map Gallery, describing the development of the Basic Demographic Characteristics data set of SEDAC′s Gridded Population of the World, version 4.11 (GPW4.11) data collection. Former GRID3 intern Haokai Zhao and colleagues from the Population and Development Branch of the United Nations Population Fund (UNFPA) also participated in the conference.

The NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN has recently released three global data sets that utilize satellite-based remote sensing data to help characterize critical aspects of human-environment interactions: Trends in Global Freshwater Availability from the Gravity Recovery and Climate Experiment (GRACE), v1 (2002 – 2016), Development Threat Index, v1 (2015), and Altimeter Corrected Elevations (ACE2), v2 (1994 – 2005).

The ability to measure trends in global freshwater availability has been made possible by NASA′s Gravity Recovery and Climate Experiment (GRACE). By measuring small changes in Earth′s gravity field, the GRACE mission was able to track key dynamics of the global water cycle at a spatial resolution of 0.5 degrees during the period from 2002 to 2016. Terrestrial water availability storage is the sum of groundwater, soil moisture, snow and ice, surface waters, and wet biomass, expressed as an equivalent height of water. The data are valuable in helping to evaluate and predict emerging threats to water and food security. Part of SEDAC's Satellite-Derived Environmental Indicators (SDEI) data collection, the data set was developed by researchers from the NASA Goddard Space Flight Center and Jet Propulsion Laboratory and from National Taiwan University.

The Development Threat Index, v1 seeks to map terrestrial global, future development threats resulting from agricultural expansion, urban expansion, and energy development (conventional oil and gas, unconventional oil and gas, coal, mining, biofuels, solar, and wind). Individual threat layers draw on several different data sets derived in part from satellite remote sensing data, including the Global Grid of Probabilities of Urban Expansion to 2030, the Global Roads Open Access Data Set (gROADS), and the Global Reservoir and Dam (GRanD) data sets, all available through SEDAC. The Index has been produced on a 50 square kilometer grid by a team from The Nature Conservancy, the University of Minnesota, and the University of British Columbia. It has been added to SEDAC′s Land Use and Land Cover (LULC) data collection, but shares similar objectives with the Human Footprint data also distributed by SEDAC (e.g., Human Footprint, 2018 Release).

The ACE2 data set is based on a Global Digital Elevation Model (GDEM) derived primarily from multi-mission Satellite Radar Altimetry in combination with data from the Shuttle Radar Topography Mission (SRTM). By using data from an altimeter, an instrument that uses radar to measure height, researchers were able to better assess ground elevation in areas with high tree cover. This represents an improvement over the original SRTM data, which only measured the top of the canopy. ACE2 is intended for research and applications such as flood risk assessment, landslide modelling, urban planning, and sea level rise impact assessment. In light of ongoing efforts to improve GDEMs, SEDAC has decided to preserve this version for future analysis and intercomparison as part of a new Digital Elevation Data Collection (DEDC). The data set was developed by a team from the UK and the European Space Agency.

CIESIN bids farewell to Kira Topik, senior research staff assistant, who has moved to the West Coast to pursue other opportunities. Topik began at CIESIN in the summer of 2017 as an intern while pursuing her MA in Columbia University’s Climate and Society program.

The User Working Group (UWG) of the NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN met in Washington DC June 6–7. The meeting was chaired for the first time by Barbara Ryan, former executive director of the Group on Earth Observations (GEO) and winner of the 2018 William T. Pecora Individual Award given by the U.S. Geological Survey. Nine UWG members participated in person, including new members Ryan and Navin Ramankutty of the University of British Columbia. Brian O'Neill of the University of Denver participated remotely in a breakout session. UWG member Dave Jones of StormCenter Communications gave an informal lunch talk, “Creating a Unified Response During Disasters by Sharing Trusted Data Across Platforms in Real-Time.″ The UWG received updates on SEDAC strategic priorities related to global-scale human population and settlement data and support for the 2030 Agenda for Sustainable Development. Potential new activities to archive and disseminate spatially explicit scenarios of Shared Socioeconomic Pathways (SSPs) and to update low-elevation coastal zone (LECZ) data were reviewed in detail, together with plans for expanding training on the integration of remote sensing and socioeconomic data. A new process for third-party submissions of data was also discussed.

The UWG meets in person once per year, typically either at Columbia University in New York City or in Washington DC. More than 10 representatives from NASA headquarters and the Goddard Space Flight Center participated in this year's meeting, including Nancy Searby of the NASA Applied Sciences Program, who has recently been appointed as SEDAC's program scientist. Three other NASA Distributed Active Archive Centers (DAACs) also sent observers. CIESIN participants included director Robert Chen, who serves as SEDAC manager; associate director for science applications Alex de Sherbinin, who serves as SEDAC deputy manager; and research scientist Susana Adamo, who serves as lead SEDAC project scientist.

A new digital game for players of any age, created by the New York Hall of Science (NYSCI) and Design I/O, uses theories of playful learning to encourage computational thinking and scientific inquiry. CIESIN was a partner in the project, supported by the U.S. National Science Foundation (NSF), that sought to develop innovative ways to teach kids about ecological concepts using approaches drawn from the computer sciences.

The interactive game, The Pack, takes place in a futuristic world called Algos, where food and water are scarce. The challenge of the game is to restore ecosystem balance. The player marshalls different creatures to perform a variety of tasks—digging, moving, holding, grabbing, seeking, and bumping—in order to move water around the environment and find seeds. By arranging and repeating tasks in different order, the player can develop, test, and modify new algorithms to achieve specific objectives.

The Pack is an “open world,” meaning players can explore and choose their objectives more freely than in a linear game with directed goals. As players continue in the game, they encounter increasingly complex opportunities to develop and use their algorithmic thinking skills. For young players, the game seeks to develop a problem-solving mindset and to strengthen social and strategic-thinking skills.

The game leverages increased awareness in the education field that children learn best through play, especially in science. The NYSCI is a pioneer of “design-make-play,” an approach that is central to all of NYSCI's exhibits and activities at its museum location in Queens, New York. Based on the two concepts, awareness of the environment and computational thinking, The Pack is meant for both informal and formal settings in support of Science, Technology, Engineering, Mathematics, and Computing (STEM+C) education.

The Pack was inspired by the award-winning Connected Worlds installation, which came out of a previous NSF-funded collaboration between NYSCI, Design I/O, and CIESIN. This immersive fantastical virtual world lets visitors playfully and tactilely interact with and explore the interdependence of different habitats within a larger ecosystem. The JPB Foundation supported the final production and release of both Connected Worlds and The Pack.

The Pack is free and available for download for Mac OSX, Windows, and iOS devices (iPhone, iPad, and iPod touch). The game is intended for children 4 years old and up. It currently has a rating of 4.8 out of 5 stars in Apple's App Store.

“Earth Observations for Impact” was the theme this year of the annual Group on Earth Observations (GEO) Symposium 2019, held at the World Meteorological Organization (WMO) headquarters in Geneva May 27–29. Robert Chen, CIESIN director, and Robert Downs, CIESIN senior digital archivist, participated in the Symposium, which brought together representatives from many different GEO member countries and participating organizations to plan the 2020–2022 GEO Work Programme. CIESIN is contributing to a number of GEO activities, including the Human Planet Initiative, which Chen co-chairs with Martino Pesaresi of the European Commission′s Joint Research Center, and Earth Observations for the Sustainable Development Goals (EO4SDG), which is co-chaired by NASA, the Japan Aerospace Exploration Agency (JAXA), and Mexico′s National Institute of Statistics and Geography (INEGI).

As part of Columbia University′s Data Science Day held April 3 at Lerner Hall in Manhattan, CIESIN intern Nanshan Li presented a poster on a project that aims to model population change using new sources of data such as wireless device location and night-time lights data. The poster was one of 36 selected for presentation at the event, which featured keynote speaker Brad Smith, president of Microsoft. The poster described initial analysis of test data available for Mexico, to see if such new data sources could help detect or monitor population change on short to medium time scales. Li is working towards her Master of Science degree in Data Science at Columbia. The poster was co-authored with Alex de Sherbinin, associate director for science applications; Kytt MacManus, CIESIN Senior Systems Programmer; Greg Yetman, associate director for geospatial applications; and Robert Chen, CIESIN director. The project is supported by a grant to the Data Science Institute from the Schmidt Futures Foundation.

The semi-annual plenary of the Research Data Alliance (RDA) drew nearly 500 research data experts to Philadelphia for a series of workshops and sessions under the theme, “With Data Comes Responsibility.” March 31–April 1 and April 4, CIESIN senior digital archivist Robert Downs participated in the RDA workshop, “International Network-of-Networks: Data Experts Workshop (iN2N),” aimed at producing a scientific white paper articulating the complexities of conducting research across international borders with a focus on data use and interoperability. The workshop was organized by Leslie McIntosh-Borrelli of Rensselaer Polytechnic Institute, with support from the U.S. National Science Foundation. CIESIN director Robert Chen also participated in a parallel workshop, “FAIR and Responsible Research Data Management.” Led by Jane Greenberg of Drexel University and Simon Hodson of the Committee on Data (CODATA) of the International Science Council (ISC), the workshop examined how the research data community could expand implementation of the FAIR principles—guidelines for making data findable, accessible, interoperable, and reusable. Chen gave a presentation, “Addressing FAIR through Legal Interoperability: Principles and Practice,” co-authored with Downs, reviewing the legal basis for developing open access data resources through the NASA Socioeconomic Data and Applications Center (SEDAC) operated by CIESIN.

Both Downs and Chen then participated in the 13th RDA Plenary April 2–4 at the Loews Hotel in Philadelphia. Chen led a discussion on the proposed revised charter for the RDA-CODATA Legal Interoperability Group, which he co-chairs. He also gave the presentation, “Global Fundamental Geospatial Data for Sustainable Development,” in a session on data for sustainable development goals and RDA connections. Downs summarized the work of the Data Granularity Task Force during the Data Discovery Paradigms Interest Group meeting, and co-led sessions on data versioning and on bringing data and computational infrastructures together to support open, reproducible research. Downs and Chen also presented the poster, “Exceeding Legacy Requirements to Meet New Requirements for Trustworthy Data Repositories,” co-authored with Alex de Sherbinin, CIESIN associate director for Science Applications. SEDAC has undergone certification by the ISC World Data System as a trustworthy data repository, to become one of more than 110 member organizations, in the category of Regular Member.
