Esri’s new Global Content Challenge contest, engaging students all over the world, is proud to announce the winners! With the power of Esri content at their disposal, students told their own compelling scientific stories using the Esri Story Map Journal app. Entrants used their own geographic analyses, visualizations, predictive models, and more to explore a variety of scientific themes.
The contest was open from August to November and Esri was happy to receive ~550 registrations from students in nearly 60 countries, with 70 actual submissions. A distinguished international panel of judges chose projects that best exemplified the spirit of the contest: unleashing the power of Esri’s Living Atlas of the World content.

A newly developed International Digital Elevation Model Service (IDEMS) is now available under the umbrella of the International Gravity Field Service (IGFS) of the International Association of Geodesy (IAG). IDEMS provides a focus for distribution of data and information about various digital elevation models, including spherical-harmonic models of Earth’s global topography and lunar and planetary DEM. Related datasets, such as representation of Inland Water within Digital Elevation Models, and relevant software which are available in the public domain are also provided. IDEMS will provide the following DEM related products:
- Compilation, tutorial-style provision and maintenance of information on global gridded DEMs
- Compilation of available national elevation data sets with information on data resolution, methods used for DEM generation and links to providers
- Generation and dissemination of spherical-harmonic models of Earth’s global topography and bathymetry
- Compilation of geodesy-relevant DEM-studies
- Extension of the focus from Earth to Moon and terrestrial planets through compilation of information on available planetary topography models
IDEMS is hosted and operated by Esri, lead by myself and Dr Jianbin Duan (Deputy Director). The new IDEMS website is available at: https://idems.maps.arcgis.com/home/index.html.
Last week President Obama hosted the first-ever White House Frontiers Conference in Pittsburgh, an event co-hosted by the University of Pittsburgh and Carnegie Mellon University. Esri was among many of America’s leading innovators invited to come together to discuss how … Continue reading
The Arctic environment is a leading indicator of climate change. The shifts that will eventually affect the entire globe are among the most visible there. A comprehensive understanding of the shifts occurring in this area are crucial now more than ever.
Traditional imagery of the Arctic was collected via aircraft, but is very limited due to the inhospitable and remote nature of the polar region. Now 3-D digital elevation models (DEMs) of the entire Arctic are scheduled for release by 2017. With a resolution of 2 m, these new DEMs are over one hundred times higher resolution than what has previously been available for the entire Arctic. This has been made possible through a unique public private partnership between Esri, the White House and several important partners by way of DigitalGlobe satellite imagery.
Today the first of these rich elevation models covering the State of Alaska is being released. They are the first deliverable of the ArcticDEM project, created after a January 2015 Presidential Executive Order calling for enhanced coordination of national efforts in the Arctic. Climate Change is one of the biggest threats we face, it is being driven by human activity, and it is disrupting Americans’ lives right now. President Barack Obama spoke about the project at an Arctic conference in Kotzebue, Alaska on September 3, 2015 and called for action to reverse the trend of climate change, an exponentially growing problem for the entire planet.

Recent innovations in information, analyses, and science-policy linkages can help guide the planet towards a more resilient future.
For many of us when we think about the ocean, it’s a situation of “out of sight, out of mind.” In our limited awareness of the ocean, we see only the surface and think only of vast expanses of lifeless water, not realizing all of the complexities at play.
In fact, the ocean provides over HALF of the oxygen that we breathe. It regulates ALL of our weather patterns, it feeds us, and it provides for our energy and economy.
The ocean is a champion at absorbing human-derived (anthropogenic) CO2. Around half of all carbon dioxide produced by humans since the industrial revolution has dissolved into the world’s oceans. Coastal habitats store five times more carbon than do inland tropical forests. This has all helped to slow global warming.
So in reality, the ocean is vital to all of us, no matter WHERE we live. Continue reading
“We, the people, still believe that our obligations as Americans are not just to ourselves, but to all posterity. We will respond to the threat of climate change, knowing that the failure to do so would betray our children and future generations. Some may still deny the overwhelming judgment of science, but none can avoid the devastating impact of raging fires, and crippling drought, and more powerful storms.”
Thus spoke President Barack Obama in his 2nd inaugural address, to the delight of many, if not most in the scientific community. Indeed, there are many societal problems across the world that increasingly revolve around science. These include pollution and waste management, pandemics and biosecurity, access to clean air and clean drinking water, response to and recovery from natural disasters, choices among energy resources (oil and gas versus nuclear versus “alternative”), and the loss of open space in urban areas, as well as biodiversity in rural areas. And yet, there is a tension between the world of science, which is focused on discovery, and the world of policy making, which is focused on decisions.
Climate Change Is a Geographic Problem
Reducing the risks caused by climate change is an immense challenge. Scientists, policy makers, developers, engineers, and many others have used GIS to better understand a complex situation and offer some tangible solutions. Technology offers a means to assess, plan, and implement sustainable programs that can affect us 10, 20, and 100 years into the future. Continue reading
