Exciting news from the Arctic! Version 2 of the Arctic DEM has been released. Topographic elevation of the Arctic can now be viewed and analyzed like never before. This release extends the detailed 2 meter Alaska elevation data with additional 2m data for Novaya Zemlya and Franz Josef Land, as well as preliminary 8 meter data for the entire Arctic. Additional detailed 2 meter elevation data will be released in quarterly installments over 2017 until the arctic data is complete. This is the result of a partnership between Esri, the National Geospatial Intelligence Agency, the National Science Foundation, and the Polar Geospatial Center at the University of Minnesota.
In September 2016, the White House hosted an Arctic Ministerial meeting, with over 20 countries represented, where this data was showcased and new commitments on data provisions were sought. The goal of the meeting and the function of the new data is to help people better understand, adapt to, and address the changing conditions in the Arctic.
The four key themes include:
- Understanding Arctic-Science Challenges and their Regional and Global Implications.
- Strengthening and Integrating Arctic Observations and Data Sharing.
- Applying Expanded Scientific Understanding of the Arctic to Build Regional Resilience and Shape Global Responses.
- Using Arctic Science as a Vehicle for Science, Technology, Engineering, and Math (STEM) Education and Citizen Empowerment.
Putting remotely sensed image data to work
Imagery provides more than just plain pictures. Some sensors detect energy beyond what is humanly visible, allowing us to “see” across broad swaths of the electromagnetic spectrum. This enables scientists, geologists, farmers, botanists, and other specialists to examine conditions, events, and activities that would otherwise be hidden. The implications are profound and the applications are seemingly endless.
Expanding your point of view
Every day, the earth is directly imaged from scores of sensors in the sky and from orbit in space. Almost everything that happens is measured, monitored, photographed, and explored by thousands of imaging devices mounted on satellites, aircraft, drones, and robots. Much of this information ends up as imagery that is integrated into a large living, virtual GIS of the world, deployed on the web.
Some of these sensors see beyond what our eyes see, enabling us to view what’s not apparent. Multispectral imagery measures and captures this information about a world that has many more dimensions than just the colors of the rainbow—it sees past the limits of what our eyes perceive.

Over 60% of the Earth’s surface has not yet been mapped. The ocean covers 70% of our planet’s landmass, and of that, less than 15% of the sea floor has been mapped at a resolution greater than 5 km. In fact, we have higher resolution maps of the entire surface of the Moon, Venus, and Mars than we do of our own Earth. But this situation can be changed. We are in the midst of a Technological Revolution and with the advent of exponential technologies such as 3D printing, Robotics, Artificial Intelligence, and Virtual Reality, we now have smaller and cheaper tools and greater access to information.
Mapping the sea floor has, historically, been a challenge. Seawater is obviously opaque, which prevents us from using visible, remote surveying techniques to get maps of the sea floor. Seawater is a harsh and corrosive medium and, with a viscosity greater than air, it has additional engineering challenges such as high friction resulting in rapid power drain for any device that is used to map the bathymetry underwater. It is also expensive to access because the technology of today requires ships to sail to the area being mapped before the mapping technology is deployed. At an average cost of $60,000 a day, it can easily cost a few hundred thousand dollars before mapping can even begin.
The Shell Ocean Discovery XPRIZE, a 3-year competition launched last December, is incentivizing innovators to develop the autonomous underwater robots we need to map the sea floor at 5m or higher resolution and take high-definition images of the deep sea. Within this is a $1 million National Oceanic and Atmospheric Administration (NOAA) Bonus Prize, for teams who can develop an underwater tracking device that can autonomously track a biological or chemical to its source. The devices will be shore-based or aerial deployments, removing the massive costs associated with ships. The competition will conclude in December 2018 and, like all other XPRIZE competitions, there will be a number of technical solutions that emerge to provide underwater cartographers the tools they need to survey the sea floor.
Visitors to Esri often pause for pictures beside an ivy-covered wall emblazoned with the word GEOGRAPHY in raised metal letters. The inscription speaks to an ingrained belief that geography offers a unique framework for organizing the world’s knowledge in a way that fosters better decision-making and a more sustainable future. Consistent with this belief, the education outreach team I lead at Esri does what we can to nurture geographic thinking and methods across the spectrum of academic disciplines.
That’s a big job. Disciplines have proliferated since the advent of the modern university in the 19th and 20th centuries. Consider this concept map of contemporary academic disciplines. Few disciplines depicted explicitly recognize geography, let alone GIS, as an integral way of understanding the world. Given the longstanding claim that a science of geographic information undergirds GIS (Goodchild 1992), you might suppose that Information Science is one of the disciplines that’s likely to appreciate the special properties of spatial data. If so, you’d be surprised to find that there’s precious little “G” is IS.

The World’s Largest Lesson
World leaders from all nations, developed and developing, have committed to the Global Goals for Sustainable Development. Seventeen truly ambitious goals, and at Esri, we are committed to achieving each one.
In partnership with Project Everyone, we are incredibly excited to collaborate on the World’s Largest Lesson and their Focus on Goal 5, Gender Equality. Using the content in these lesson plans, teachers around the world are able to reach out to a new generation and help them stand up and embrace their part.
Achieving Gender Equality is ambitious, to be sure, and perhaps the first step is to know where you stand. Get to know those who are in important roles, starting in your own community and all the way up to your national representatives.
Esri Joins ASPRS UAS Mapping Symposium as Keynote Speaker and Exhibitor ― Sharing How Drones are Changing the Face of Remote Sensing
The annual UAS Mapping Symposium is one of the nation’s leading conferences on drones, bringing together geospatial experts from across the country. The symposium is organized by the American Society of Photogrammetry and Remote Sensing, the premier imaging and geospatial information society.
As the world’s leading provider of GIS technology worldwide, my Esri colleagues and I are pleased to join ASPRS for this special opportunity to educate and inspire UAS industry professionals. My keynote session, “The Illusion of Simplicity: The Case for Making Drones Easy to Use”, will explore gaining the geospatial advantage by solving application-specific problems using imagery-derived information from UAS systems. I will share recent examples illustrating several use cases, along with observations on near-term trends related to drone use within GIS systems.
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.

Esri is getting the word out about an exciting opportunity to create dynamic data solutions for the Department of Education’s Asian American and Pacific Islanders (AAPI) Data Challenge.
We are challenging people to unleash the power of data by way of their own geographic analyses, visualizations, predictive models and more – to tell a compelling story. We believe new ways of exploring and boosting the visibility and utilization of data on AAPIs – helping to make it more meaningful – will inspire better understanding, insight, and action.
The challenge was announced by the White House Initiative on Asian Americans and Pacific Islanders (WHIAAPI), and AAPIData.com, a research project sponsored by the University of California, Riverside. The initiative’s aim is to improve the quality of life for Asian Americans and Pacific Islanders across the nation through increased access to, and participation in, federal programs.
In the US, drug overdose is the leading cause of accidental death, with opioid addiction driving the epidemic. Opioids include both legal drugs, used for pain relief, and illegal drugs like heroin. These drugs are highly addictive, and anyone from any walk of life can become dependent on them. In 2014, more than 29,000 opioid related deaths occurred in the US.
Monday, August 29 marks the 11 year anniversary of Hurricane Katrina, the costliest disaster in American history. And while the category five storm caused unprecedented damage, the community has rebuilt the destroyed infrastructure, and has also taken new steps forward technologically.
The city of New Orleans now uses GIS extensively, and incorporates Esri’s ArcGIS platform into a series of enterprise applications. These help the public stay informed as well as enabling them to participate in making their city a better, safer place to live.
For instance, a new website called Where Y’at, is allowing citizens to access public data as easily as any common search engine. By typing in their address, people can find up-to-date information about property boundaries, garbage, and recycling pick-up days, polling locations, district representation, and more.
