The Arctic Ocean Basemap
Over the past few years, Esri’s Ocean Basemap team has noted the world’s scientific attention shifting north. The receding sea ice and increased vessel traffic within the Arctic Ocean is coming front and center in discussions within the marine and maritime communities. To support the communities, Esri’s Ocean Basemap team developed the Arctic Ocean Basemap.
The Arctic Ocean Basemap (left) uses a special projection that is optimized for study of this region covering the northern latitudes of the globe from 90 to 50 degrees north. This (and the companion imagery version) is designed to be used as a basemap for overlaying other data for the Arctic region, such as this example (right) featuring sea ice extent and oil exploration data on top of the polar basemap.

In Sweden, Kalmar County Museum archaeologists Nicholas Nilsson and Fredrik Gunnarsson used Esri technology to unearth a moment frozen in time. Using data captured by a drone, a web app, and a dog with a keen sense of smell, the archaeologists mapped a fort and its houses as well as the violent fate of the people who lived there.
In the 5th century AD during Europe’s turbulent Migration Period, on the island of Öland off the coast of Sweden many ring forts were constructed, mainly as a places of refuge during times of war. Many gold artifacts have been found on the island, including gold coins given to islanders for serving as mercenaries in the Roman army. The area surrounding the Sandby Borg ring fort had an unusually high concentration of these gold coins.

The U.S. Environmental Protection Agency (EPA), responsible for protecting human health and the environment, has enabled 15,000+ staff members access to mapping tools. With this technology, EPA workers can create maps right from the data they have stored in Microsoft Excel. These maps serve as powerful tools for communication that can be shared with colleagues and embedded Microsoft PowerPoint presentations.
“Imagine if you could take a spreadsheet that contains a list of Brownfield sites and their street addresses and with the click of a button, turn it into an interactive map that could be used in reports, presentations and websites. ArcGIS Maps for Office enables users to take geographical data from an Excel spreadsheet and create a map to more easily communicate the message behind data.” - Ann Dunkin, Chief Information Officer

We are living in an exciting age for GIS and cartography, with maps being used in new ways, to solve new kinds of problems, and across the technology spectrum. To celebrate the ubiquitous nature of maps, Esri User Conference (Esri UC) attendees are invited each year to share their work in GIS and cartography. Hundreds of Esri users display their very best mapping efforts in the Map Gallery at the Esri UC during the week and it represents a remarkable collection of work.
This year, nearly 700 maps were submitted for the Map Gallery. A select number of qualified Esri judges are privileged to evaluate and assess these entries each year.
Using GIS to Build a More Data-Driven, Rehabilitative Criminal Justice System
Over 150 elected officials, law enforcers, and public health professionals from 67 communities across the country met in Washington, DC, last month to explore ways to keep low-risk offenders out of the criminal justice system and respond to the White House’s call for more informed justice.
The Numbers Speak
The urgency of the call is justified. According to the Bureau of Justice Statistics’ most recent data, more than two-thirds of offenders return to prison after three years, while three quarters return within five years. That rate of recidivism costs society by failing to rehabilitate people in the criminal justice system when it’s possible—and ultimately cost effective—to do so.
Your world is full of data, and maps help you to make sense of it. There is a growing need to turn geographic data into compelling maps. All users want to create beautiful, interactive maps and infographics with live data, easily and with confidence. The smart mapping mission is to provide a new kind of strong “cartographic artificial intelligence” that enables virtually anyone to visually analyze, create, and share professional quality maps in just a few minutes, with minimal mapping knowledge or software skills.
Smart mapping is designed to give ArcGIS users the confidence and ability to quickly make maps that are visually pleasing and effective. Cartographic expertise is “baked” into ArcGIS, meaning it is part of the fundamental user experience of using ArcGIS. The map results that you see in front of you are driven by the nature of the data itself, the kind of map you want to create, and the kind of story you want to tell.
The best thematic maps apply thoughtful analysis of the underlying data to a set of map parameters designed to bring focus and clarity to the topic. Here, the author has positioned the handles controlling symbol size (running beside the histogram) to emphasize areas with household incomes over $100,000. Great maps relate the data back to the real world, using visual cues that immediately highlight the message you want to convey.
Scientists Gather to Discuss the Impact of GIS in Future and Present Challenges
Esri has always embraced the intellectual domain. So when it became evident that User Conference attendees beyond traditional geographers and GIScientists could benefit from domain science targeted discussions, ideas for a special event began to form. Further deliberation produced a theme for the event — Advancing Science through GIS: Today’s Challenges and Preparing for the Future — and the foundation for Esri’s inaugural Science Symposium was laid.
Esri Chief Scientist Dawn Wright served as the Science Symposium’s organizer.

The Esri water team will be on site at the AWRA Summer Specialty Conference, July 11-13 at the Hilton Sacramento Arden West. The focus of this year’s event is the role of GIS to support better decisions across water, land, and ecological resources.
Esri is a bronze-level sponsor and exhibitor at the conference, where a spectrum of topics will be covered in 37 sessions over the course of three days, ranging from water resource data development techniques to complex computer modeling infrastructures.
GIS technology is both intuitive and cognitive. It combines powerful visualization and mapping with strong analytic and modeling tools. Remotely sensed earth observation—generally referred to in GIS circles simply as imagery—is the definitive visual reference at the heart of GIS. It provides the key—the geographic Rosetta stone that unlocks the mysteries of how the planet operates and brings it to life. When we see photos of Earth taken from above, we understand immediately what GIS is all about.
The story of imagery as an earth observation tool begins with photography, and in the early part of the twentieth century, photography underwent extraordinary changes and social adoption. Photos not only offered humanity a new, accessible kind of visual representation—they also offered a change in perspective. The use of color photography grew. Motion pictures and television evolved into what we know today. And humans took to the sky flying in airplanes, which, for the first time, enabled us to take pictures of the earth from above. It was a time of transformation in mapping and observation, providing an entirely new way of seeing the world.
World War II: Reconnaissance and intelligence gathering
During World War II, major advances in the use of imagery for intelligence were developed. The Allied Forces began to use offset photographs of the same area of interest, combining them to generate stereo photo pairs for enhancing their intelligence gathering activities. In one of many intelligence exercises called Operation Crossbow, pilots flying in planes—modified so heavily for photo gathering that there was no room for weapons—captured thousands of photographs over enemy-held territory. These resulting collections required interpretation and analysis of hundreds of thousands of stereo-photographic pairs by intelligence analysts.
Stereoscopic imagery was instrumental in identifying the facilities of Nazi rocket programs. This photo shows stereo glasses used for viewing offset photo pairs.

On Saturday, July 9 Esri is sponsoring Maps Camp at the United Nations in New York City. Esri’s Courtney Claessens will be speaking on two panels, “Philosophies of Open Source” and “What’s next for Open Source and Mapping.”
