Inaugural Esri Science Symposium Crystallizes Community

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.

Updated Map Features Global Ecology in Unprecedented Detail

In 2014, the US Geological Survey (USGS) and Esri announced the publication of the most detailed global ecological land units(ELUs) map in the world. The ELUs are terrestrial ecosystems defined and modeled as unique combinations of bioclimate, landform, geology, and land cover.

In creating the original version, the team learned of the input data’s limitations and created a plan to improve the ELUs with updated input data in 2015. Today, Esri and USGS are pleased to announce the availability of an update to the global ecological land units (ELUs) map.

In particular, Esri created a new global landforms layer to address valid criticisms of the earlier version, which under-represented hills and over represented plains. Additionally, the new landforms dataset gained more classes, including tablelands. The new dataset is also more regionalized, or less fragmented than the earlier dataset, and therefore more intuitive.

Highlighted is a portion of the Kaibab Plateau on the north side of the Grand Canyon in the U.S. New landform classes such as tablelands were incorporated into the 2015 Ecological Land Units dataset. Click on the image to open the EcoExplorer App to learn more about Ecological Land Units where you live.
