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.
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.
