Abstract

Global Terrestrial and Marine Ecosystems - The GEO Approach
Track: National Mapping
Authors: Roger Sayre, Sean Breyer, Dawn Wright

The Group on Earth Observations (GEO) is a consortium of nations working together to advance the use of earth observations for problem solving. Recognizing the importance of an ecosystems geography perspective for planning sustainable development, GEO commissioned the development of detailed, standardized maps of global ecosystems. We (USGS and Esri) present an overview of progress to date in mapping global ecological land units (ELUs) and ecological marine units (EMUs).
