Esri and the United States Geological Survey (USGS) are pleased to announce the development of the highest-spatial-resolution ecological land units (ELUs) map of the world "ever produced."

The Global ELUs map portrays a systematic division and classification of ecological and physiographic information about land surface features. The work was commissioned by the intergovernmental Group on Earth Observations (GEO), and published in print by the Association of American Geographers (AAG).
