ArcAtlas: Our Earth is a unique digital atlas, the result of many years of research by geographers and other earth scientists from Russia and the United States. More than forty different geographic themes were compiled for this atlas, with much of the information developed especially for this project.
The collaboration involved the efforts of more than 120 scientists and specialists belonging to a dozen research and other institutions including DATA + (Russia), the Institute of Geography of the Russian Academy of Sciences, M.V. Lomonosov Moscow State University, and ESRI (United States).
