Every year, works of mapmakers from around the world are selected for the Esri Map Book to demonstrate how geographic information system (GIS) technology helps our governments, businesses, and citizens. Esri Map Book, Volume 33 continues this tradition, showcasing maps and applications that use ArcGIS to evaluate the sustainability of resources, determine efficient transportation routes, mitigate the effects of natural disasters, and much more. Each map or application includes a description of its purpose and how it was produced. Esri Map Book, Volume 33 is an important collection of maps for GIS users, cartographers, collectors, and map libraries.
