ArcGIS Online has a new map viewer. The new Map Viewer (formerly known as Map Viewer Beta) and Map Viewer Classic (formerly known as Map Viewer) are both available for students, faculty, and staff at no additional charge. Because the map viewers are built using different versions of the ArcGIS API for JavaScript, and some workflows are not yet available in the new Map Viewer, this functionality guide can help you find the best viewer for your specific needs. Upon opening the mapping platform ArcGIS Online, you can toggle between Map Viewer Classic and the new Map Viewer using the tools on the top ribbon.
