ArcGIS Online is a cloud-based, collaborative workspace for making interactive maps, sharing data that you create, and performing spatial analyses. Users can create maps, scenes, and web apps, analyze data, and share their creations with other members of UMass or the wider public. Users also have access to ArcGIS Living Atlas of the World (a wide ranging source of maps, apps, and data layers that users can bring into their own projects).
