ArcGIS is a system that lets you easily author data, maps, globes, and models on the desktop and serve them out for use on a desktop, in a browser, or in the field via mobile devices, depending on the needs of your organization. Server GIS gives you the ability to create, manage, and distribute GIS services over the Web to support desktop, mobile and Web mapping applications.
