Overview

ArcGIS Online is a central, Web-based repository that gives you immediate access to ready-to-use content that is deeply integrated with ArcGIS. You can directly connect to maps, tasks, and Web Mapping APIs published by ESRI. You can also search for content published by other users and share your own maps, layers, and tools.

With ArcGIS Online, you can

• Access prepublished maps and reference layers; browse templates, user guides, and tutorials; and view metadata.
• Easily organize, find, and share geographic information to collaborate with other users who share a common interest.
• Develop Web applications quickly by leveraging ArcGIS Online map and task services and ArcGIS Web Mapping APIs.
• Jump-start your GIS projects without additional investments in infrastructure or staffing. ArcGIS Online is hosted by ESRI and powered by ArcGIS Server and ArcGIS Data Appliance, and new content is updated and added continually.
• Save money because you don't have to worry about software and data acquisition, management, and updates.
• Save time because you have access to ready-to-use content to build your applications.

Contribute your geographic data content. Let ESRI publish and host your authoritative content as part of a community basemap that ArcGIS users can access freely through ArcGIS Online map services. Learn more.
