Why Use the Web Mapping APIs

The Web Mapping APIs allow you to develop rich, interactive applications using JavaScript, Flex, or Silverlight. You can embed your applications in Web pages or launch stand-alone Web applications from any Web page (like the one shown to the right).

You can

• Add content to the map via online services.
• Add your own tools and widgets.
• Build stand-alone applications.
• Add GeoRSS feeds and other Web content.
• Connect to GIS servers.

Development with the APIs is free. Deployment is also free under certain conditions. Find out more about pricing.
