EARTH SCIENCE SERVICES > WEB SERVICES > DATA APPLICATION SERVICES
Services that are designed to support Clients, especially thin client software such as web browsers.

The services in the Application Services tier are used by Clients, and can use other services in the Application Services, Processing Services, and Information Management Services tiers.
