Use Cases

Back To: Main Page

Overview

Construction of the Earth Information Exchange will be driven by users of the Federation products and services as described in our Federation Documents. The result will follow a component-based architecture.

The first stage in this process is to establish a few of the user's "wish lists" by capturing scenarios of use that they envision. We have divided these use cases into two sections, one showing use of the Exchange to address areas of societal need, and the other showing the interface and underlying components.

Use Case Discussion

Applications Use Cases

It will be the scenarios that are created by each cluster that will drive resource allocations. This page provides a point of access for the Use Cases under development by the ESDS Technology Infusion Working Group in support of ESIP Federation application area technology activities. Use cases of known data access and/or data production activities are needed to identify web services and chaining scenarios for future implementation. And may also provide reference use cases for the development of capabilities within the Earth Information Exchange or other Federation activities including proposals developed by Federation members.
