Use Cases

Back To: Main Page

Overview

Requirements for the Earth Information Exchange will be established by users. The first stage in this process is to establish user's "wish lists" by capturing scenarios of use in plain language as described by the users themselves. In the next stage, domain experts expand this description into a more formal Use Case description that will drive the development of the Exchange.

We are developing two types of use cases: one addressing areas of societal need, and the other showing the interface and underlying components that might be applied to address this need.

Use Case Discussion

Earth Science Solutions Use Cases

Scenarios that capture opportunities to apply Earth science for public benefit will drive resource allocations. For example, this page provides a point of access for the Use Cases under development by NASA's 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.
