Use Cases

Overview

We have divided the use cases into several sections basically following the sections of the Federal Enterprise Architecture.

Figure 1. Federal Enterprise Architecture Reference Models

Eventually, it might be useful to construct the ESIP exchange using a collection of interrelated "reference models" as employed by the US Government in the Federal Enterprise Architecture.

The most important aspects of our development strategy are shown on the left and right of Figure 1. Construction will be driven by the "business" of the Federation as described in our Federation Documents. The result will follow a component-based architecture.

The Use Cases for the Earth Information Exchange are accessible from here.
