Figure 2.1 Text Description

At the top is a drawing of a computer with the label: Web client applications. The computer image extends into a little cloud with the label: External Internet.

A line extends from the bottom of this cloud into a wide oval diagram with the label: Internal network. The line leads to the drawing of a Web server and then, below the Web server, to a Geospatial server. The line then branches to drawings of a file server (left) and a database server (right). To the left (within the Internal network oval) is another computer drawing with the label: Administrators and internal client applications.
