A WebWorldWind client with an on-screen layer manager and server manager capable of rendering user-defined analytical layers.

This actor is a web-browser user.

This actor is a WorldWindServerKit (WWSK) GeoServer instance.

In this use case, the user manages the map/imagery layers that are shown on the globe.

In this use case, the user defines new WWSK connection or opens an existing connection.

In this use case, the user manages the server connections that provide maps and data to the client.

In this use case, the user defines an area-of-interest on the globe, i.e., a sector, which in turn defines the bounding box for subsequent coverage requests.

In this use case, the user makes a request for a WCS coverage which entails selecting an available coverage, defining the area-of-interest, and specifying the level of detail, plus any coverage specific parameters.  This request is sent to the server for processing.

In this use case, a WCS coverage is retrieved from the WWSK server or loaded from the persistent store.

In this use case, a coverage is rendered on the globe as an analytical layer(s), providing the user with the ability to control the color ramps and elevations of the coverage bands.
