# Web Map Context Demo

How to use this demo:

- Drag to pan, use the mouse wheel to zoom in and out.

In this demo the Legato map client is configured by two files:

- config.xml determines how the map client should appear;
- viewContext.xml defines which map content should be displayed.

This example is functionally the same as the simple demo, but the map client configuration is now split into two files: look and feel is configured separately from the content, control is separated from the data.

The config.xml file configures a map viewer with a single navigation control which supports panning and zooming. This configuration also includes the `ExtendedWMCLoader` which loads layers from a separate viewContext.xml file. This is done after the map client is created using an additional AJAX request.

The file viewContext.xml is a Web Map Context specification of the map content. It describes which layers of which servers should be displayed by the map client as well as some general information such as size of the map client frame (the `Window` element) and the initial bounding box.

For more details on the configuration please see the files config.xml and viewContext.xml files.
