The customization consists of defining the topologic objects that will be linked to data, the formats specific to various areas, and their dimensions and positions.
If a geographical schema is embedded into a spreadsheet document, you can import a Geographical schema document from the disk using the Read command from the property palette.
To clear a geographical schema, use the Clear link.
To manage layers of a geographical schema, use the Settings link. This opens the layer settings window.

Use the toolbar buttons to add, edit, and delete layers.
When you add a layer, a layer selection dialog box opens first, and then a layer import options window (in the figure).
In the window, specify the layer name to be displayed in the schema, the data series to be imported, and data series names and display types.
Each topological object on a geographical schema has a Value property. It stores free-form data that can be used to identify an object.
In the Layer import options window, each object value is filled with some data series value. To import values, select the Fill the "Value" property of layer objects check box and specify the source series.
Once you have selected the layers, you can customize them.
