# Assign geographic properties

Analyzer lets you visualize data on a geographic map. For common geography types, such as country, state, city, or postal code, the Data Source Wizard automatically populates geographic parent-dimensions and subsequent child-levels to use in Analyzer.

To refine the use of **Geography Map** visualizations in Analyzer, you can associate custom data fields with a particular geography type. After you identify the fields that represent a geography type, you can use Analyzer to visualize this geographic information on a map.

These steps show you how to assign geographic properties to a level with the User Console.

1. Within the Data Source Model Editor, click the **Analysis** tab.
2. Select each of the geographical levels individually and assign each level a **Geography Type** in the **Properties** pane.

   This classifies the data with the correct geography type.

The geography type is now defined for that level.
