What Are the System Requirements for Map Views?

13-6 System Administrators Guide for Oracle Business Intelligence Enterprise Edition Figure 13–3 Edit Background Map Dialog with Intersection The layer ordering at zoom level 4 is unclear, because multiple layers can be shown. Because of the layer order that is specified in the Interactive BI Layers section of the dialog, the map renders with the following order at zoom level 4: Country, City, and State reading from bottom to top, which is incorrect. To correct this problem, you must ensure that layers are always ordered properly in the dialog. You can re-order layers by clicking the Move Down and Move Up buttons on the zoom grid of the dialog, or by clicking the Sort Layers by Zoom Level button. For example, you can click the Sort Layers button in the dialog to specify that the layer ordering at zoom level 4 is Country, State, and City. See Oracle Fusion Middleware Users Guide for Oracle Business Intelligence Enterprise Edition for more information about layers.

13.3.1.3 Changes to Spatial Metadata Require Restart

Administrators can edit the spatial metadata that is stored in the Oracle Database and accessed by MapViewer. For example, an administrator can add a new layer. These edits are not visible on the Oracle BI Presentation Services Administration pages for managing maps until MapViewer is restarted and so refreshed with the latest updates.

13.3.2 Administration Page Functions

The Oracle BI Presentation Services Administration page provides the Manage Map Data link. This link displays the Manage Map Data page, where you can manage the logical and display versions of the data from various physical data sources. This defines the layers that content designers use when creating map views. The data that is available for managing maps and data is stored in Oracle Database as part of MapViewer. Using this page, you provide: ■ Logical names to prevent any existing BI column mappings and map analyses from breaking because of changes to the physical data or to the data source. ■ Display names so that the geographic data is meaningful to end users.

13.3.3 Administering Maps Using Administration Pages

This section assumes that you installed Oracle BI Enterprise Edition and that Oracle MapViewer was automatically configured and deployed. For information on MapViewer, see Oracle Fusion Middleware Users Guide for Oracle MapViewer. To administer maps using Administration pages: 1. Sign in to Oracle Business Intelligence.

2. In the global header, click Administration.

3. Click the Manage Map Data link to display the Manage Map Data page.

4. Click the Layers tab.

5. Click the Import Layers button to display the Import Layers dialog.

6. In the dialog, select the connection and the layers that are needed for zooming and

drilling. This tab is not prepopulated by other selections on the Administration pages. You can use any layers or images with any map. Click OK when you have finished selecting layers that are appropriate for the subject area with which you are working.

7. Back on the Layers tab, select a layer, then click the Edit Layer button to display

the Edit Layer dialog in which you associate layers with attribute columns so that you can display BI data in the map view. Click OK when you have finished editing the layer. You use this tab to associate layers with BI data. If you use the City column in multiple subject areas, then you must associate it with a layer for each subject area.

8. Click the Background Maps tab, then click the Import Background Maps button

to display the Import Background Maps dialog.

9. In the dialog, select the connection and the main maps to use.

The connection that you select for the main map can be different from the connection for the layers or images. Click OK when you have finished selecting main maps. 10. Back on the Background Maps tab, select a map, then click the Edit Background Map button to display the Edit Background Map dialog in which you name the map and specify the order of layers and their zoom levels. Click OK when you have finished editing the map. 11. Optionally, click the Images tab, then click the Import Images button to display the Import Images dialog. You can import images if you plan to use them as a format on maps. 12. In the dialog, select the connection and the images to use. Click OK when you have finished selecting images. 13. Click OK when you have finished working with the Administration page. After you have specified background maps, layers, and the associations between BI columns and spatial columns, MapViewer creates a static image for a map using this information and sends that image for rendering in the browser for use by content designers and end users in map views. 13-8 System Administrators Guide for Oracle Business Intelligence Enterprise Edition

13.3.4 Handling the Translation of Layers in Maps

You can use the functionality of MapViewer to label the features of a theme called a layer for maps in Oracle BI EE using a specific language or locale. To configure these translated labels for maps, use the information that is provided in Oracle Fusion Middleware Users Guide for Oracle MapViewer.
