Changing the data sources for map layers

Data sources can be associated with several components in several ESRI mapping and charting solutions. In addition to feature layers, data sources can be defined for Reviewer checks and map series. All of these need a geodatabase that can be referenced as a data source, which can be a feature class in a personal, file, or enterprise geodatabase.

Properties for each item include the following:

• Type—The type of item that is using the data source reference
• Display Name—The name of the feature class being referenced as it is displayed in the table of contents or the Reviewer check
• Version—The database version being referenced
• Name—The name of the feature class being referenced, which includes the full path if you are using an enterprise geodatabase
• Unqualified Name—The name of the feature class
• Workspace Path—The full path to the current workspace being referenced

In terms of personal and file geodatabases, you can change the workspace associated with all the items listed in the Set Data Source dialog box or only one of them. For example, if you are missing a data source for a layer, you can associate it with any geodatabase or dataset that contains it, even if it is not the same as the others.

注意:

To change the data sources for all the items listed in the Set Data Source dialog box, the Show "Change Data Source" warning check box needs to be checked. If it is not checked, the data source is only changed for the selected layer. By default, the option is checked so you can choose whether to change the data source for all layers or only one.

步骤:

1. Start ArcMap.
   提示:

   If the ArcMap - Getting Started dialog box appears, you can open a new or existing map document. You can also check the Do not show this dialog box in the future check box and click Open.

2. If necessary, load data in the map.
3. Add the Set Data Source tool by doing the following:
   1. On the main menu, click Customize > Customize Mode.

      The Customize dialog box appears.

   2. Click the Commands tab.
   3. In the Categories list, click Production Framework.
   4. Click and drag the Set Data Source button to a toolbar.
   5. Click Close.
4. Click the Set Data Source button .

   The Set Data Source dialog box appears.

   

5. Optionally, click the Sources drop-down arrow and choose the source type for which you want to change the data source.
6. Optionally, to view only invalid data sources, check the Show Invalid Data Sources Only check box.

   This removes any of the valid data sources from the list on the Set Data Sources dialog box.

7. Choose an item in the Paths table.
8. If you do not want to change the data source for multiple sources, uncheck the Show "Change Data Source" warning check box.

   Only the layer you choose will have its data source changed.

9. Click Change Data Source.

   The Select Data Source dialog box appears.

10. Navigate to the feature class you want to associate with the item you selected.
11. Click OK.

    The Choose Repair Option dialog box appears.

    注意:

    This dialog box appears only if the Show "Change Data Source" warning check box is checked. If it is not, the path is updated after you click OK in step 11.

    
12. Choose an option for updating the data source.
    • If you want to update all the sources that have the same path as the data source you are updating, choose the Apply to all matching Paths option.

      For example, if you have tables and feature classes that are in the same workspace, the paths will be updated for both.

    • If you want to update all the sources for all the data sources that match the type you chose on the Sources drop-down list, choose the Apply to all matching Types option.

      For example, if you choose Tables in the Sources drop-down list, only the paths for tables listed on the Set Data Source dialog box are updated. Feature classes that are also listed would not have their paths changed.

    • If you only want to update the path for the data source you chose in step 7, choose the Apply to selected Item only option.
13. Click OK.
14. Click OK to close the Set Data Source dialog box.
