Configuring the spatial reference for the scratch database

此主题仅适用于 ArcEditor 和 ArcInfo。

The Feature Builder window has several properties that can be customized on the General pane on the Feature Builder Settings dialog box including the precision of coordinates, the function library to use, snapping, and the spatial reference extent. The Spatial Reference category contains an option that allows you to define the spatial reference of the scratch dataset. This includes the coordinate system, spatial domains, and the precision.

警告:

If you change the spatial reference of the scratch layers while they are added in the table of contents in an ArcMap session, you should remove the layers with the previous spatial reference and add the layers with the new one using the Add Scratch Data Layers tool tool on the Feature Builder window.

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. On the menu bar, click Customize > Toolbars > Production Feature Builder.
3. Click the Launch Feature Builder button on the Production Feature Builder toolbar.

   The Feature Builder window appears in ArcMap.

   The Feature Builder window

   提示:

   The Feature Builder window can be placed anywhere in ArcMap, or in the TOC, with the aid of the arrows showing the possible placement positions.

4. Click the Settings button at the top of the Feature Builder window.
   The Feature Builder Settings dialog box appears.
5. Click General on the left-hand pane.
6. Click the cell next to Scratch Spatial Reference.

   This allows you to specify the coordinate system, spatial domains, and precision of the scratch dataset.

7. Click the ellipsis button (...) in the cell.

   The New Spatial Reference dialog box appears.

8. To use a predefined spatial reference, click Select.

   The Browse for Coordinate System dialog box appears.

9. Navigate to the geographic or projected coordinate system you want to use with the scratch database.
10. Click Add.

    The New Spatial Reference dialog box appears.

11. Click Next.

    The New Spatial Reference dialog box appears with properties for x- and y-values. Default values for the coordinate system you have selected appear in the text boxes.

12. If necessary, type a new minimum value for latitude in the Min X text box.
13. If necessary, type a new maximum value for latitude in the Max X text box.
14. If necessary, type a new minimum value for longitude in the Min Y text box.
15. If necessary, type a new maximum value for longitude in the Max Y text box.
16. If necessary, type a new value for the precision in the Precision text box.
17. Click Next.

    The New Spatial Reference dialog box appears with properties for z-values. Default values for the coordinate system you have selected appear in the text boxes.

18. If necessary, type a new minimum value for z-values in the Min text box.
19. If necessary, type a new maximum value for z-values in the Max text box.
20. If necessary, type a new value for the precision in the Precision text box.
21. Click Next.

    The New Spatial Reference dialog box appears with properties for m-values. Default values for the coordinate system you have selected appear in the text boxes.

22. If necessary, type a new minimum value for m-values in the Min text box.
23. If necessary, type a new maximum value for m-values in the Max text box.
24. If necessary, type a new value for the precision in the Precision text box.
25. Click Finish.

    The Feature Builder Settings dialog box appears.

26. Click OK.
