Choosing an existing spatial reference for the solution

The spatial reference that will be used when the product class is created needs to be defined at the solution level of the product library. The areas of interest will be stored using this spatial reference. The steps below are to define an existing spatial reference, but you can also define a new spatial reference for your solution.The existing spatial reference can be defined in the New Solution or the Solution Properties dialog box. You can choose to use any spatial reference that is available within the product library.

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 you do not have the New Solution dialog box open, right-click an existing solution from the product library tree view and choose Properties to open the Solution Properties dialog box.
3. Click the plus sign (+) next to AOI Spatial Reference.
   提示:

   You can do this in the New Solution or the Solution Properties dialog box, depending on which one you have open.
4. Verify that the value for Use Existing is set to True.
5. Click the cell next to Base Spatial Reference and click the ellipsis (...) that appears.

   The Choose Existing Spatial Reference dialog box appears.
6. Click the Spatial Reference drop-down arrow and choose the spatial reference that you want to use with all the areas of interest within the solution.
   提示:

   You can view the properties of the spatial reference by clicking the Properties button .

   提示:

   The Links tab displays the names of product library tree levels that are using the spatial reference you selected.

7. Click OK.

   The New Solution or the Solution Properties dialog box appears, depending on which one you have open.

8. Click OK.
