Adding the mercator scale bar

The mercator scale bar is a customized scale bar displayed on aeronautical charts using a mercator projection.

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 main menu, click View > Layout View.
3. On the main menu, click Customize > Toolbars > Aeronautical Layout.
4. Click the Mercator Scale Bar button on the Aeronautical Layout toolbar.

   By default, the mercator scale bar represents the current focus map scale if it is not zero.

   注意:

   The mercator scale bar is not dynamically linked to the data frame properties; scale changes do not automatically update the mercator scale bar element.
