Inserting the TLM Elevation Guide Bar element

The TLM Elevation Guide Bar surround element is used to display the high and low elevation on a Topographic Line Map (TLM) with a series of hypsometric gray bands. It provides a quick reference for general landforms and accentuates the highest and lowest shape and elevation of the terrain.

The number of hypsometric bands that are displayed will depend on the difference in elevation within the map as follows:

• Two bands—Low and High
• Three bands—Low, Medium, and High
• Four bands—Low, Medium, High, and Highest

注意:

The surround element is not displayed when only one elevation band is present.

Before inserting this element, you must verify the associated data frame is active. Once inserted, double-clicking the TLM Elevation Guide Bar element allows you to access the TLM Elevation Guide Bar Properties dialog box. The Update Dynamically check box on the TLM Elevation Guide Bar tab is checked by default. When this check box is checked, elevation guide bar properties are automatically updated dynamically based on the associated data frame.

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. Verify that the map is in layout view.
3. On the main menu, click Customize > Toolbars > Defense Mapping.
4. On the Defense Mapping toolbar, click Defense Mapping > Surround Elements > TLM Elevation Guide Bar.

   An elevation guide bar appears in the center of the focused data frame of the page layout.

5. Double-click the elevation guide bar.

   The TLM Elevation Guide Bar Properties dialog box appears.

6. Click the TLM Elevation Guide Bar tab.

   The TLM Elevation Guide Bar tab appears with the Update Dynamically check box checked by default.

   When this check box is checked, properties are automatically updated dynamically with the associated data frame. Unchecking this check box causes the surround element to stop responding to data frame events such as zoom in, zoom out, pan, and so on. The Elevation Band Feature Class text box also becomes unavailable.

7. If necessary, check the Update Dynamically check box if you want the elevation guide bar to update dynamically.
8. Click Browse.

   The Browse dialog box appears.

9. Navigate to where the elevation band feature class you want to use is located.
10. Click Select.
11. In the Elevation Band Bar Location area, click one of the following options:
