Add the Elevation Guide Bar

获得 Defense Mapping 许可后可用。

The Elevation Guide Bar surround element is a legend that defines the elevation bands displayed in the Elevation Guide map frame of a Topographic Map (TM) product. The Elevation Guide Bar accentuates the highest and lowest shape and elevation of the terrain and is a quick reference for general landforms.

注：

The Elevation Guide map frame can be found in the layouts for TM products in the ArcGIS Defense Mapping product files folders.

The number of bands displayed in the Elevation Guide Bar depends on the differences in elevation on the map. Elevation bands are created using an elevation bands feature class that you must create using the Generate Elevation Guide Features tool before the Elevation Guide Bar surround element can be added to a TM product. The number of bands in the Elevation Guide Bar is dependent on the number of bands identified in the feature class. There can be two, three, or four bands with the following labels:

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

注：

The Elevation Guide Bar element is not displayed when there is only one elevation band.

You can manually set the number of bands displayed in the Elevation Guide Bar in the Element pane. If your data is from a source that does not have the Number of Bands field defined, you must manually define the number of bands in the Element pane.

Insert an Elevation Guide Bar

Once the elevation bands feature class is created with the Generate Elevation Guide Features tool and the associated Elevation Guide map frame is active, the Elevation Guide Bar element can be inserted. Complete the following steps to insert the element:

1. Ensure that a layout with a map frame is open and is the active view in your project.
