Inserting the TLM Elevation Guide Bar element
The TLM Elevation Guide Bar surround element is used as a legend to define the high and low elevation displayed in the ElevationGuide data frame on a Topographic Line Map (TLM). The Elevation Guide Bar provides a quick reference for general landforms and accentuates the highest and lowest shape and elevation of the terrain.
The ElevationGuide data frame can be found on the template for the TLM product. The templates can be found in the [installation directory]\Program Files\ESRIDefenseMapping\Desktop10.0\VMap2TLM\Cartography\MapTemplates directory.
The number of hypsometric bands that are displayed in the Elevation Guide Bar depends on the differences in elevation within the map. The bands are created based on an elevation bands feature class that has been created using the Bands From Raster or Bands From Features geoprocessing tools. The number of bands in the TLM Elevation Guide Bar is dependent on the number of bands identified in the feature class. There can be two to four bands, labeled as follows:
- Two bands—Low and High
- Three bands—Low, Medium, and High
- Four bands—Low, Medium, High, and Highest
The surround element is not displayed when only one elevation band is present.
You can also override the number of bands displayed in the TLM Elevation Guide Bar element by modifying its properties. If your data is from a source that does not have the Number of Bands field, you can define the number of bands to display on the TLM Elevation Guide Bar Properties dialog box.
Before inserting this element, you must verify that the associated Elevation Guide 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.
