Inserting the JOG Elevation Tints element (Defense Mapping)

The JOG Elevation Tints is a surround element that displays the elevation values based on a series of hypsometric bands. It provides a quick reference for general terrain elevation, with the number of bands depending on the amount of difference in elevation.

Once inserted, double-clicking the JOG Elevation Tints element allows you to access the JOG Elevation Tints Properties dialog box. The Update dynamically check box on the JOG Elevation Tints tab is checked by default. When this check box is checked, the elevation tints can update dynamically based on the active data frame or on what you specify for the following:

• Elevation feature layer
• Elevation field
• Elevation data units

Unchecking the Update dynamically check box allows you to choose the elevation region (low, moderate, or high), as well as input for the high and low elevation values.

If the element needs to be altered after it is created, select the element in the layout view, click Convert To Graphics, then click Ungroup to ungroup the elements that were used to create it. Perform the required edits, then regroup the elements by clicking Group.
