Applying a masking set (Defense Mapping)

Masking settings allow you to determine what layers block out, or mask, parts of other layers. Masking can improve legibility of text on a chart and improve cartographic depiction of features. You can determine which features mask other features by creating a set of masking rules. Once you have created a masking set, you can apply it to feature layers in a chart.
