XML scripts for custom annotation (Aviation)

The advanced callout/multiple text element functionality receives and interprets all the required information from an XML script. For example, you can display the text in the top text element differently than the bottom text element by specifying different attributes for each parameter within each unique identification tag. This XML script is ingested into a visual specification rule for each type of annotation that needs to be created. Once the rule is calculated, the appropriate field of the cartographic feature class is populated, and annotation can be created.

XML script examples for custom annotation

These XML examples show how the parameters can be used.

The first example is hypothetical and is meant for coders/scripters/developers to have an idea of how to use the script. The second example is a complex script that calculates the cartographic feature class to create the Navaid annotation feature class based on the calculated field. The third example is formatted to allow annotation to be abbreviated.
