How do you maintain and review your representation rules?

Mapping organizations often create highly detailed maps with many complex symbols. This gives rise to the need to create and maintain symbol specifications. ArcGIS for Desktop provides feature class representations to customize the appearance of features by storing symbol information with your feature geometry. This additional control allows for stringent cartographic specifications and improved map output, as a result of which many mapping organizations have adopted the use of representations.

The Representation Rule Dump Add-In (ArcGIS 10.1) aids in the creation of symbol specification documents such as symbol look-up tables and provides an easy way to perform QA/QC of your representation rules. The tool creates a new file geodatabase with three feature classes (point, line, and polygon) and assigns all the representation rules from a selected style file. The feature layers are added to the current active data frame of a map document. You can then use a graphic table or legend element to add the symbols to ArcMap’s page layout. You’re now ready to print and/or export the table in order to perform a more detailed review of your representation symbology.

    That lookup table is kind of cool but I never have understood the purpose of representations. Seems to me you could always create symbology to cover the types of things in the above table. The only thing I’ve ever really used representations for was a drop shadow for a building and really that is not something that is necessary. I’ve found that they can also be difficult and convuluted to set up. What are other peoples thoughts on this?

    No “Style” options, I can’t use the Representation Rule Dump Add-In.
