How do I make a dataset automatically display pre-defined symbols when I add it to a map? I would like to set pre-defined symbology for datasets in ArcSDE, so that when users add them to ArcMap they are automatically set. I know I can do this with a layer file, but I have some datasets that do this, too. These datasets came from USGS and I'm not sure how they set them up to display a given symbology set automatically.
Mapping Center Answer:
The only way to do this is to have a style referenced that has a symbol with exactly the same name as the value in the attribute that you want to use to apply teh symbology. For example, if you have an attribute called RoadType and there are values in it like "Major Road", "Minor Road, "Arterial", etc... AND you have a style referenced thad has symbols called "Major Road", "Minor Road, "Arterial", etc... then when you add the data in ArcMap the features will automatically be displayed with the right symbol. Note that no other referenced style can contain those symbols as well or the wrong symbology might be applied.
