Well - I fear, I used the word with one of meanings it has in German - 
but probably not in English
http://de.wikipedia.org/wiki/Signatur_%28Kartographie%29

A "Signatur" - other meanings can be translated to the English 
"signature" - in the context of cartography is the style a map feature 
is visualized - an icon, the style and colors of a line and so on.

;) What's the English word for that?
