[Mapserver-users] Drawing lines only once

[Steve Lime]

Nope, not without altering the underlying GIS data. We have the same
problem here with county boundaries and maintain 2 versions of the data.
On line-based version for map making and one polygon-based version for
everything else.

I want to effectively draw boundaries of countries. Currently I have 
POLYGON data for each country and I want to draw the outlines for the 
countries but I only want to draw outlines where two countries meet 
once. My outline is defined as so:

CLASS
	COLOR 252 226 120
	SIZE 5
	SYMBOL 'solid'
	STYLE
		SYMBOL 'country_dash'
		SIZE 1
		COLOR 0 0 0
	END
END

SYMBOL # country_dash
   ANTIALIAS TRUE
   NAME 'country_dash'
   TYPE ELLIPSE
   POINTS 1 1 END
   FILLED true
   STYLE 1 3 10 3 END
END

So I am trying to get a thick solid yellow line with a thin black dots

and dashed centreline. The problem is that this gets drawn twice
because 
two countries of course share the same boundary so each draws its 
outline. Is there any way to only draw this boundary once?
