[mapserver-users] circular symbol for roads at border of tiles

[Andreas Heckwolf]

Hi all,

I am using mapserver 5.6.5, as installed on Debian stable, to render
tiles (WMS) to an OpenLayers map. Streets are rendered with a circular
symbol. Roads going across tile borders do have at the border a circle
visible. Please see picture at:

I understand what is happening, and why. Is there any way to avoid this,
or a better way of rendering streets?

Thanks,

Andreas


Here my SYMBOL definition and the styles:

  SYMBOL
    NAME "line_solid"
    TYPE ellipse
    POINTS 1 1 END
    FILLED true
  END


Then for the streets layer I have defined the following styles:

      STYLE
        SYMBOL 'line_solid'
        COLOR 130 130 130
        SIZE 12
      END
      STYLE
        SYMBOL 'line_solid'
        COLOR 255 255 200
        SIZE 10
      END
