Babak, Just recently delivered the SLDs for rendering TOP50NL for the Dutch Cadastre, so these pictures are well known to me! If I am correct, you are trying to render a wide motorway on a bridge, right?
You create 4 FeatureTypeStyle elements, so you are sure that first the bridge
is drawn in black, then the white surface of the bridge.is drawn. Thirdly, the
black casing of the motorway is drawn and lastly the purple fill. If you don't
apply 4 FeatureTypeStyle elements, but list all LineSymbolizer elements
together, you will find black and white cropping up all over, depending on the
order in which the geometries are drawn.
So, for the wide motorways, you first define a LineSymbolizer with a
stroke-width of 9 and a colour in black. Then a LineSymbolizer with a
stroke-width of 7 and a colour of white. This creates the illusion of two
perpendicular black lines in black that have a width of 1px! Thirdly, you
define a LineSymbolizer with a stroke-width of 5 and a colour of #4e4e4e and
finally a LineSymbolizer with a stroke-width of 3 and a colour #996089. Play a
bit with the widths and opacity of the strokes, because 1px lines tend to blur
easily.
Also, you may want to adapt your filter to allow for more VISUALISATIECODE
values that refer to the same object!
Kind regards,
Edward

Subject: [Geoserver-users] SLD problem
Hi,
I have a problem with making of a SLD. I try make a SLD for an object. I want
make something like this picture:
I try this <Rule> in SLD:
<Rule>
<Name>Typeweg=</Name>
<Title>autoway </Title>
<ogc:Filter>
<ogc:PropertyIsEqualTo>
<ogc:PropertyName>VISUALISATIECODE</ogc:PropertyName>
<ogc:Literal>21005</ogc:Literal>
</ogc:PropertyIsEqualTo>
</ogc:Filter>
<MinScaleDenominator>4700</MinScaleDenominator>
<MaxScaleDenominator>154000</MaxScaleDenominator>
<LineSymbolizer>
<Stroke>
<CssParameter name="stroke">#4E4E4E</CssParameter>
<CssParameter name="stroke-linetype">cartoline</CssParameter>
<CssParameter name="stroke-width">5</CssParameter>
<CssParameter name="stroke-linecap">butt</CssParameter>
<CssParameter name="stroke-linejoin">miter</CssParameter>
</Stroke>
</LineSymbolizer>
<LineSymbolizer>
<Stroke>
<CssParameter name="stroke">#996089</CssParameter>
<CssParameter name="stroke-linetype">cartoline</CssParameter>
<CssParameter name="stroke-width">3.5</CssParameter>
<CssParameter name="stroke-linecap">round</CssParameter>
<CssParameter name="stroke-linejoin">round</CssParameter>
</Stroke>
</LineSymbolizer>
<LineSymbolizer>
<Stroke>
<CssParameter name="stroke">#000000</CssParameter>
<CssParameter name="stroke-linetype">cartoline</CssParameter>
<CssParameter name="stroke-width">1.5</CssParameter>
<CssParameter name="stroke-linecap">round</CssParameter>
<CssParameter name="stroke-linejoin">round</CssParameter>
<CssParameter name="stroke-dashoffset">5</CssParameter>
</Stroke>
</LineSymbolizer>
<LineSymbolizer>
<Stroke>
<CssParameter name="stroke">#000000</CssParameter>
<CssParameter name="stroke-linetype">cartoline</CssParameter>
<CssParameter name="stroke-width">1.5</CssParameter>
<CssParameter name="stroke-linecap">round</CssParameter>
<CssParameter name="stroke-linejoin">round</CssParameter>
<CssParameter name="stroke-dashoffset">-5</CssParameter>
</Stroke>
</LineSymbolizer>
</Rule>
I see that offset not work. And doesn’t matter if set this line in the SLD or
not:
<CssParameter name="stroke-dashoffset">-5</CssParameter>
Anyone know about this issue.
