Re: [Geoserver-users] Style clipped ends of a LineString?

[Mauro B. <mau...@ge...>]

Hi Mihail,
the correct answer probably depends on the way your route segments are
available. Assuming you have them as a single LineString geometry where the
end points are the first and last point of the LineString one way to show
them would be to use the startPoint and/or endPoint functions inside a
Geometry transformation.

An example here:

<PointSymbolizer>
    <Geometry>
        <ogc:Function name="startPoint">
            <ogc:PropertyName>geometry</ogc:PropertyName>
        </ogc:Function>
    </Geometry>
    <Graphic>
        <Mark>
            <WellKnownName>circle</WellKnownName>
            <Fill>
                <CssParameter name="fill">#FF0000</CssParameter>
            </Fill>
        </Mark>
        <Size>12</Size>
    </Graphic>
</PointSymbolizer>

Can you try to explain in more detail how you store your route line
segments and what is the final result you expect?
