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?
Regards,
Mauro Bartolomeoli
