I have real time traffic data which has values for one link/line in both directions e.g. value 0 (green) in the digitalisation direction and value 3 (red) against the digitalisation direction.<br>At the moment this is done with OFFSET x -99 and works well. I see the link two times with, if available, two different values<br>
<br> CLASS <br> NAME C_0_0 <br> EXPRESSION (([value_los] = 0) && ([linkdirection] = 0))<br> STYLE<br> COLOR 0 117 0<br> WIDTH 3<br>
ANTIALIAS TRUE<br> OFFSET 2 -99<br> END<br> END<br> CLASS <br> NAME C_0_1 <br> EXPRESSION (([value_los] = 0) && ([linkdirection] = 1))<br>
STYLE<br> COLOR 0 117 0<br> WIDTH 3<br> ANTIALIAS TRUE<br> OFFSET -2 -99<br> <br><br>Now I wanted to use SLD with UserStyle - the color and width is changeable, but I noticed that the OFFSET was overruled and so I dont see different values for separate directions. I found no parameter in the SLD for the Offset of a line.<br>
So my workaround is SLD with NamedStyle - I copied the Classes and the first are in group1 the last in group2. I switch in the one layer with the name of the group.<br>So my question is - is it possible to use UserStyle SLD with the possibility to set a usefull offset or could the offset in the mapfile could be used even if nothing more is defined in the SLD.<br>
Thanks for your support/ideas.<br>BR,<br>Hannes<br>
