  well, if you want only one line segment to have start markers, you must  tell mapserver which segment that is.

        hello

        I would like to add a symbol at the start and end of a polyline.

        I tried using GEOMTRANSFORM with "start" and "end" in a style block in the layer but sadely this will add a symbol to all start and end of every vertex of the polyline, which is not the result wanted :/

        is there any way to do that, beside creating a new point layer ?

        thanks in advance
        Oliver
