    <div class="moz-cite-prefix">Thanks for the clarification, Pierre.<br>
      Actually, I tagged the relation both with natural=water,
      water=river and waterway=riverbank as advised in the wiki (see New
      Tagging) I assume this is the recommended way to do it?<br>
      <br>
      As for Obrero, I haven't been that far north yet :) I only traced
      it up to the point where someone else had traced it. I stopped
      around Sta Rosa:

      But, yes I agree, that needs to be retraced. It was probably
      traced from an old lower resolution satellite image like some of
      my own earlier work.<br>

        It is not necessary fo merge the two relations, Each of these

            <div class="y_msg_container"><br>
              I've been adding polygons for Pampanga River and some of
              its contributories, <br>
              starting near Mt Arayat and working myself northward,
              joining up with the <br>
              existing multipolygon - <a moz-do-not-send="true"
                href="http://www.openstreetmap.org/relation/2411084."
                target="_blank">http://www.openstreetmap.org/relation/2411084.
              </a>I then <br>
              worked myself southwards until I found another
              multipolygon for Pampanga River <br>
              - <a moz-do-not-send="true"

                target="_blank">http://www.openstreetmap.org/relation/2913607
              </a>.<br>
              Is there a way to merge these?<br>
              Or doesn't it matter that the river is split into several
              multipolygons as <br>
              long as they are joined by shared nodes?<br>
