Hello,<br><br>I Have a vector layer with all the rivers, and subsidiaries up to the smallest water lines.<br>However I need to simplify this layer in order that it only shows the main rivers and first, second and third order tributary water lines.<br>
<br>Any hints on how to achieve this?<br><br>Best Regards,<br><br>André Mano<br clear="all"><br>-- <br>---------------------------------------------------------------<br>Associação Leonel Trindade<br>SOCIEDADE DE HISTÓRIA NATURAL<br>
