Hi, Check the GROUP parameter in the MapFile Documentation. With this you can merge many layers in one grouped Layer.<br><br>Regards<br><br>René Viancos<br><br><div><span class="gmail_quote">2008/3/25, Paul Austin <<a href="mailto:mail-lists@revolsys.com">mail-lists@revolsys.com</a>>:</span><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
What I would like to achieve is a WMS server where when the user selects<br> a layer (e.g. Water) that they see Line and Polygon water features<br> rendered where the lines are in the database table water_lines and the<br>
polygons are in the table water_polys. All the line features are<br> rendered first with the polygon features rendered on top of those.<br> <br> Is it possible with mapserver to define a layer which gets data from<br> multiple sources? Sort of like nested layers but where the user doesn't<br>
see the nested layers.<br> <br> An extension of this would to be also have different tables with data at<br> different scales so the 1:20k data would be in water_20k_lines and the<br> 1:250k would be in water_250k_lines.<br>
<br> Throughout all of this the user just sees the Water layer.<br> <br> Cheers,<br> Paul<br> _______________________________________________<br> mapserver-users mailing list<br> <a href="mailto:mapserver-users@lists.osgeo.org">mapserver-users@lists.osgeo.org</a><br>
