Re: [UMN_MAPSERVER-USERS] layer grouping

[Bart van den Eijnden (OSGIS)]

Hi Laura,

have a look at the *wms_layer_group *metadata, which can take an xpath 
like expression for you to define a hierarchy, see also:

Best regards,

Hi there,
i am trying to configure some available layers in mapserver, i would like to group some 
of them, i found no problem creating just one grouping level:
<Layer>
        <Layer>
        </Layer>
        <Layer>
        </Layer>
</Layer>
for this i just add the TAG GROUP to the layers i want to group, the problem comes 
when i want to configure two or more levels like this:
<Layer>
        <Layer>
                <Layer>
                </Layer>
        </Layer>
        <Layer>
        </Layer>
</Layer>
My problem comes because the layer that groups a set of layers is not a layer itself so i 
cant make a reference to it, if i create a layer as a LAYER to be the GROUP of some 
sublayers, then this layer appears two times in the capabilities.
any ideas to create this second level of layer grouping??
here part of the layers definition on my map file:

#LAYER
#  NAME ProtectedAreas  
#  METADATA
#    "wms_title" "Protected Areas"
#  END       
#  STATUS OFF
#  TYPE ANNOTATION
#END

LAYER
 NAME zepa
 GROUP ProtectedAreas
 METADATA
   "wms_title" "Zepa zones"
   "wms_group_title" "Protected Areas"
   gml_include_items "all"
 END       
     STATUS ON
     TYPE POLYGON
     DUMP TRUE
     PROJECTION
        "init=epsg:23030"
     END      
     CONNECTIONTYPE postgis
     CONNECTION "user=***** password=***** dbname=costas host=192.168.0.0"
     DATA "the_geom from (select * from zepa) as foo using unique gid = using 
SRID=23030"      
 TOLERANCE 3
 CLASS   
   NAME "zepa"
   TEMPLATE 'gmap/htdocs/templates/popplace.html'
   COLOR 0 240 240
   OUTLINECOLOR 199 199 199   
 END
END

LAYER
 NAME mreservas
 GROUP ProtectedAreas
 METADATA
   "wms_title" "Microreservas"
   gml_include_items "all"
 END       
     STATUS ON
     TYPE POLYGON
     DUMP TRUE
     PROJECTION
        "init=epsg:23030"
     END      
     CONNECTIONTYPE postgis
     CONNECTION "user=***** password=***** dbname=costas host=192.168.0.0"
     DATA "the_geom from (select * from mreservas) as foo using unique gid = using 
SRID=23030"      
 TOLERANCE 3
 CLASS   
   NAME "mreservas"
   TEMPLATE 'gmap/htdocs/templates/popplace.html'
   COLOR 0 240 240
   OUTLINECOLOR 199 199 199   
 END
END


thanks,

Laura.
