[mapserver-users] WFS Server Layer styles not displaying

[Rahkonen Jukka]

Hi,

Mapserver can also create SLD file without additional scripts by implementing GetStyles request which is a part of WMS standard.  You can try how it works
http://188.64.1.61/cgi-bin/ms_ows?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetStyles&LAYERS=sea

The SLD files generated by GetStyles are very basic and do not make the same result as advanded Mapserver styles but try if the result with doing both WFS GetFeature and WMS GetStyles happens to be good enough for you.

Hi,

If I understood right you are using Mapserver as a WFS server and and you
await that your WFS client, for example QGis, shows the layer with similar
styles than it shows the same Mapserver layer through WMS.

WMS and WFS are very different things. WFS sends pure data in XML format and
there are attributes and coordinates but no colors nor line widths.
Something like this
http://188.64.1.61/cgi-bin/tinyows?service=WFS&version=1.1.0&request=GetFeat
ure&typeName=lv:mml_paikannimet20&maxFeatures=20

For the client WFS is a vector layer and you must define the styles on the
client side. However, automatic styling of WFS layers might be possible by
utilising the OGR feature style system
http://fi.search.yahoo.com/search?p=ogr+feature+style+support&ei=UTF-8&fr=mo
z35
Currently Mapserver can convert OGR styles from the source data into
Mapserver classes.
http://www.mapserver.org/input/vector/ogr.html#styleitem-auto-rendering-laye
rs-using-style-information-from-the-ogr-file

If Mapserver could do it in an opposite way and populate an additional
OGR_STYLES field of WFS Feature Type from layer styles and if the WFS client
could utilize OGR_STYLES automatically for rendering it might work. Perhaps
an idea for the Google Summer of Code?

Aihe: [mapserver-users] WFS Server Layer styles not displaying

Hello,

I have been recently testing mapserver with WFS layer.

The wfs layer appears – however it completely ignores my CLASS Styles. I
used WMS before – it worked without any issue.
Anything I am doing wrong here? Or Does mapserver doesn’t support styling
for WFS layers through CLASS definitions?

Here is my Layer Definition in map file . Using mapserver ver 6.0.2

LAYER
    NAME "bldg"
    METADATA
      "wfs_title"         "Building Footprints" ##REQUIRED
      "wfs_srs"           "EPSG:28356" ## REQUIRED
      "gml_include_items" "all" ## Optional (serves all attributes for
layer)
      "gml_featureid"     "ID" ## REQUIRED
      "wfs_enable_request" "*"
  END
    TYPE polygon
    STATUS OFF
    #DATA "site/bldg_region"
   CONNECTIONTYPE PLUGIN
                                                PLUGIN
"C:/ms4w/Apache/specialplugins/msplugin_mssql2008.dll"
    CONNECTION "server=abc;uid= abc;pwd= abc;database= abc;Integrated
Security=false"
    DATA "geom from bldg USING SRID=28356"

    TRANSPARENCY 100
    PROJECTION
      "init=epsg:28356"
    END
    CLASS
      NAME 'Building Footprints'
      STYLE
        COLOR 255 128 000
        OUTLINECOLOR 255 255 255
        WIDTH 2
      END
    END #class
  END #layer


Regards

Murad
