Publishing WFS services

UMN Mapserver

• Add WFS support in your mapfile according to Mapserver documentation
• Test WFS locally using CGI with parameter ‘map’ pointing to your mapfile
• Set permissions for resources WFS and Topic
• URL after deployment: http://maps.example.com/wfs/MyWFS?SERVICE=WFS&VERSION=1.0.0&REQUEST=GetCapabilities

Tables without geometries

WFS expects a geometry column in a layer. If you want to publish a WFS without geometry, you can add an artificial geometry on-the fly:

LAYER
    NAME "mylayer" 
    STATUS on
    METADATA
       "wfs_enable_request"              "*" 
       "wfs_title"                       "My Layer" 
       "wfs_srs"                         "EPSG:21781 EPSG:21780 EPSG:4326 EPSG:31297 EPSG:4258" 
       "gml_include_items"               "all"   
       "gml_geometries"                  "none"  
       "wfs_featureid"                   "geodb_oid"    
    END
    INCLUDE 'connection.inc'
    DATA "wfsgeom FROM (SELECT *,ST_GeomFromText('POINT(680000 260000)', 21781) AS wfsgeom FROM mytable) AS subquery USING UNIQUE geodb_oid USING srid=21781" 
    TYPE POINT
END
