Class: WfsPermalink service:ngeoWfsPermalink

WFS permalink service that can be used to load features with a WFS GetFeature request given query parameters.

Resulting features are then highlighted and the map is zoomed to the nearest map extent.

Parameters:

  • wfs_layer tells what layer will be queried
  • wfs_showFeatures (boolean) tells if the features should be highlighted and listed (when true) or if the map should only be recentered on the features (when false). Default is true.
  • other parameters will be considered as WFS attribute/values filters and must be of the form: wfs_<layer attribute name>=<a comma-separated list of values>

Example: http://example.com?wfs_layer=parcels&wfs_city=Oslo&wfs_number=12,34,56 will load parcels #12, 34 and 56 of the city of Oslo.

It is possible to define several groups of filtering parameters by:

  • adding a wfs_ngroups parameter telling how many groups are defined
  • prefixing all filtering parameters by the number of each group, starting at 0. For instance wfs_0_<layer attribute name>

Example: http://example.com?wfs_layer=parcels&wfs_ngroups=2 &wfs_0_city=Oslo&wfs_0_number=12,34,56&wfs_1_city=Paris&wfs_1_number=78,90 will load parcels #12, 34 and 56 of the city of Oslo as well as parcels #78 and 90 of the city of Paris.
