In QGIS, a WFS layer behaves pretty much like any other vector layer. You can identify and select features and view the attribute table. An exception is that editing is not supported at this time. To start the WFS plugin you need to open> ..., activate the checkbox and click .
A new icon appears next to the WMS icon. Click on it to open the dialog. In General adding a WFS layer is very similar to the procedure used with WMS. The difference is there are no default servers defined, so we have to add our own.
Loading a WFS Layer
As an example we use the DM Solutions WFS server and display a layer. The URL is:
- Make sure the WFS plugin is loaded; if not, open the Plugin Manager and load it
- Click on the mIconAddWfsLayerAdd WFS Layer tool on the plugins toolbar
- Click on New
- Enter NameDM Solutions as the name
- Enter the URL (see previous page)
- Click OK
- Choose Server ConnectionsDM Solutions from the drop-down box
- Click Connect
- Wait for the list of layers to be populated
- Click on the Canadian Land layer
- Click Add to add the layer to the map
- Wait patiently for the features to appear
<P> Note that the WFS-plugin also recognizes the proxy-settings you have set in your preferences.
<P> You'll notice the download progress is visualized in the left bottom of the QGIS main window. Once the layer is loaded, you can identify and select a province or two and view the attribute table.
<P> Remember this plugin works best with UMN MapServer WFS servers. It still could be, that you might experience random behavior and crashes. You can look forward to improvements in a future version of the plugin.
<P> This means that only WFS 1.0.0 is supported. At this point there have not been many test against over WFS versions implemented in other WFS-servers. If you encounter problems with any other WFS-server, please do not hesitate to contacting the development team.
