Vector Layers

There are two types of vector layer that can be added:

• Simple - specify attributes for a specific class
• Thematic - specify attributes depending on the value of a property in that class

To add a vector layer, click the Vector Layer button in the Styles page, then select Simple or Thematic.

For both Simple and Thematic layers, a list of classes is displayed, from which you can select a class to add to the list.

Note: To display secondary geometries, add a vector layer. When you add a vector layer, you can select which geometry to draw for the layer. To display more than one geometry of a feature, add vector layers for each geometry.

Adding Simple Vector Layers

Once a feature class has been selected for a Simple Vector Layer, the symbology options are displayed and can be edited.

Adding Thematic Vector Layers

Once a feature class has been selected for a Thematic Vector Layer, the layer must be configured.

Select the feature class from the styles list, then click the Configure button.

For each different property value that requires a different symbology, click Add Rule. A rule allows you to define a property value and the styles to use when drawing features whose property equals the specified property value.

A default rule can also be added, to define the style behaviour for when no other rules are satisfied. Any features that are not identified by any other rule will be drawn in the default rule style, otherwise these features will not be drawn (but are still selectable). Click Add Default Rule, and then define the style options.
