Layer style visualisation

How to change the way items are visualised​

Overview​

A layers style defines the items and how they are displayed within a layer on the map. You can change various display attributes to alter the way in which items are visualised on the map. Style visualisation can be configured in all types of layers using one of the following types of visualisation:

  • Basic - for Standard / Custom layer styles, item icons remain as individual items when you scale the map
  • Cluster - for Standard / Custom layer styles, item icons are clustered when you scale the map
  • Network - for network layer styles
  • WFS - for WFS layer styles
Note

The Basic visualisation type has a limit of 500 items, this is to guard against degraded performance if a large amount of individual items are loaded and rendered. Attempting to build a Basic layer style with more than 500 items will cause an error.

Accessing the style visualisation feature​

To access style visualisation use the following procedure:

  1. For Standard or Custom layers (including WFS layers) select the layers icon in the right panel menu to open the list of all layers.

    For network layers select the button in the right panel to open the list of all networks.

  2. Select a layer or network to display the list of styles.

You can now edit the the following fields:

  • Title - this allows you to enter a field title linked to data from the WFS service, for example if you link to a field in the data named service, then the contents is displayed in the layer labels as the title.

  • Subtitle - this allows you enter an additional field subtitle linked to data from the WFS service, for example if you link to a field in the data named address, then the contents are transferred to the Subtitle field.

The data from the WFS service will be displayed in the labels if you activate the Label mode.
