Layer Properties

This section allows you to configure the layer properties, through the following parameters:

Source

Indicates the layer's data source. Click the data source name to open the data source description interface.

Name

The name of the layer. You can modify the name.

Description

Description. Optional parameter.

Zoom levels

Select the zoom levels at which the layer is visible. 24 zoom levels are available. Level 0 corresponds to the entire planet (maximum zoom out), while level 23 corresponds to the closest zoom to a point on the map (maximum zoom in). Restricting the visibility threshold of some layers improves application performance and map readability. This visibility threshold can be enabled or disabled using the layer's switch ( and ).

Rotation

Point features only. Check this setting to rotate the layer's elements based on a quantitative attribute. You must select the attribute and the rotation direction (clockwise or counterclockwise).

Generalization level

Select a generalization level. Generalization is the simplification and adaptation of the layer's content to make the map more readable and the application more efficient without losing accuracy. Four options are available: None, Low, Medium, and High.

Enable editing tools

Check this setting to provide layer data editing tools to application users with the necessary permissions. If this option is enabled, layer data is no longer cached.

Attributes

This section displays the list of layer attributes. The attributes are listed in alphabetical order. The name, title, and type (double, integer, varchar, date) are displayed for each attribute. When you check an attribute, it becomes available for use in styles, labels, and popups. It is moved to the top of the list. When you uncheck it, the attribute is no longer available for configuring styles, labels, or popups and returns to its original position in the list. You can edit the title of each attribute:

  1. Check the attribute you want to edit. The attribute is moved to the top of the list, and the Title field becomes editable.

  2. Enter the title and accept the change.
