You control all aspects of a layer through the layer's properties. There are two places where you can access and update properties for layers: the ribbon and the Layer Properties dialog box. The properties you can set will be different for different types of geographic data or whether you are designing a map for 2D or 3D. For example, when designing a 3D map, you define additional properties, such as elevation of the layer from the surface.
Most display properties, such as symbology and transparency, are set on the ribbon. To change these settings, select a layer in the Contents pane and use the contextual tabs on the ribbon.
Additional properties are available through the Layer Properties dialog box. The tabs on this dialog box are specific to the type of layer. For example, here are some of the properties for feature layers you can set using the Layer Properties dialog box:
- General—Allows you to record a layer Name and Visibility range. You can also specify that a Layer should be refreshed periodically. A periodic refresh rate cannot be applied for layers that are time aware.
- Source—Allows you to view the extent of your data. You can view and change the source of your data from this tab.
- Elevation—Allows you to specify whether features display on the ground or are on the elevation surface for the map.
- Selection—Allows you to set how features in a specific layer are highlighted when they are selected.
- Display— Allows you to scale symbology when a reference scale is set in 2D, or show symbols in real-world units in 3D. In 3D you can also choose to compress textures to increase draw performance.
- Cache—Allows you to specify when to clear the cache for layers.
- Definition Query—Allows you to specify that a subset of your features will be used in the layer.
Most properties have only one location where you set them on the user interface and are not duplicated on both the ribbon and the Layer Properties dialog box.
- To set the properties that are available on the ribbon, click the layer in the Contents pane. Any settings you change are reflected immediately on the layer.
- To open the Layer Properties dialog box, right-click the layer in the Contents pane and click Properties, or double-click the layer name. Click the tab containing the properties you want to modify, make your changes, and click OK when you are finished.
