Find out about the data in a layer
You can find information about the data in a layer by using the Layers panel. The panel indicates what kind of data source is used by each layer, as described in the table below.
To find out more about a layer, and to configure its appearance, click the arrow shown next to the layer name, or click the layer name and click Layer Details. In the Layer Details panel you can view information about the services that have been added as layers, turn sublayers on and off, and configure pop-up information windows and layer symbololgy.
What kind of data does each layer contain?
Layers with the icon | Contain this type of data |
|---|---|
 | The layer contains features that are stored in the map, and may contain a variety of feature types—point, line, area and text; for example the default Map Notes layer included by default in new maps. You can edit the features of these layers, add new features, and define new feature templates from which to create other new features. You can change the content of the pop-up windows. |
   | The layer contains features that are stored in the map, and the features are a single type of shape—point, line or area features. They are created by importing data into the map. You can turn each individual feature on or off. You can edit the features of these layers. You can configure the appearance and pop-up windows for these services, and use them in dashboard gadgets. |
  | The layer references a feature service that contains point, line or area features. Some feature services are editable. You can configure the appearance and pop-up windows for these services. You can also use these layers in dashboard gadgets and queries. |
 | The layer references a map or image service, or a WMS service. You can configure the appearance of pop-up windows for map services. You can get more details about the service by clicking the Service Details button, as described in the section below. |
 | The layer references KML or KMZ data. You can control the opacity and the visibility of the layer, including the folders within it. |
 | This icon indicates the basemap. This layer is always at the bottom of the map. It cannot be turned on or off, and you cannot change its appearance or opacity. |
To view details of layers that are based on services
To view the details of the service associated with a layer, open the Layers panel. Click the Layers tab in the left side panel, click the arrow on the right of the item to show the Layer Details view, then click the Service Details button. The details of the service will open in a new page or window of your web browser.
The available information varies depending on the type of service. For example, for an ArcGIS map, feature or image service, the Services Directory is a view of the ArcGIS Server REST API in HTML format. Each ArcGIS Server instance has a Services Directory installed during its installation process. If you click a service listed in the directory, you will see information such as a description of the service, a list of the available layers, a description, copyright information, the spatial reference, and so on. Below, you can see some of the map service description page for an ArcGIS tiled map service.
