Layers

When the Default check box is selected, the layer displays when the map renders. You can add a layer by clicking the Show Details tab above the map and selecting the check box next to the name of the layer. Clearing a check box removes that layer from the display.

When you select a layer with associated legend information, a column on the right of the map shows the legend. When multiple layers are displayed, the legends are listed in display order. As you modify the extents on the map by zooming, the data in the legends updates to reflect the correct level of detail. If a layer displays by default, the legend is not displayed until you click either the Show Details tab or the Show Table tab. Delaying the display conserves space on the map, which is relevant when a map is viewed in smaller spaces, such as in a portal. The column that displays the legends disappears after the last layer is removed.

The layer record requires that you specify the REST URL of the Esri server that is providing the map service. If the URL is correct and valid, the basemap service description that is provided by the Esri server renders on the bottom of the GIS Base Map form. If instead of the basemap service description, nothing displays or you see an error, confirm that your Esri server enabled the layer service with REST endpoints.
