The [Data Layers](/e/applications/jmap-ng-user-guide/the-data/data-layers.md) section offers details on these tools. 7. Select a base map from the BASE MAP group. The name of the selected map is displayed with the name of the group.

The base map attributions display at the bottom of the map.

## Filtering layers To speed up the identification of the layers that interest you, you can apply a filter. 1. Click on

2. Enter characters in the range **Layer Name** to filter the layers based on their name. 3. Click on

to open the **Add a filter** card. 4. Select the attribute from the **Filter by** list, the operator from the **Operator** list, and the value by which you want to filter the layers. 5. Click **Add**. The filter is displayed in the **Layer filters** box. Only the layers that pass the filter are displayed in the **Layers** panel.

6. Click on
