ajouter plusieurs couches de fond de carte à une carte dans ArcGIS Pro

Résumé

In some cases, switching between multiple basemap layers is useful while viewing and editing the data of a map in ArcGIS Pro. However, attempting to add a new basemap layer using the Basemap button, updates the current layer instead of adding a layer to the map.

The newly added World Imagery basemap layer updates the previous Basemap.

Cause

Procédure

The following are two possible solutions to add multiple basemap layers to a map in an ArcGIS Pro project, adding layers from the Living Atlas, and adding layers from ArcGIS Online. In these workflows, only one basemap layer is added at a time. Repeat the steps to add multiple basemap layers as needed.

Add basemap layers from the Living Atlas content in ArcGIS Pro

Note:
While majority of the items in the Living Atlas are free, some items are considered subscriber and premium content.

1. In ArcGIS Pro, click Map > Add Data > Data.

2. In the Add Data window, click Portal > Living Atlas.
3. Type the title of the desired basemap layer in the Search Portal: Living Atlas box.
4. Select the desired basemap layer in the search results, and click OK.

Add basemap layers from ArcGIS Online to ArcGIS Pro

1. Add the desired basemap layer to ArcGIS Online. Refer to ArcGIS Online: Add items from the web.
2. Navigate to ArcGIS Pro, click Map > Add Data > Data.
3. In the Add Data window, click Portal > My Content.
4. Type the title of the basemap layer added to ArcGIS Online in the Search Portal: My Content box.
5. Select the desired basemap layer in the search results, and click OK.

Note:
Drag the newly added basemap layer to the bottom of the Drawing Order in Pro, so the basemap does not hinder viewing and editing.
