# Selecting Base Maps

You can select the base maps that will be available for your project. Base maps include maps based on other projects available in your organization.

By default, new projects use the base map provided by [OpenStreetMap](https://www.openstreetmap.org/).

**To add a base map to the project:**

In Studio, in the **Project** panel, under the **Base Maps** section:

1. Click **+** to open the **Add Base Maps** section.
2. Add a map by dragging and dropping it into the **Base Maps** section.
3. Add as many base maps as you wish.
4. Organize the maps by dragging and dropping them into the desired order.
5. Click the <img src="/files/N1L1QuhU3oxvONfYINn1" alt="" data-size="line"> icon that appears when hovering over a map to remove it.
6. If you want your project to display a default base map, check it.

## Using Projects as Base Maps

You can add another project as a base map for your project. Projects that can be used this way have certain requirements:

* Projects must be public or shared with the entire organization. If you want to add Project B as base map for Project A:

<table data-header-hidden><thead><tr><th width="197.12890625" valign="top"></th><th valign="top">Requirement</th></tr></thead><tbody><tr><td valign="top">If project A is <strong>Private</strong></td><td valign="top">Project B must be <strong>Shared with the entire organization</strong></td></tr><tr><td valign="top">If project A is <strong>Public</strong></td><td valign="top">Project B must be <strong>Public</strong></td></tr></tbody></table>

* You can add any other project that you can use (you have the **View** permission).
* Only the project's layers are added as a base map to your project.
* The project name becomes the base map name, preserving its multi-language support.
* If the project used as a base map is deleted or its permissions become more restrictive (the project is no longer public or is no longer shared with the entire organization), all base maps from that project are removed from all projects where they are used.

## Base Maps Available in JMap NG

Your choices determine the base maps available to users who open the project in JMap NG:

* The available base maps are those you added to the project.
* If you have not added any base map to the project, the **Base Maps** section does not appear.
* If you selected a default base map, it is displayed by default when the project is opened in JMap NG.
* If you have not selected a default base map, no base map is displayed when the project is opened.
* The base map order you established in Studio is preserved in JMap NG.
* Base maps from other projects function like standard base maps.
