# Create and Manage Custom Maps

You can create custom maps in JMap NG to save them and share them with other users or external applications.

A custom map reproduces a specific map environment, including layers, styles, scale, measurements, annotations, and selected features.

All operations related to custom maps are performed from the **My Maps** panel.

To open it, click the **My Maps** button <img src="https://3291879974-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F9n1KCuTyIKwSpZcPcC6l%2Fuploads%2F3lgfLcxzu1dbfqO7eJUP%2Fpanneau-mescartes.png?alt=media&#x26;token=cf780a67-761e-4e3e-af67-7a274d5c09d3" alt="" data-size="line">.

* **Share Map and Copy Link** – Generates the URL and automatically copies it to the clipboard. A confirmation message appears.
