This icon ![](/files/aZ67OT92lngf1iHt8BCo) located in the **Layers** section of the project interface also takes you to the **Layers** tab. The table shows basic information about each layer of the project. When you click on the name of a layer, a details section displays. In this tab you can define the order of layers in the project. The [Organizing Layers](/e/administrator/jmap-server-administrator-manual/resources-projects/configuring-projects/managing-layers/organizing-layers.md) section offers details on this topic. Buttons allow you to perform management tasks for the layers you select in the table, as well as add new layers to the project. ## Add layers

Clone/Reference	Allows you to duplicate or reference a layer from another project located on the same server or on a different JMap Server. Refer to Sharing Layers.
Import…	Allows you to import layers one by one from a project exported from another JMap server. Refer to Importing layers.

{% hint style="info" %} The icon ![](/files/YAO1WY3e46KcU0HcFZjT) in the **Layers** section of the project configuration interface gives you the three options to add a layer to the project. {% endhint %} ## Permissions When you select one or more layers you can grant permissions for the whole set.

## Synchronize with JMap Cloud This button allows you to synchronize the selected layers with JMap Cloud. The section [Sharing layers with JMap Cloud](/e/administrator/jmap-server-administrator-manual/resources-layers/sharing-layers.md#sharing-layers-with-jmap-cloud) provides details on the subject. ## Delete Deletes the selected layers. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs-jmapserver-lima.k2geospatial.com/e/administrator/jmap-server-administrator-manual/resources-projects/configuring-projects/managing-layers.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
