# Layer Permissions

There are several different types of permissions for a project’s layers. The following tables describe each one of these.

## Administrator permissions

<table data-header-hidden><thead><tr><th width="147.5"></th><th></th></tr></thead><tbody><tr><td><strong>Permissions</strong></td><td> </td></tr><tr><td>Remote access</td><td>Allows a user to access this layer through a JMap Server to JMap Server connection. This permission must be granted to the account of the user who established the secure connection between both JMap Servers. For more information on this topic, refer to the <a href="../../jmap-server-to-jmap-server-connections">JMap Server to JMap Server Connections</a> section.</td></tr></tbody></table>

## User permissions

<table data-header-hidden><thead><tr><th width="152.5"></th><th></th></tr></thead><tbody><tr><td><strong>Permissions</strong></td><td> </td></tr><tr><td>View this layer</td><td><p>Allows a user to view a layer in JMap’s applications. </p><p>By default, the everyone user (everyone who has permission to open the project) is authorized to view any new layer. </p><p>To restrict access to a layer, you must remove this permission from everyone and only add it to the users of your choice.</p></td></tr><tr><td>Add elements</td><td><p>Allows a user to add new elements on the layer and enter attribute values using the form associated with the layer. </p><p>Editing must be enabled on this layer in order for this permission to be available.</p></td></tr><tr><td>Modify elements</td><td>Allows a user to modify the geometries of the elements (move, add/remove nodes, etc.) found on the layer. Also allows the user to modify attribute values using the form associated with the layer. Editing must be enabled on this layer in order for this permission to be available.</td></tr><tr><td>Delete elements</td><td>Allows a user to delete existing elements on the layer. Editing must be enabled on this layer in order for this permission to be available.</td></tr><tr><td>Modify attribute values</td><td>Allows a user to open the form of a layer’s element attributes and to modify their values. Editing must be enabled on this layer in order for this permission to be available.</td></tr><tr><td>Copy / export elements</td><td>Allows a JMap Pro user to copy the data of the layer to another layer, or to export the data of the layer using the JMap Exportation extension.</td></tr><tr><td><strong>Options</strong></td><td> </td></tr><tr><td>Edit only own elements</td><td>Allows the user of a JMap application to modify the geometries, the values of the attributes or to delete only the elements that he has created in the layer. The user cannot edit the elements of the layer that were created by other users.</td></tr></tbody></table>

Only the users and groups who are already authorized to open the project containing the layer can be granted permissions associated with this layer.
