# Import ## JMap Importation User Guide JMap Importation extension allows users of the JMap Pro application to import spatial vector and raster data sets and to add them as a layer in a project. This layer is ephemeral and will disappear when the session is terminated. However, the contents of this layer can be copied to an editable project layer or to a personal layer. For more information on copying elements from one layer to another, refer to the [JMap Edition User Guide](https://docs-jmapserver-lima.k2geospatial.com/e/extensions/edition). For more information on personal layers, refer to the [JMap Pro User Guide](https://docs-jmapserver-lima.k2geospatial.com/e/applications/jmap-pro-user-guide). --- # Agent Instructions: 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.
