Saving and loading a JOSM session

It is possible to save a JOSM session similar most GIS software (in QGIS we call it a project file). The JOSM session saves your current map view, OSM data and loaded layers such as imagery.

The JOSM session is available in File menu. You need to be in Expert mode to access this feature.
To activate Expert mode, go to JOSM Preferences, activate Expert mode by clicking the checkbox.

Saving a JOSM session

Load any of your preferred layers in JOSM.
Save the JOSM session file clicking, File > Session > Save session as … Select any layers you want loaded when you start a new JOSM session.


Loading a JOSM session

To load a previously saved JOSM session, click File > Session > Load session. Select the .jos you saved.


NOTE: Do not save any OSM data within your .jos file. Always load new data to avoid data conflicts.

Examples of session files we use in the /mapping repo.
