Layer List Dialog
Keyboard shortcut: Shift+Alt+L
List of currently loaded layers.
Showing and Hiding the Layer List Dialog Window

- Show the Layer List Dialog Window by pressing
Shift+Alt+L
. - Use the Windows menu.
Layer types
There are different types of layers. Each has a Context Menu accessed from the right mouse button which provides operations on the layer.
- OSM Data Layer (menu): holds the OpenStreetMap data (nodes, ways, relations).
- GPX Layer (menu): holds the GPS data loaded from your local hard disk (by using the open dialog to load GPX files) or from openstreetmap. The context menu (right mouse click on layer in layer list) allows to set special properties for different gps layers (different colors, line style, etc.).
- Marker Layer (menu): Markers are specially identified points on the track. They come in four varieties: simple named markers, audio markers, image markers and web markers. They are created as a side effect of opening a GPX file, containing waypoints from that file, or from a set of waypoints artificially constructed using the context menu entry Make Sampled Audio Layer on the GPX layer, which produces only audio markers.
- Photo Layer (menu): the context menu (right mouse) of a GPS layer provides the menu to import images. Using this feature allows to match digital images with the gps coordinates to ease the naming of streets (for example).
- Imagery Layer (menu): backgrounds retrieved from a WMS, TMS or WMTS server. Examples are Landsat satellite imagery, Bing Aerial, NPE out-of-copyright Ordnance Survey maps and OpenStreetMap map tiles. See also Imagery.
- Validator Layer (menu): highlights objects with errors or warnings from the Validator
- Notes Layer (menu): displays the position of downloaded Notes in the Map view.
There might be more layer types depending on the loaded plugins, e.g. Mapillary plugin.
Layer Buttons
- click to make the layer the active layer
- click to snap/unsnap the zoom to native resolutions of this background imagery layer
- click to hide/unhide the layer
Panel Buttons
The Layer List Dialog also has several buttons at the bottom which operate on the selected layers:
Move Up
Up moves the selected layers up one row in the layer stack.
This is important when items in one layer obscure those in layers below.
Move Down
Down moves the selected layers down one row in the layer stack.
This is important when items in one layer obscure those in layers below.
Activate Layer
Keyboard shortcut: Shift+A+[0-9]
- counting from the top
Activate activates the selected layer.
It is only possible to edit in an active Data layer.
Visibility
- A checkbox to show/hide a layer, i.e. turns visibility of selected layers on or off. The layers are unchanged when hidden, but their contents are not shown. You can also use the following shortcuts to show/hide a layer:
Shift+S+[0-9]
- counting from the topAlt+[0-9]
- counting from the bottom
- A bar to adjust the Opacity of selected layers in percent.
- A bar to adjust the Colorfulness of selected layers.
- A bar to adjust the Gamma of selected layers.
- A bar to adjust the Sharpness of selected layers.
Colorfulness, Gamma and Sharpness are only availible for imagery layers.
Delete Layer
Delete permanently deletes the selected layers. All unsaved changes will be discarded!
If you try to delete OSM data layers which contain changes, JOSM will open the Unsaved Changes Dialog, asking to upload and/or save these changes.
Individual Buttons
There might be more buttons depending on the loaded plugins, e.g. RasterFilters plugin.
