[[TranslatedPages(outdated=WIP to reflect the changes from #8039 (and #10456).)]] [[PageOutline(2-10,Table of Contents)]] = Layers window = [[Image(source:trunk/images/dialogs/layerlist.png)]] ''Keyboard shortcut'': **{{{Shift+Alt+L}}}** — one of the [Help/ToggleDialogs#Toactivateawindow JOSM windows] The Layers panel lists the **loaded layers**, controls their visibility and activates them for editing content. === Layer types === JOSM has several types of layers. Each has a Menu accessed from the right mouse button which provides operations on the layer. * [[Image(source:trunk/images/layer/osmdata_small.png,link=)]] [wikitr:/Help/Menu/OSMLayer Data layer] - Holds a set of map data [wikitr:/Help/Concepts/Object objects].\\ Map data can usually be downloaded, created and edited unless the [wikitr:/Help/Menu/OSMLayer#Layerstate layer state] is [[Image(source:trunk/images/warning-small.png,link=)]] [wiki:Help/Action/BlockDownload private] or [[Image(source:trunk/images/lock.svg,13px,link=)]] [wiki:Help/Action/LockedLayer locked]. A running upload is indicated by [[Image(source:trunk/images/clock.png,15,link=)]]. Some uploads are marked [wiki:Help/Action/EncourageDiscourageUpload risky] for OSM. * [[Image(source:trunk/images/layer/gpx_small.png,link=)]] [wikitr:/Help/Menu/GPXLayer GPX layer] - Holds GPS track data. Each GPX layer can have own properties like color, line style, etc. * [[Image(source:trunk/images/layer/marker_small.png)]] [wikitr:Help/Menu/Marker Marker Layer] - Holds identified points on a GPX track, called ''Markers''. They are created in four varieties: [wikitr:/Help/Action/MarkersFromNamedPoints Named], [wikitr:/Help/Action/ImportAudio Audio], [wikitr:/Help/Action/ImportImages Image] and Web. * [[Image(source:trunk/images/dialogs/geoimage.svg,16,link=)]] [wiki:Help/Menu/PhotoLayer Geoimage layer] - Holds images which were imported via a GPX layer, dragged on the [wikitr:/Help/MapView Mapview] or [wikitr:/Help/Action/Open opened]. * [[Image(source:trunk/images/imagery_small.png,link=)]] [wikitr:/Help/Menu/ImageryContextMenu Imagery Layer] - Holds a background retrieved from a tile server like Bing Aerial or other [wikitr:/Help/Menu/Imagery imagery]. * [[Image(source:trunk/images/layer/validator_small.png,link=)]] [wiki:Help/Menu/Validator Validator layer] - Highlights errors or [wiki:Help/Dialog/Validator warnings] for objects on the active data layer. * [[Image(source:trunk/images/dialogs/notes/note_open.png,15,link=)]] [wikitr:/Help/Menu/Notes Notes layer] - Holds [wiki:Help/Dialog/Notes Notes] from [osmwiki:Notes OSM]. Most layer types can have several instances in a JOSM session, but the validator and notes layers can exist only once. More layer types come with additional [wikitr:/Plugins plugins], e.g. [[Image(https://raw.githubusercontent.com/mapillary/josm-mapillary-plugin/master/images/icon16.png)]] [osmwiki:JOSM/Plugins/Mapillary Mapillary plugin].

This is important when items in one layer obscure those in layers below. You can reorder layers also by drag and drop. === Move Down === #LayerDown [[Image(source:trunk/images/dialogs/down.png,link=)]] **Down** moves the selected layers down one row in the layer stack. === Activate Layer === #ActivateLayer [[Image(source:trunk/images/dialogs/activate.svg,link=)]] ''Keyboard shortcut'': **{{{Shift+A}}}** ('''''release keys''''') then **{{{[0-9]}}}** - counting from the top **Activate** activates the selected layer. It is only possible to edit in an active Data layer. === Visibility === #VisibilityLayer [[Image(source:trunk/images/dialogs/layerlist/visibility.png,link=)]] Following hotkeys used to control visibility of top10 or bottom10 layers: * {{{Shift+S}}} ('''''release keys''''') then **{{{[0-9]}}}** - where 0 it the top layer; 9 - bottom * **{{{Alt+[0-9]}}}** - counting from the bottom; 1 - first from the bottom; 0 - bottom10 Once clicked on, it offers: * 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: * A slider to adjust the [[Image(source:trunk/images/dialogs/layerlist/transparency.png,16,link=)]] **Opacity** of selected layers. * A slider to adjust the [[Image(source:trunk/images/dialogs/layerlist/colorfulness.png,16,link=)]] **Colorfulness** of selected layers. * A slider to adjust the [[Image(source:trunk/images/dialogs/layerlist/gamma.png,16,link=)]] **Gamma** of selected layers. * A slider to adjust the [[Image(source:trunk/images/dialogs/layerlist/sharpness.png,16,link=)]] **Sharpness** of selected layers. Colorfulness, Gamma and Sharpness are only availible for imagery layers. For gpx layers you can choose one of 7 default colors. (Other colors are available via [Help/Action/LayerCustomizeColor Customize Color] in the gpx layer [wiki:Help/Menu/GPXLayer context menu]). [[Image(gpx_colors.png)]] Note: For ease of use you can use mouse scrolling to move a slider while the pointer is placed at the slider – no need to click-drag-release the slider picker. === Delete Layer === #DeleteLayer [[Image(source:trunk/images/dialogs/delete.png,link=)]] **Delete** permanently deletes the selected layers. **All unsaved changes will be discarded! ** If you try to delete an OSM data layer or Notes layer which contains changes, JOSM will open the [wiki:Help/Dialog/UnsavedChangesDialog Unsaved Changes window], asking to upload and/or save these changes. === Individual Buttons === There might be more buttons depending on the loaded [wiki:/Plugins plugins], e.g. [[Image(osm:source:/applications/editors/josm/plugins/rasterfilters/images/josm_filters_48.png,16,link=)]] [osmwiki:JOSM/Plugins/RasterFilters RasterFilters plugin]. ---- * Back to [wikitr:/Help/ToggleDialogs Windows] * Back to [wikitr:/Help Main Help]
