[[TranslatedPages(outdated=This page is incomplete. The individual dialogs for adding customized sources are not explained.)]] [[PageOutline(2-4,Table of Content)]] = Preferences > Imagery = [[JOSMImage(preferences/imagery,48,middle,link=,margin-right=20)]] **Modify list of imagery layers displayed in the Imagery menu** Four tabs are available for adding, deleting and modifying [#Imageryproviders imagery sources], general [#Settings imagery settings], [#OffsetBooksmarks offset bookmarks] and [#Cache imagery cache settings]. **Note**: To display an imagery (''background'') in the [wikitr:/Help/MapView Mapview] use the [wikitr:/Help/Menu/Imagery Imagery menu] instead. == Imagery providers ==#Imageryproviders Here you can modify the list of imageries which appear in the [wikitr:/Help/Menu/Imagery Imagery menu]. A lot of predefined sources are available, additionally modifiying existing and definining customized entries is possible. JOSM supports WMS, TMS and WTMS servers. === Available default entries ===#DefaultEntries The top left list contains all available sources. If you select a source and if it is not provided global its bounds are displayed on the little map on the top right. You can filter this list by typing in the box above. You can use parts of the source name, the country code (e.g. cz), the country name (e.g. czech republic, use the country name in the language JOSM is set to), the source category (photo, elevation, historicphoto, map, historicmap, osmbasedmap, quality assurance or other) or the URL. \\ \\ [[Image(PreferencesImageryProviders.png​,45%,link=,right,margin-left=10)]] * To update (reload from JOSM server) the list of default entries click on the [[JOSMImage(dialogs/refresh)]] button between the two lists. * To copy an entry from the top list to the bottom list select it in the top list and click on the [[JOSMImage(preferences/activate-down)]] ''**Activate**'' button between the two lists. **Note:** To add an entry to the top list of default entries read the [wiki:/Maps#Documentation Documentation] and edit [wiki:/Maps#Listofsources Maps] or its subpages (for advanced users). === Selected entries ===#SelectedEntries The bottom list contains all entries which will appear in the [wikitr:/Help/Menu/Imagery Imagery menu]. Activated default entries are highlighted green in both lists. (The green color doesn't say anything about the state/health of the servers they mention, nor the validity of the URLs.) * To add an custom WMS/TMS/WMTS source click on the respective button on the right, [[JOSMImage(dialogs/add_wms)]], [[JOSMImage(dialogs/add_tms)]] or [[JOSMImage(dialogs/add_wmts)]], and follow the instructions. * To delete an entry in the bottom list select it and click on the [[JOSMImage(dialogs/delete)]] button. * To modify an entry, double click on the field in the table and modify its content. The bottom list is saved in advanced preference as value of key: `imagery.entries` == Settings ==#Settings Here you can edit some general imagery settings. === Common Settings ===#CommonSettings Sharpen (requires layer re-add):: adds a sharpening post-process. Values are ''None'', ''Soft'' or ''Sharp''. As this changes the entry in the list, the imagery layer has to be re-added. \\ ''Advance preference: `imagery.sharpen_level` Tiles zoom offset:: offset between calculated zoom level and zoom level used to download and show tiles. Negative values (underzoom) will result in lower resolution of imagery useful in HiDPI displays, positive values (overzoom) will result in higher resolution, at the cost of increased memory consumption. \\ ''Advance preference: `imagery.generic.zoom_offset` === WMS Settings ===#WmsSettings [[Image(PreferencesImagerySettings.png​,link=,45%,right,margin-left=10)]] Auto zoom by default:: whether the zoom levels of the WMS imagery layer should be adjusted when zooming in or out of the map. \\ ''Advance preference: `imagery.wms.default_autozoom` (default: `true`) Simultaneous connections:: Number of simultaneous connections. \\ ''Advance preference: `imagery.wms.loader.maxjobs` (default: `3`)'' Tile size:: size of each tile. \\ ''Advance preference: `imagery.wms.imageSize` (default: `512`)'' === TMS Settings ===#TmsSettings Auto zoom by default:: whether the zoom levels of the TMS imagery layer should be adjusted when zooming in or out of the map. \\ ''Advance preference: `imagery.generic.default_autozoom` (default: `true`)'' Autoload tiles by default:: whether TMS tiles should be loaded automatically or only manually. \\ ''Advance preference: `imagery.generic.default_autoload` (default: `true`)'' Min. zoom level:: minimum zoom level for TMS layers. \\ ''Advance preference: `imagery.tms.min_zoom_lvl` (default: `2`)'' Max. zoom level:: maximum zoom level for TMS layers. \\ ''Advance preference: `imagery.tms.max_zoom_lvl` (default: `20`)'' Add to slippymap chooser:: whether TMS imageries should be available in download dialog. \\ ''Advance preference: `imagery.tms.add_to_slippymap_chooser` (default: `true`)'' Maximum concurrent downloads:: global maxmium number of parallel TMS imagery downloads. \\ ''Advance preference: `imagery.tms.tmsloader.maxjobs` (default: `25`)'' Maximum concurrent downloads per host:: maximum number of parallel TMS imagery downloads per host. \\ ''Advance preference: `imagery.tms.tmsloader.maxjobsperhost` (default: `6`)'' == Offset bookmarks ==#OffsetBooksmarks Here are listed all offset bookmarks which can easily be added via [[JOSMImage(mapmode/adjustimg)]] [wikitr:/Help/Action/ImageryAdjust New offset] in the Imagery menu and the [[JOSMImage(dialogs/layerlist)]] [wikitr:/Help/Dialog/LayerList layers list] panel's [wikitr:/Help/Menu/ImageryContextMenu context menu]. \\ ''Advance preference: `imagery.offsetbookmarks`'' [[Image(PreferencesImageryOffsetBookmarks.png​​,link=,45%)]] == Cache ==#Cache Here are listed all cached images (tiles) from each source. You can use the ''**clear**'' button in each line to delete the cached images for each source. You may need a JOSM restart to take effect in the Mapview. **Note**: A possibly existing ''Mapnik'' entry [#17054 stems from] using the slippy map shown by the JOSM [wikitr:/Help/Action/Download#Slippymap download dialog] in older JOSM versions. You can safely delete it. === Cache settings ===#CacheSettings Tile cache directory:: location of the imagery tile cache, see [wikitr:/Help/Preferences#JOSMpreferencedatacachedirectories default directories]. \\ ''Advance preference: `imagery.generic.loader.cachedir`'' Maximum size of disk cache (per imagery) in MB:: quota option per imagery. \\ ''Advance preference: `imagery.cache.max_disk_size` (default: `512`)'' [[Image(PreferencesImageryCache.png​,link=,45%)]] ---- Back to [wikitr:/Help/Action/Preferences Preferences dialog] \\ Back to [wikitr:/Help/Menu/Edit Edit Menu] \\ Back to [wikitr:/Help/Menu Main Menu] \\ Back to [wikitr:/Help Main Help]
