v35 v42 1 1 [[TranslatedPages]] 2 = Preferences > Map Settings = 2 [[PageOutline(2,Tabs)]] 3 3 4 [[Image(source:trunk/images/preferences/map.png)]] 4 = Preferences > Map Settings = 5 [[JOSMImage(preferences/map,link=)]] 5 6 6 7 Settings for the map projection and data interpretation 7 8 8 9 == Map Projection == 10 On each startup JOSM sets the projection method, the coordinate display format and the system of measurement back to user default settings. 9 11 10 You can change the map projection method between Mercator, and some others. Be aware that projections maybe only valid for a certain area of the world.[[BR]] 11 The default projection for JOSM is Mercator. This projection has certain advantages, one of them is that geometric figures (e.g. circles and rectangles) aren't deformed when displayed. This is useful for mapping. 12 === Projection method === 13 For the current session the projection method can be changed here. \\ 14 A list of common projections is offered and customs projections can be set. 12 15 13 JOSM is able to automatically reproject raster images from the projection of the source to the projection that is set in JOSM. To avoid having set an unsuitable projection for a long time JOSM resets the projection setting to Mercator at every restart. In [ExpertMode Expert mode] you can set another projection as default with the "Set as default" button. 16 Projection code:: shows the EPSG code for the projection. 17 Bounds:: shows the region where the projection is valid. \\ 18 Some projections are valid only for small parts of the world.\\ 14 19 15 You can also change the system of measurement here (Metric, Chinese, Imperial, Nautical Mile). (You can also change it in the [wiki:Help/StatusBar status bar].) 20 Common default projection for JOSM is Mercator (EPSG:3857). \\ 21 It has certain advantages, one of them is that geometric figures (e.g. circles and rectangles) aren't deformed when displayed. \\ 22 JOSM reprojects raster images from the projection of the source automatically to the current projection method. 16 23 17 == Map Paint Styles tab == #MapPaintStyles 24 Set as default:: 25 With this button the user default setting for the projection method is set. 26 It is visible in [wikitr:/Help/ExpertMode Expert mode] only, #14877. 18 27 19 In this section sources for displaying the data can be changed. Beside the internal styles also externals styles are presented and can be activated. 28 === Display coordinates as === 29 Set the user default coordinate format (Decimal, Degrees, Nautical or Projected Coordinates). 30 31 === System of measurement === 32 Set the user default system of measurement (Metric, Chinese, Imperial or Nautical Mile). 33 34 In the [wikitr:/Help/StatusBar status bar] the coordinate format and the system of measurement can be changed in the context menu for the current session. 35 So the numbers in ''Bounds'' may not fit to ''Display coordinates as''. 20 36 21 37 22 [[Image(MapPaintStylesPreferences.png)]] 38 == Map Paint Styles == #MapPaintStyles 39 In this tab the styles for displaying the data can be changed. Beside the internal styles also externals styles are presented and can be activated. 23 40 24 See [wiki:Styles] and [Dialog/MapPaint Map Styles Toggle Dialog]. 41 [[Image(MapPaintStylesPreferences.png,link=,40%)]] 25 42 26 == Tagging Presets tab == #TaggingPresets 27 ''If you want to learn how presets can also be added to the toolbar see - [Preferences/Toolbar Toolbar Customization]''[[br]] 28 ''If you want to use presets or need complete reference of presets see [wiki:Presets Presets]''[[br]] 43 See [wikitr:/Styles] and [wikitr:/Help/Dialog/MapPaint Map Styles panel]. 29 44 30 [Help/Concepts/Object#presets Presets] allow you to select predefined tags for [Concepts/Object objects]. From this area of the preferences menu you can choose which presets to use. 45 46 == Tagging Presets == #TaggingPresets 47 ''If you want to learn how presets can also be added to the toolbar see - [wikitr:/Help/Preferences/Toolbar Toolbar Customization]'' \\ 48 ''If you want to use presets or need complete reference of presets see [wikitr:/Presets Presets]'' \\ 49 50 [wikitr:/Help/Concepts/Object#presets Presets] allow you to select predefined tags for [wikitr:/Help/Concepts/Object objects]. From this area of the preferences menu you can choose which presets to use. 31 51 32 52 The preset list will be downloaded automatically, then you have two options: 33 53 34 54 === Activate preset(s) from available presets === 55 Use [[JOSMImage(preferences/activate-right)]] the blue, right arrow in the middle. \\ 56 Items on the right will appear in [wikitr:/Help/Menu/Presets Presets menu]. 35 57 36 Use [[Image(source:trunk/images/preferences/activate-right.png,20)]] the blue, right arrow in the middle. 37 38 Items on the right will appear in [wiki:Help/Menu/Presets Presets menu]. 39 40 [[Image(wiki:TaggingPresets:TaggingPresets.png,link=)]] 58 [[Image(wiki:TaggingPresets:TaggingPresets.png,link=,40%)]] 41 59 42 60 === Add a preset from the file === 61 Include one from a URL or local file (or network-located file or file in a Dropbox alternative) by clicking on the [[JOSMImage(dialogs/add)]] plus button on the right. 43 62 44 Include one from a URL or local file (or network-located file or file in a Dropbox alternative) by clicking on the [[Image(source:trunk/images/dialogs/add.png,20)]] plus button on the right.63 Adding presets requires a restart of JOSM. Then the [wikitr:/Introduction#Presets tagging presets can be selected as usual]. 45 64 46 65 47 Adding presets requires a restart of JOSM. Then the [wiki:Introduction#Presets tagging presets can be selected as usual]. 66 == File Backup ==#FileBackup 67 [[Image(josm_prefs_file_backup.png,link=,right,margin-left=10)]] 48 68 49 == File Backup == #BackupSettings 50 If you save geo data to a local file and the file already exists JOSM writes the data to a temporary file (with the suffix {{{~}}}). It then copies the temporary file to the target file. 51 In the File Backup settings you can specify whether JOSM should delete the temporary file or whether it should leave it as "backup" in the file system. 69 === Autosave === 70 * **Auto save enable**: enable or disable [wikitr:/Help/Action/AutoSave autosave] altogether (`autosave.enabled`) 71 * **Auto save interval**: set a custom value for the time interval in seconds (default is 300) (`autosave.interval`). 72 * **Auto save files per layer**: set a custom value for the number of backup files per data layer (default is 1) (`autosave.filesPerLayer`). \\ 73 If you increase it to 2, JOSM will not only save the last snapshot of your changes, but also the last but one (in case it differs from the last, otherwise an even older snapshot, if available). 52 74 53 1. Go to the tab **File backup** in the Map Preferences 54 1. Select or deselect the checkbox **Keep backup files** 75 === Backup === 76 * **Keep backup files when saving data layers**: enable or disable file backup of data files (`save.keepbackup`) \\ 77 If you save a data layer to a local file and the file already exists JOSM writes the data to a temporary file (with a tilde `~` as suffix). It then copies the temporary file to the target file. \\ 78 Here you can specify whether JOSM should delete the temporary file or whether it should leave it as "backup" in the file system. 55 79 56 See [Action/AutoSave#Preferences AutoSave Preferences] 80 === Notification === 81 * **Notification at each save**: choose if you want to see a small notification at each save (`autosave.notification`). 82 83 {{{#!comment 84 == See also == 85 }}} 86 57 87 ---- 58 Back to [ Action/Preferences Preferences][[Br]]59 Back to [wiki :/Help Main Help]88 Back to [wikitr:/Help/Action/Preferences Preferences dialog] \\ 89 Back to [wikitr:/Help Main Help]
