要运行JOSM你的电脑需要先安装Java 8以上的运行环境。遗憾的是，暂时还没有支持Mac OS 10.3.x的Java 1.5。
- 从Java SE安装Java运行环境
$ sudo aptitude install sun-java6-jre
- 输入 (使用root):
$ apt-get install sun-java6-jre
注意: 如果你还安装了其他的JVM。你需要指定sun java vm的执行路径(/usr/lib/jvm/java-6-sun/java)或者使用"update-java-alternatives -s java-6-sun"更新系统配置。
If you are interested in latest josm-development and plugins use the OpenStreetMap Gentoo Overlay. By using the "x86"-keyword you get a stable release, the "~x86"-keyword installs the svn-version.
There are many plugins already available as ebuilds. Look at https://svn.openstreetmap.org/applications/utils/gentoo/ for a complete list.
JOSM packages are available in the openSUSE's build service, in the home:rodrigomoya repository:

The jar file needs to be passed to the Java 1.5 runtime. This step is different to the various platforms:
java -jar josm.jar in a shell. There are also some tutorial videos. One describes the steps to set up KDE for starting JOSM by clicking on the JAR file. Get the tutorials from one of the mirrors listed at openstreetmap.de.
Ubuntu users have a good tutorial at UbuntuForums.
If you need to use it from behind a proxy, you can tell it to the java runtime like
java -Dhttp.proxyHost=192.168.1.1 -Dhttp.proxyPort=3128 -jar josm.jar, with the IP and port of your proxy.
If you need ipv6, you can tell it to the java runtime with
java -Djava.net.preferIPv6Addresses=true -Dhttp.proxyHost=proxy.ipv6.uni-leipzig.de -Dhttp.proxyPort=3128 -jar josm/josm-snapshot-xxx.jar
The proxy here is only mentioned because the openstreetmap-server doesn't support ipv6 yet.
java -jar josm.jar
You can also set up a shortcut to the JOSM.jar file which allows the inclusion of additional parameters. I have the following as the short cut "Target" in my Start Menu which starts a control prompt window (useful to see progress of uploads/downloads), loads JOSM in its separate window, and assigns 512mb of memory for the process which dramatically speeds up operation when editing dense data. Change "path" to the full path of your josm-latest.jar file.
C:\WINDOWS\system32\java.exe -jar -Xmx512M "C:\path\josm-latest.jar"
Mac OS X systems
You need Mac OS 10.4 or better. 10.3 will not do the job. In 10.4.x, simply double click on the jar file and Java 1.5 should load the JOSM jar file. If you need to allocate more memory to JOSM (in order to edit larger files), the following script will help:
java -jar -Xmx256M -XX:MaxPermSize=256M josm-latest.jar
- If you have a GPX tracklog file of the ways you want to map, start JOSM. Choose File → Open to select and load your track. JOSM will automatically fit the workspace to the bounding box of your track.
- If you don't have a GPX tracklog file then you may want to use data collected from other users. See Korea Mapping Guide
- If you want to play around while learning how to use JOSM without changing the data on the server then just don't upload (downloading is OK), delete the layers you changed, and then start over.
- Always download before editing even if you are using data stored on your own computer.
- To exchange data with the server ensure you have entered your username and passphrase in the preferences of JOSM. Your username is not your wiki username but the email address you used for registering.
- Now choose File → Download from OSM. In the following dialog ensure that the checkbox to get OSM data is enabled and press the OK button. Always download before uploading.
- If the track is too long, the server will refuse to send you the OSM data for that area. Zoom in a bit to restrict the request to a reasonable size.
- Wait a bit until all the data has been received. If there are existing ways of your area in the database, you will now see them in JOSM.
- Now start your editing session. Be careful when changing existing data, as streets and nodes can have lots of tags assigned.
- The JOSM manual is available online here, and these pages can also be accessed by pressing F1 from within JOSM. If you really mess things up simply delete the layers that have been changed before you do an upload and then start over.
- See here for a list of default shortcuts.
See also JOSM/Advanced Tricks (more tips for more experienced users)
- After installing a plugin, you have to visit the preferences where you can enable and disable each plugin individually
- For users new to OSM, it is recommended to use a presets file for easier tagging. Ask for one in the mailing list or User:SlowRider
- To see the ways in different colours and thicknesses, install the mappaint plugin
- If you do not have a wheelmouse, you can zoom in and out using the key combo Ctrl-. (period) and Ctrl-, (comma).
- If you mapped one lane of a motorway, find here a tool which creates the opposite lane for you.
Automatically Matching Photos to GPS traces
One of the problems when out mapping with a GPS is trying to keep accurate notes about the street names as you pass each junction. If you have a digital camera to take out with you, JOSM can help.
- take a photo of your GPS screen/display showing the time (on the GPS) when you start
As you are travelling around, take a picture at appropriate places/junctions/road signs. Then, when you get home with your completed GPS track uploaded into JOSM:
- In the "Layers" box, top right
- Right click on the GPS track layer, for the layer you have just uploaded. Note: you must do it from a layer you have just uploaded, and not from data that was downloaded from OSM, as that apparently no longer has a timestamp.
- Select "Import Images" (or possibly "import photos")
- Right click the photos layer,
- Sync the clocks using the (camera's timestamp on the) photo you took at the start (of the GPS screen/display clock)
- If you do not have a picture of the GPS for some reason, turn on the camera and GPS now. Work out the time difference between them. Now, subtract or add this to the time shown in the 'sync clocks' photo dialog.
Automatically Matching Sound Recordings to GPS traces
As of build 549 there is a similar facility for applying and synchronising sound recordings.
- Dictate details of the streets names and points of interest as you pass them. If you are conveniently able to, just before you dictate a description of each feature, put a named/numbered waypoint into your GPS. If you can see the display, ideally also note the waypoint name/number in you audio description. Make sure you put a waypoint at the beginning at the same time as saying "NOW" or some such so you can align the two in JOSM. If you aren't making waypoints, put yourself at a location such as a junction that you'll be able to identify from the GPS track.
Then you get home with your completed GPS track uploaded into JOSM, if you have explicit waypoints:
- Load your waypoints from the GPX file in a Marker layer. Usually this is an automatic side effect of opening the GPX file, but if your GPS stores these as named trackpoints, you can convert these to waypoints by right clicking on the GPX layer and selecting Markers from Named Points. You should see the names of the markers on the map display.
- In the "Layers" box (top right) right click on the Marker Layer that got created and select Apply Audio, and choose the WAV file for the audio commentary. (JAVA doesn't support all audio formats so you may have to convert the file, e.g. using Audacity: 8,000 samples per second at 16 bit samples will work).
- You should now see audio icons for each waypoint, which you can click to play the audio. You can also use the Audio menu.
If you don't have explicit waypoints (n.b. applies from build 551 only):
- In the "Layers" box (top right) right click on the GPX layer and select Make Sampled Audio Layer, and choose the WAV file for the audio commentary. Limitations as above.
- You should now see audio icons spaced out at reasonable intervals along your track, which you can play by clicking them. These will be spaced a minimum of 15 seconds and 75m apart. (These defaults are suitable for a cyclist at 5m/s - 11mph or 18km/h; they can be altered in Advanced Preferences with the values for "marker.audiosampleminsecs" and "marker.audiosampleminmetres" respectively. In a car in an urban environment you might want 7 seconds, on the open road maybe only 3 seconds, and if walking, perhaps 75 seconds; and for higher or lower density overall, obviously adjust both).
In both cases:
- You can play, pause, resume, jump forward and back, and go to the next or previous waypoint, from the Audio menu. Using the button bar controls in the Preferences pane you can also put these bttons on the button bar in a familiar arrangement. Full stop (period) is a keyboard equivalent for play/pause/resume.
- Synchronize the audio with the waypoints or identified location by clicking the marker for which you synchronised until you hear your cue ("NOW") and pause. Then select Sychronize Audio by right clicking on the Marker Layer. Synchronization only applies to that and later points, so if you did pause part way through, you can also resync on a later point.
JOSM error messages
Error while parsing. An error has occurred
The most likely cause of the above error is that the server is slow and has not sent the required response back to JOSM. If this occurs just try uploading the data again, and JOSM will resume from where it left off.
If you get error 412 precondition failed, it means that something changed on server in unexpected way. Try deleting affected objects.
JOSM seems to start okay, but the window is blank
If you have the fancy, compiz/beryl graphics stuff enabled, then this may happen. The solution is simple, add the following line to the user profile:
Here's a few notes from a beginner's (Parsingphase) first couple of days working on OSM, using the JOSM editor (on Mac OS X).
- "Installing" JOSM on OS X is a cinch — just download and double-click the .jar file.
- Use a two-button mouse with a scroll wheel — it makes life much easier. Right-dragging moves the map, the scrollwheel zooms.
- Otherwise, command-click (aka "Apple-click") does a right click, ctrl-arrows to move the map, and ctrl-, and ctrl-. to zoom.
- Because it starts with a dot, your ~/.josm directory will be invisible to the Finder. You either have to move the plugins into it from the command line, or open the folder using "Go to Folder..." ("Go" menu in the Finder).
- There's a Mac OS X look and feel under the Edit → Preferences menu; it doesn't actually change any functionality but it fits in ;)
Points for all platforms
- Get the "mappaint" rendering mode. It makes it far easier to see what's going on in your maps (and even work out where on earth you are), at the expense of slightly higher processor load on your machine (my PowerBook 12" copes fine).
- Upload and download small areas, frequently. The less time you've got unstored or unchecked changes, the lower the risk of conflict with other users.
- Always download an area before you start work on it, even if you have your own GPX data.
- Always download the area you are going to upload before doing so, to get any modifications made by other users and avoid overwriting data.
- When downloading an area you get all the data within the rectangular bounding box you choose, and also, where any way within that bounding box extends outside the box it is completely downloaded. It therefore becomes difficult to precisely know which areas you have downloaded full data for. If you check the "Draw boundaries of downloaded data" box (found in Display Preferences), a yellow rectangle is drawn around all the areas for which full data has been downloaded. Caution should be exercised when adding new data to areas outside these rectangles as it may duplicate already existing data, which you have not downloaded.
- A "small area" to start with might either be that from a short GPX track you've taken, or about a 1-km square around a known location. This equates to about 0.06° of latitude/longitude (give or take polar distortion), so enter an area about that size into the File → Download from OSM → Bounding Box.
- Rural areas with less detail might work better with larger areas — the 1-km recommendation is about right for a suburb of London.
- Once you're viewing an area in JOSM, at whatever zoom level, the JOSM download dialog box will default to the currently viewed area.
- It's very easy to select more than you expect to, particularly when making "ways". Open the "Current Selection" panel (Alt-e, fifth button up on the left) to keep an eye on what you've selected.
- Switch back to "select" mode regularly and click on nothing or type Ctrl-Shift-A to clear your select list.
Why don't my changes appear?
- See Map Features for how to specify that your way is a road/railway etc, and what type. If you're not sure of the type (e.g. primary/secondary) be conservative and choose the lesser (e.g. secondary).
