Tutorial: OpenHistoricalMap uploads from JOSM

Windows

Locate your JOSM settings folder

  • Windows 8: C:\Users\USERNAME\AppData\Roaming\JOSM
  • Windows 7/Vista: C:\Users\USERNAME\Application Data\JOSM
  • XP: C:\Documents and Settings\USERNAME\Application Data\JOSM

The official JOSM help has additional details https://josm.openstreetmap.de/wiki/Help/ResetPreferences

Copy and rename the folder

  • Make a copy of the JOSM folder. Simplest way is to select it and press Ctrl-C and Ctrl-V, it will create a folder Copy - JOSM. I've renamed the new folder for simplicity's sake to JOSM_OHM

Create new JOSM shortcut

  • Make a copy of the JOSM shortcut, or create a new shortcut for josm.exe or josm-tested.jar
  • Right-click on the shortcut, select "Properties" in the context menu.
  • In the tab "Shortcut", enter these parameters to "Target":
C:\Windows\System32\javaw.exe -Djosm.home=C:\Users\USERNAME\AppData\Roaming\JOSM_OHM -jar "C:\Program Files (x86)\JOSM\josm-tested.jar"
Settings of the JOSM shortcut

This assumes the default installation folders. Change them to point to your username, Java, and JOSM folders accordingly. Be mindful of the quotation marks, they are necessary.

(At this stage you can also enter additional parameters. You can e.g. force JOSM to reserve a certain amount of RAM with the parameter -Xmx0000M where 0000 are megabytes, e.g. -Xmx4096M for 4 gigabytes. Place the parameter anywhere between javaaw.exe and -jar. The official JOSM help pages list all the possible command-line parameters: https://josm.openstreetmap.de/wiki/Help/CommandLineOptions)

Point JOSM to the OpenHistoricalMap API

  • Open JOSM Images preference.png Preferences (F12) and JOSM settings connection.png Connection Settings.
  • Uncheck "Use the default OSM server URL", and enter at the field "OSM Server URL": http://www.openhistoricalmap.org/api/
    JOSM connection settings
  • Click "Validate" next to the field and wait for a green check-mark to appear next to the button. (If not, check Troubleshooting)
  • You first need to click "⏎ OK" to close the Preferences after validating. Then open Preferences again, and then input your username and password at Authentication. Otherwise JOSM will try to authenticate using the previous openstreetmap API, which will result in an error.
At this time of writing (July 2014), you cannot log into OHM by OAuth or secure HTTP authentication, so choose a password that does not function elsewhere in case it gets intercepted.
  • Enter the login details, and JOSM is ready to upload your edits onto OHM.

Linux/OSX

In the home directory, ~/.josm

Troubleshooting

If the server URL validation responds with a 404 error, you need to check that you have entered the correct URL. If the URL is correct, the connection might be down. Check the status at http://isitup.org/www.openhistoricalmap.org or in the IRC channel irc://irc.oftc.net #ohm
