To-fix JOSM plugin

This plugin makes To-Fix OpenStreetMap microtasking challenges available directly from within the JOSM editor.

Instead of picking new tasks and confirming accomplished tasks through the web interface of To-Fix on this plugin allows you to work with To-Fix tasks without ever having to switch out of JOSM.


  • Open "Preferences" in your JOSM editor
  • Click "Update plugins"
  • Select "Plugins" and check "tofix"
  • Confirm with "OK" and restart JOSM



  • Select "To-fix" from "Windows", the To-fix window will appear as a panel on your screen (at least one layer must be enabled to select options within Windows)
  • Select a task from the drop down.

Working with the plugin

Tasks tab

  • Skip: Click to select a new task at any time.
  • Not an error: Click if a task does not require any editing
  • Fixed: click when you are done editing on a task. This will automatically start the upload process. Fill in a comment like #to-fix:tigerdelta. After uploading, the plugin will download the next task.

Config tab

  • Slide the bar for setting the default download size in m².

Activation tab

  • Check Enable Tofix plugin to enable tofix plugin functionality. This is active by default.
