Java OpenStreetMap Editor


JOSM is an editor for OpenStreetMap (OSM) written in Java 1.6. Currently it supports loading stand alone GPX tracks and GPX track data from the OSM database as well as loading and editing existing nodes, ways, metadata tags and relations from the OSM database.

  • Try JOSM applet (very new, may be defective - please report bugs, currently you need to be logged in before or loading and saving preferences wont work)
  • Get the source:
    • From the official Subversion repository (recommended): svn co
    • From the unofficial GitHub mirror: git clone git://
  • See Developers Guide or Translations Guide
  • The Ubuntu JOSM project on launchpad
