Java OpenStreetMap Editor

JOSM is an editor for ​OpenStreetMap written in Java 1.5. The current version supports stand alone GPX tracks, GPX track data from the OSM database and existing nodes, ways and metadata tags from the OSM database.

News

Changeover to josm.openstreetmap.de - if you still have any bookmarks that include "josm.eigenheimstrasse.de", please change them as the forward is going to be removed some time. The SVN respository has been slightly re-structured (by introducing a trunk/branch level) so if you do checkouts you will want to check out from "trunk" instead of getting the full repository.

(Other) news is announced ​here.

Due to changes in the server you must be running a version of JOSM newer than r345.
