JOSM is an editor for OpenStreetMap written in Java 8.
OpenStreetMap is a project aimed squarely at creating and providing free geographic data such as street maps to anyone who wants them. It allows you to view, edit and use geographical data in a collaborative way from anywhere on earth. The project was started because most maps you think of as free actually have legal or technical restrictions on their use, holding back people from using them in creative, productive or unexpected ways.

JOSM files are saved according to the XDG Base Directory Specification:
- If the directory $HOME/.josm exists, all files are stored there.
The following options can be set by using Java system properties (i.e. -Dkey=value passed to java, or specified inside JAVA_OPTS).
Set the JOSM preferences directory.
Set the JOSM user data directory.
Set the JOSM cache directory.
Relocate all 3 directories to homedir. Cache directory will be in <homedir>/cache.
Change the JOSM directory name.
Specify an alternate Java environment.
Specify Java options. For example, to use a HTTP proxy server with this program, set this environment variable to something like JAVA_OPTS="-Dhttp.proxyHost=yourProxyURL" before starting josm.
JOSM was originally designed and coded by Immanuel Scholz, and is now maintained by the OpenStreetMap community.
The current JOSM maintainer is Dirk Stöcker. A lot of administration work is done by Paul Hartmann and Vincent Privat.
