JOSM (About this soundlisten ) (Java OpenStreetMap Editor) is a free software desktop editing tool for OpenStreetMap geodata created in Java, originally developed by Immanuel Scholz and currently maintained by Dirk Stöcker.[4] It has a lot of advanced features,[5] but also more complicated user interface than default online editor iD.

Some notable features of JOSM are importing GPX files (GPS tracks),[6] working with aerial imagery (including WMS, TMS and WMTS protocols), support for multiple cartographic projections, layers, relations editing,[7] data validation tools, data filtering, offline work,[8] presets and rendering styles.[9] JOSM provides more than 200 keyboard shortcuts for the core functions.[10]

Many additional features (like tools for drawing buildings, adding Wikipedia links or viewing data in 3D) are available through the plugins.[11][12][13][14] There are more than 100 of them in the repository.[15]


The first changeset was created on 27 September 2005.[16] The first beta version (which required Java 5)[17] was made available on 4 October 2005 and JOSM 1.0 was released on 22 January 2006.[1] The current versioning scheme, using code changeset number, was introduced in 2008.[18]

In 2014 the project logo was replaced with the current artwork, which won a design contest.[19] From this year stable releases are identified with additional YY.MM internal version number (following r6763 - 14.01[20]), however they may not exactly reflect the release date.[21]

Since revision 10786 (16.07) released on 12 August 2016, support for Java versions earlier than 8 has been dropped.[2]


The highest number of edits in OSM is done using JOSM.[22] The software was used to perform several large scale OSM imports, including TIGER data in the United States.[23]

JOSM can also be used for editing an OSM sister project OpenHistoricalMap.[24] It's included as a package in many Linux distributions like Ubuntu,[25][26] Debian,[27] Fedora,[28] Arch Linux[29] and the OSGEO Live DVD[30]

Various tutorials are available. The LearnOSM Tutorial, translated in 16 languages, has a section on JOSM.[31] It covers the editing process, the tools, the plugins, the presets, the imagery functionalities, conflict resolution and other features.
