Java OpenStreetMap Editor

Java OpenStreetMap Editor (JOSM) is a handy tool for anyone who wants to jump in and help edit or contribute to OpenStreetMap (OSM). It's all about teamwork when it comes to mapping, and with JOSM, you can easily tweak and add geographic info to the maps on OpenStreetMap.

Easy to Use Interface

This program is pretty cool because it doesn’t need any installation. It runs on Java and has a simple interface that makes it user-friendly. The main part of the screen shows you the map, while all sorts of options are neatly laid out around it.

Loading Maps Made Simple

To get started with JOSM, you can load maps from files saved on your computer in different formats like OSM, XML, JOZ, WMS, GPX, NMEA, JPG, and more. If you prefer, you can also grab maps directly from OpenStreetMap. Just keep in mind there are some limits on how much area you can download due to server rules.

Powerful Editing Features

This tool comes packed with features that let you make detailed edits. You can add new geographic elements or change existing ones. Want to adjust positions? No problem! You can create areas or polygons too—there’s a lot you can do!

Keep Maps Up-to-Date

When you're done editing, you have options! You can save your map locally or export it in GPX format for GPS devices. Plus, if you're ready to share your work with others, just upload it back to OpenStreetMap!

A Community Effort

If you're someone who loves mapping—whether it's as a hobbyist looking to update local info or a pro working with geographic data—this app lets you be part of the team improving the accuracy of OpenStreetMap's mapping database.
