JOSM(1)

NAME
josm - Java OpenStreetMap Editor

SYNOPSIS
josm

DESCRIPTION
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.
