Open Street Map editor
JOSM is an extensible editor for OpenStreetMap (OSM) for Java 8. It supports loading GPX tracks, background imagery and OSM data from local sources as well as from online sources and allows to edit the OSM data (nodes, ways and relations) and their metadata tags. OpenStreetMap is a project aimed squarely at creating and providing free geographic data such as street maps to anyone who wants them.
