Offline highly expandable map editor
Although it has a relatively steep learning curve, JOSM is popular among experienced editors thanks to its plugins and stability. There are other editors for OpenStreetMap data, like iD or Potlatch 2. JOSM is a feature-rich editor with an interface which can seem complex at first. Have a look at the comparison of editors if you're still unsure which editor to choose.
JOSM can be downloaded from the JOSM homepage.
Many Linux distributions offer JOSM packages, see JOSM/Linux.
