The exact position of some borders are open to dispute by many countries, and will not be recognised by others. The borders used in these map overlays are generally obtained from datasets in the public domain, though some adjustments have been made to bring things more up to date or complete. However, due to the many current political disputes, no claim is made to the accuracy or even the existence of any international or national boundary, or any other feature, on these maps.
