  • OpenStreetMap Disclaimer
    OpenStreetMap is not a complete or accurate map of the world and should not be used in such a manner that deficiencies, omissions, inaccuracies or errors could result in death, loss or injury. It is particularly important to realize that the maps might not be reliable. The maps are an iterative ongoing work-in-progress. We are aiming to produce maps which can be relied upon, equally well, or better than other maps. The openly-editable wiki nature of this mapping system may help us towards this goal, however it may also mean that there will always be some inaccuracies. You should make your own judgement about the accuracy of our maps. Always use our maps in conjunction with your senses, official sources and your common sense.

    For more information, we refer to the official disclaimer of OpenStreetMap project.
